Australia’s Best Nature Road Trips 

Which Australian routes are all about the journey, not the destination?

Most road trips get planned backwards. We pick the destination first, then treat the drive as something to get through rather than enjoy. But often, the route is the main event. Ancient rainforest gives way to red desert. A coastline keeps unfolding for hours. Some drives pack more into the journey than the destination ever could.

So at Redspot, we set out to find which drives put the most nature on show. We analysed 25 of Australia’s best-known road trips and scored each one on ecosystem diversity, wildlife, coastline and protected land. The result? A ranking of the routes that pack the richest slice of natural Australia into a single trip.

Whether you’re planning a weekend escape or a full lap of the country, dive into the research below and find the route that packs the most nature into every kilometre… and find the drive that proves the scenic route is always worth taking.

The best nature road trips in Australia

The Grand Pacific Drive takes the crown as the top road trip for nature lovers, scoring 68.7/100 on our index. Its 158.8km route serves up scenery that’s both diverse and consistent, all the way from Sydney to the Shoalhaven. Along the way, you’ll find 18.9 campsites and 30.2 named water features every 100km, plus an internationally recognised wetland and two natural heritage-listed places. It’s also one of the most coastal drives in our study, with almost 60% of the route within 5km of the sea.

Planning a Queensland escape? The Great Tropical Drive comes in second, scoring 64.6/100. Across its 556.3km route, you’ll pass through an average of 4.6 subregions every 150km. Almost a third (32.4%) of its corridor is protected, and it’s home to three natural heritage-listed places. The route still has 61.4% of its native vegetation and one of the highest wildlife counts in our study. Add an 877m elevation range and 18.7 campsites every 100km, and you’ll have plenty of chances to get out, explore and rest up.

Only a few states made the top 10, with no routes from the Northern Territory, South Australia or Western Australia. The Great Alpine Road is Victoria’s only entry, placing seventh with a score of 55.6/100.

The best nature road trips by length 

Top short nature road trips (under 520km)

Short on time but big on scenery? These routes pack the most nature into the shortest drives. Leading the way is the Grand Pacific Drive, our top nature road trip overall and the shortest route overall at 158.8km.

The Great Eastern Drive in Tasmania ranks second among the short road trips and third overall, scoring 61.7/100. The route runs for just under 200km, starting north of Hobart and following the east coast up to the Bay of Fires. It has the highest proportion of native vegetation of the short nature road trips(81.1%), three internationally recognised wetlands, and 75.7% of the route within 5km of the coast. With 21.5 named water features and 18 campsites every 100km, you’ll have plenty of reasons to pull over and take it all in.

NSW’s Waterfall Way takes third place with a score of 59.9/100. It stands out for ecosystem diversity, crossing an average of eight subregions every 150km. That’s more than double the 3.8 average across all 25 routes. The 170.8km drive also has 609 species of wildlife and an elevation range of 1,316m.

Rounding out the top four, Victoria’s Great Alpine Road (55.6/100) lives up to its name, with the widest elevation range in our study at 1,369m. It also has 70.7% native vegetation and 17.4 campsites every 100km.

Top medium nature road trips (520-1,065km)

The Great Tropical Drive takes the crown among medium-length nature road trips, scoring 64.6/100. Tasmania’s Western Wilds comes in second with 61.6/100. This 544.8km route has one of the highest proportions of native vegetation in our study (83.4%) and the most named water features of any route, at 34.1 every 100km. It’s also the most protected route we analysed: 41.2% of the land within 10km of the road is protected, so you’ll spend long stretches among Tasmania’s wild, biodiverse landscapes.

Want to go further? The Legendary Pacific Coast stretches 990km across Queensland and NSW and ranks third among the medium routes, scoring 56.8/100. It’s a wildlife hotspot, with the highest species count of the medium-length road trips and 52.7% native vegetation. It also has more campsites than any other route, at 23.3 every 100km, so it’s easy to break up the drive with a few nights in nature.

Top long nature road trips (over 1,065km)

If you’ve got time to really soak it all in, the Sydney to Melbourne Coastal Drive is the one to beat, leading our long road trips with a score of 55.5/100. About a third (33.X%) of its 1,446.4km route sits within 5km of the south-east coast. Along the way, you’ll find four internationally recognised wetlands, three natural heritage-listed places and 641 species of wildlife. With more than 15 campsites and 12 named water features every 100km, there’s no shortage of places to pull over and take in the view.

The Pacific Coast Way comes in second, scoring 51.8/100. Running 1,912.9km from the Gold Coast to Cairns, it’s a camper’s dream: it has 18.8 campsites every 100km, the most of any long route and well above the 11.5 average across all 25 routes. You’ll also pass three natural heritage-listed places, three internationally recognised wetlands and 774 species of wildlife, so you’ll see plenty of Queensland’s flora and fauna.

Sydney to Melbourne, take two: the Sydney to Melbourne Heritage Drive places third with 51.0/100. The 1,110.9km route crosses an average of 4.1 subregions every 150km, above the 3.8 average, and passes six natural heritage-listed places. Add a 660m elevation range, and the landscape keeps changing as you go.

The best nature road trips by state 

The best nature road trips in New South Wales and the Australian Capital Territory

If you want a nature-packed road trip close to the east coast, NSW and the ACT have plenty to offer. The Grand Pacific Drive tops the list for NSW and the ACT with 68.7/100, followed by Waterfall Way (59.9/100) and the Legendary Pacific Coast (56.8/100).

The best nature road trips in Victoria 

Victoria has plenty to offer road trippers who love nature, and the Great Alpine Road is its top-ranked route, scoring 55.6/100. Over 345km, it climbs through a 1,369m elevation range, the widest in our study, and crosses an average of 5.85 subregions every 150km, well above the 3.8 average. Along the way, you’ll find 70.7% native vegetation, an internationally recognised wetland and a natural heritage-listed place. With 17.4 campsites every 100km, there are plenty of chances to pull over, set up camp and explore.

The Sydney to Melbourne Coastal Drive comes in a close second with 55.5/100, just 0.1 points behind. The Sydney to Melbourne Heritage Drive places third with 51.0/100, making it a great pick if you want a longer journey through a mix of natural environments.

The best nature road trips in Queensland  

In Queensland, the Great Tropical Drive takes the top spot, scoring 64.6/100 across its 556.3km route. It also ranks second in Australia overall.

The Legendary Pacific Coast comes in second, scoring 56.8/100 across its 990km journey through Queensland and NSW. The Pacific Coast Way rounds out the top three with 51.8/100.

The best nature road trips in the Northern Territory   

The Northern Territory is home to some of Australia’s most remote landscapes, and its routes have some of the highest proportions of native vegetation in our study. Nature’s Way comes out on top with a score of 47.5/100. Starting and finishing in Darwin, the 877.4km loop has 91.9% of its native vegetation intact and passes an internationally recognised wetland, two natural heritage-listed places and 607 species of wildlife. 

The Red Centre Way takes second place, scoring 40.0/100 across 1,228.4km. It has the highest proportion of native vegetation in our study at 100%. Campsites are more spread out, at 2.8 every 100km, so the route is better suited to experienced outback travellers who plan their overnight stops ahead.

Just 0.1 points behind in third is Explorers Way, with 39.9/100. At 3,062.3km, it’s the longest route in our study, crossing South Australia and the Northern Territory for a huge cross-section of inland Australia. It also has the highest wildlife count of all 25 routes at 930.8 species, along with 89.8% native vegetation and a 594m elevation range. With 6.3 campsites every 100km, you can break up the journey and take in the outback’s plants and wildlife at your own pace.

The best nature road trips in South Australia 

In South Australia, the Southern Ocean Drive comes out on top with a score of 40.0/100. The 543.4km route crosses an average of 4.17 subregions every 150km, above the 3.8 average, and passes an internationally recognised wetland. It also covers a good stretch of the south coast, with 43.1% of the drive within 5km of the ocean. 

Explorers Way comes in second with 39.9/100. At 3,062.3km, it’s the longest route in our study, linking South Australia and the Northern Territory. Flinders Ranges and Outback takes third with 33.2/100. The 497.5km route has 20.3 named water features every 100km, and 18.4% of the drive sits within 5km of the coast.

South Australia’s routes sit further down the national ranking, with the Southern Ocean Drive placing 19th out of 25. Even so, between the coastline, the wetlands and the outback, there’s plenty to explore.

The best nature road trips in Tasmania 

Tasmania shines within our rankings, with two routes in the national top four. The Great Eastern Drive leads the state with 61.7/100, followed by the Western Wilds on 61.6/100, just 0.1 points behind. Both routes have some of the highest proportions of native vegetation in our study, and the Western Wilds has the most protected land of any route.

Southern Edge places third with 36.1/100. It’s the only one of the three outside the national top 10, but at under 300km, it’s a handy option for a shorter trip.

The best nature road trips in Western Australia 

Western Australia’s top nature road trip is the Coral Coast Highway, scoring 48.7/100. Almost 40% of its 1,660.7km route runs within 5km of the coast, and 81.6% retains its native vegetation. It also passes six natural heritage-listed places, the joint-most of any route in our study, along with 641 species. That makes it a great pick for a longer trip packed with wildlife and bushland.

The South West Edge places second with 45.6/100, and it stands out for wetlands. The 1,159.9km drive passes six internationally recognised wetlands, the joint most of any route, plus 12.67 named water features and 13.1 campsites every 100km. There are plenty of chances to get out and explore along the way.

Warlu Way comes in third with 38.8/100. It’s a bushland standout, with 98.8% native vegetation, one of the highest proportions in our study. The route also passes three natural heritage-listed places and two internationally recognised wetlands.

No WA route cracks the national top 10, but the Coral Coast Highway comes close in 11th.

Top nature road trips by factor 

Top Australian road trips for ecosystem diversity 

For travellers looking to experience the greatest variety of ecosystems, Waterfall Way in New South Wales leads the category. The route crosses an average of eight different subregions in every 150km of driving, and ranks fifth on the overall national index.

Top Australian road trips for national parks  

Tasmania’s Western Wilds keeps you closest to protected land: 41.2% of the land within 10km of the route is protected, including national parks and reserves. It ranks fourth overall, with a score of 61.6/100.

Top Australian road trips for wetlands

The South West Edge in WA passes six internationally recognised wetlands, more than any other route in our study. It ranks 16th overall, with a score of 45.6/100.

Top Australian road trips for heritage-listed places 

Two routes share the top spot, each passing six natural heritage-listed places: the Sydney to Melbourne Heritage Drive 11th overall, 51.0/100 and WA’s Coral Coast Highway 14th overall, 48.7/100. Either one is a great pick if heritage-listed landscapes are on your bucket list.

Top Australian road trips for water features  

For the most named lakes, lagoons, waterfalls, springs and swimming spots, roadtrippers should look no further than Western Wilds in Tasmania. The route features 34.14 named water features per 100km, and with an index score of 61.6, it ranks as the fourth-best nature road trip in Australia. 

Top Australian road trips for coastal exposure

Tasmania’s Great Eastern Drive runs within 5km of the coast for 75.7% of its length, the highest share of any route. It ranks third overall, with a score of 61.7/100.

Top Australian road trips for vegetation 

For roadtrippers hoping to immerse themselves in native vegetation, Red Centre Way in the Northern Territory is the obvious choice, with a perfect 100% score for remaining native flora. 

Top Australian road trips for elevation

Victoria’s Great Alpine Road has the widest elevation range of any route, at 1,369m, so the scenery keeps shifting as you climb. It ranks seventh overall, with a score of 55.6/100.

Top Australian road trips for wildlife 

Explorers Way, which links SA and the NT, has the highest wildlife count of any route, with 930.8 comparable species. It ranks 21st overall, with a score of 39.9/100.

Top Australian road trips for campers  

The Legendary Pacific Coast has more campsites than any other route, with 23.3 every 100km along its 990km stretch through NSW and Queensland. It ranks sixth overall, with a score of 56.8/100.

Yasmyn Schneps – Head of Operations, at Redspot comments on the research: 

“It’s easy to plan a road trip around where you’ll end up, but the real magic often happens along the way. Our research shows just how much Australia’s road trips pack in, from rainforest and wetlands to outback drives where almost none of the native bush has been cleared. We ranked 25 routes on everything from ecosystem diversity and elevation to coastline and wildlife, so travellers can find the drive that suits them.

“Whether you’re heading off for a weekend or a few months, a little planning goes a long way. Choose a vehicle that suits your route, check road conditions before you set off, plan fuel and overnight stops on remote stretches, and keep an eye out for wildlife, especially around dawn and dusk. From SUVs and vans to 4WDs, our team can help you find the right vehicle for your trip. With one-way rentals, the only direction you need to worry about is forward.”

About the data 

• What the index measures
  • Ranks 25 sealed touring routes that state and territory tourism authorities promote end to end, using each authority’s own start and finish points
  • Measures ten features of nature inside a corridor 10 km either side of every route
  • Each measure comes from an authoritative national dataset (nine of the ten are government) and each carries equal weight of 10%
  • Scored 0–100, where 100 is a route in the top 10% of the field on all ten measures

  Which Australian road trips actually put you closest to the most nature? It is a question usually answered on opinion: a writer’s favourites, a reader poll, a list of places that photograph well. We answered it by measurement, using the same national datasets governments use to map protected land, threatened habitat and vegetation cover.

• What We Measured

  Measure	What it counts	Source	What it does not tell you
  Ecosystem diversity	Expected subregions per 150 km window	IBRA 7.1, DCCEEW	Subregion boundaries are ecological, not visual
  Protected areas	% of corridor protected	CAPAD 2024, DCCEEW	Whether a reserve is open to visitors
  Wetlands	Internationally listed wetlands	Australian Ramsar Wetlands, DCCEEW	A wetland’s size or condition
  Heritage	Natural heritage places	World / National / Commonwealth heritage lists, DCCEEW	Distinct destinations (listing counts)
  Water features	Named water features per 100 km	ICSM Composite Gazetteer, Geoscience Australia	Whether a feature holds water or can be reached from the road
  Coastal exposure	% of route within 5 km of coast	Geoscience Australia coastline	Whether the sea is actually in view
  Vegetation	% native vegetation remaining	NVIS 7.0, DCCEEW	Vegetation condition (remnant scrub counts as old growth does)
  Wildlife	Comparable wildlife species	Atlas of Living Australia	Whether any of it is visible from the car
  Terrain	Elevation range (m)	Copernicus DEM GLO-30	Difficulty, or scenery
  Camping	Listed campsites per 100 km	Full Range Camping	Unlisted bush camping, or how wild a camp is

• How Each Measure Is Calculated
  • Ecosystem diversity: Interim Biogeographic Regionalisation for Australia (IBRA), the national map of ecologically distinct country, divides Australia into 89 bioregions and 419 finer subregions. A raw count would reward length, so the measure is distance-rarefied: subregions inside the corridor are recorded every kilometre, then averaged over a fixed 150 km window sliding along the route. It reports the ecosystems you would expect to cross in a standard length of driving, comparable between a 159 km route and a 3,062 km one.
  • Protected areas: The share of corridor area inside one of the Collaborative Australian Protected Areas Database’s (CAPAD) 14,492 terrestrial protected areas, across every IUCN category from strict nature reserves to Indigenous Protected Areas. Reserves nest inside one another, so overlaps are dissolved before the area is taken, and no ground is counted twice. Marine protected areas are excluded.
  • Wetlands: Australia has 67 Ramsar-listed wetlands, mapped by DCCEEW as 120 polygons; a site is counted once, however many polygons carry it. It behaves as a rare-event measure: most routes score zero or one, and the highest in the study is 6, so a single listing can move a route several places.
  • Heritage: Only places listed for natural rather than cultural values: 16 of Australia’s 21 World Heritage properties, 40 of 143 National Heritage places and 32 of 391 Commonwealth Heritage places. A place on two registers under the same name is counted once; the same area under different names is not merged, so read it as a count of listings. Of the 46 places reaching a corridor, 31 are within 5 km of the road, and only those are named in the campaign. Seven listings are Defence land: counted in the measure, never named as places to visit.
  • Water features: 15,738 waterfalls, gorges, lakes and lagoons, waterholes, rockholes, pools and springs nationally, from the ICSM Composite Gazetteer, counted per 100 km. Farm dams, bores, tanks, marine features, beaches and caves are excluded.
  • Coastal exposure: The share of the route line within 5 km of Geoscience Australia’s mapped coastline. Five kilometres rather than the 10 km corridor, because the question is whether the sea is part of the drive. Measured on the line rather than the corridor, so it is identical at a 10 km or a 20 km buffer.
  • Vegetation: The share of corridor still carrying any native vegetation type, from NVIS 7.0’s Major Vegetation Groups on a 100 m grid; 29 groups appear in these corridors. Cleared and built land, sea and estuaries, and unmapped ground are excluded from the total. NVIS is modelled rather than directly observed, and its accuracy varies by state.
  • Wildlife: Vertebrate records only: mammals, birds, reptiles and amphibians. Raw counts across these 25 corridors span 97-fold, from 156,903 to 15.2 million, which measures observers as much as animals. The scored figure is therefore a Hurlbert rarefaction: the species you would expect in a random sample of 156,903 records, the same sample size for every corridor. The Atlas blurs the coordinates of threatened species by design, and records are cumulative, so a species recorded once decades ago still counts.
  • Terrain: The gap between the corridor’s typical low and typical high point, taken as the 5th-to-95th percentile of elevation so a single peak or gorge cannot dominate. Copernicus DEM GLO-30 is a 30 m surface model, so its elevations include canopy and buildings, which is why a robust percentile range is used.
  • Camping: Listed campsites per 100 km from Full Range Camping’s directory of human-checked listings. Five categories are counted: free camps, campgrounds, caravan parks, rest areas and low-cost sites (7,260 sites nationally).

  Note: Red Centre Way (sealed 2WD option) reaches 100.0% on vegetation because NVIS classifies each 100 m cell by the vegetation covering it, and a two-lane road reserve is narrower than that. Read it as no mapped clearing in the corridor, not as untouched country.

• The 25 Routes
  

  Four rules decided the list:

  • Promoted end to end as a named touring route by a state or territory tourism authority, using that authority’s own start and finish points
  • Sealed throughout, so drivable in a standard 2WD
  • Under about 3,000 km. One route sits just over it: Explorers Way runs 3,062 km and was kept rather than cut short of its published finish
  • Every state and territory represented

  Unsealed routes such as the Savannah Way, the Gibb River Road, the Darling River Run, Binns Track and the Outback Way were excluded. This is a shortlist of well-known drives, not every route an authority promotes. The routes are not all independent of one another. 12 pairs share more than a tenth of their length, and at the extreme, Great Ocean Road runs 99.8% inside the Great Southern Touring Route. The authorities promote both, as a short drive and as a leg of a longer one, so both are here. Where a shorter route outscores the longer one containing it, that is the index measuring nature per kilometre.

  Distances are the driving distance between each route’s own published endpoints on the current road network, so they will not always match the headline figure on the linked page: authorities variously quote a return trip, a single state’s leg, a multi-day itinerary with side trips, or a network of connected routes. Where the difference is large, the note below says which.

  Capital, Coast & Country: VisitCanberra publishes this touring route as a PDF rather than a web page.

  Coral Coast Highway: Tourism WA’s 3,277 km headline is Perth to Exmouth and back. We measure the one-way drive.

  Explorers Way: Tourism NT and the SATC promote this jointly. We measure the direct Stuart Highway drive Adelaide-Darwin, the ‘3,000 kilometre journey’ both describe; Tourism NT’s 14-day itinerary totals more because it includes side trips to Uluru and Kings Canyon. The SATC’s own Explorers Way page covers the South Australian leg only, 1,142 km to Coober Pedy.

  Flinders Ranges & Outback (Explorers Way SA leg): The SATC publishes this as the Explorers Way’s South Australian leg rather than as a separate road trip, and that page runs 1,142 km on to Coober Pedy. We stop at Wilpena Pound, which is the Flinders Ranges portion, hence the shorter distance.

  Grand Pacific Drive: Destination NSW describes the Grand Pacific Drive as about 140 km, Royal National Park to the Shoalhaven, and separately lists a 2-day itinerary at 260 km. We measure the drive between the route’s own published endpoints, Royal National Park to Jervis Bay (Huskisson), which is further south in the same region: 158.8 km.

  Great Inland Way: The route’s own official site. Tourism and Events Queensland publishes the Queensland stretch alone at 1,863 km.

  Great Tropical Drive: TEQ presents the Great Tropical Drive as a network of 26 routes. We measure the sealed core loop out of Cairns, excluding Cooktown and the Bloomfield Track.

  Kosciuszko Alpine Way: When the route list was set, Visit NSW listed this as a four-day, 500 km journey from Canberra; its journey map now shows a 171.5 km leg from Cooma to Khancoban. We measure the drive from Canberra through Jindabyne, Thredbo and Khancoban, continuing via Tumbarumba to Tumut.

  Sydney to Melbourne Coastal Drive: Visit Victoria publishes the corridor as the Melbourne to Sydney coastal route; we drive it Sydney to Melbourne.

  Warlu Way: Tourism WA’s ‘almost 3,000 km’ covers the full Warlu Way network of four interconnected routes. We measure the sealed coastal spine, Exmouth to Broome.

• Index Scoring
  • Each of the ten measures is rescaled across the 25 routes, so the lowest measured value scores 0 and the highest scores 100
  • The ten rescaled scores are averaged with equal weight, 10% each. Higher is always better; nothing is inverted, and no measure is grouped with another
  • That average is then divided by what a top-decile score on all ten would average, so an index score of 100 means a route in the top 10% of the field on every measure. It is a division by one constant and changes no route’s position relative to another
• Handing Route Length

  Longer routes cross more country, so some measures would reward distance rather than nature. Three things guard against that:

  • Ecosystem diversity is distance-rarefied in a fixed 150 km sliding window
  • Water features and campsites are measured per 100 km
  • Every route is also ranked within its own length band, and the shorter bands are read separately

  The result is an index that runs against length rather than with it: Spearman −0.398 between index score and route distance, a moderate negative relationship

  One asymmetry worth noting, the 150 km window slides in one-kilometre steps, so the shortest drives have only one independent window (Grand Pacific Drive, Great Eastern Drive, Great Ocean Road, Southern Edge and Waterfall Way are each scored on effectively a single window) while the longest averages 20 and settles towards its own middle. Rescoring every route on its best 150 km window instead of its average removes the asymmetry entirely and moves a typical route 1.2 places. Grand Pacific Drive still finishes first.

• Stability Testing

  We rebuilt the index several different ways and watched what moved to test stability. We reweighted the ten measures at random 500 times over. We dropped each measure in turn and scored the field on the remaining nine. We doubled the corridor to 20 km either side of the route and measured everything again. And we re-scored the whole thing with the count-based measures converted to per-100-km, to check the order was not an artifact of how route length is handled.

  The results showed the overall order holds up. Across the random reweightings a typical route shifts about 1.7 places, and removing an entire measure moves it at most 2.9. Doubling the corridor width produces almost the same ranking (Spearman +0.926), which matters because 10 km either side is a judgement call rather than a natural boundary.

  What the testing supports is the shape of the table. Grand Pacific Drive and Great Tropical Drive finish in the top three in 96% and 81% of the reweighted runs, so the leading pair is a real result and not an artefact of the equal weighting we adopted. Grand Pacific Drive takes first place in 77% of them. Below the top, the tiers hold, but individual places are less stable.

• Limitations
  • These are measures of what is in the landscape, not of how it looks from the driver’s seat. Crossing three ecological subregions in an hour does not mean the view changes three times
  • Wildlife records reflect how many people have been looking as well as what is there, which is why they are adjusted to a common sampling effort
  • Vegetation mapping is modelled at 100 m and shows what grows in the corridor, not what is visible from the road
  • A low score means a route packs less measured nature into each kilometre, not that it has less to see.
• Sources and Disclaimer

  Eight of the ten measures are derived from Australian Government data: the Department of Climate Change, Energy, the Environment and Water (IBRA 7.1, CAPAD 2024, Australian Ramsar Wetlands, the World, National and Commonwealth Heritage lists, NVIS 7.0), Geoscience Australia (ICSM Composite Gazetteer, coastline) and the Atlas of Living Australia. Terrain is sourced from the Copernicus DEM GLO-30, while campsite data is sourced from Full Range Camping. All data sources collected September 2026.
