Australia is enormous, varied, and home to some of the best multi-day walks on the planet. Coastal cliffs, alpine ridgelines, ancient sand islands, desert ranges, temperate rainforest — the only real problem is choosing which to do first.

For people thinking about their first proper hiking adventure, multi-day trails are the ones that change you. Day walks are great. A six-day end-to-end with everything on your back is a different animal entirely. Here are the ten Aussie treks worth doing — three you can knock off in a long weekend, and seven that earn the "trek of a lifetime" tag.

End-to-end. 223km. 16-20 days.

The Red Centre on foot. The Larapinta follows the West MacDonnells west from Alice Springs, traversing the Chewings and Heavitree ranges and weaving through landmarks like Simpsons Gap, Ellery Creek, Ormiston Gorge and Glen Helen. Twelve trail access points break it into sections, so you can walk it in chunks over a few trips if you don't have three weeks spare.

Plan around: April–September only. Daytime temps drop from 35°C+ to manageable. Food drops are essential for end-to-enders. Most camps have tent sites and picnic tables; trailheads have water tanks. Refs: parksandwildlife.nt.gov.au, larapintatrail.com.au.

End-to-end. 104km. 5-6 days.

The Great Ocean Walk does the cliff-top stretch from Apollo Bay to the Twelve Apostles. Wild coastline on your left, Otway rainforest cutting in and out of view, with a pre-planned ending: time your last day to hit the Apostles at sunset and the trip writes itself.

Camping or comfort: 12 walk-in campsites for the immersive version, or you can do it B&B-to-B&B with shuttle services. The farmstay options around Red Johanna are seriously good if you want a softer take. Ref: greatoceanwalk.com.au.

Circuit. 75km. 8-11 days. Brutal.

The toughest serious walk in Australia, and a notable badge of honour if you finish it. Mention the Western Arthurs to any experienced bushwalker and you'll get the cheek-puff and "ooh, that's a toughie" reaction. Steep, mud-infested paths, knee-crunching descents on loose scree, sharp rock scrambles, and weather that can turn lethal in any season. Most walkers will need to backtrack at least once because the route disappears.

The reward: 22 major peaks, 30 lakes, raw wilderness, and a guarantee of solitude — fewer people walk it in a year than tackle most other listed walks in a week. Carry topographic maps. Read John Chapman's South West Tasmania before you commit. Ref: john.chapman.name/tas-wa.html.

End-to-end. 655km. 40-50 days. Six national parks.

The mainland's premier multi-week alpine adventure. From the gold-rush ghost town of Walhalla in Victoria's High Country, the AAWT runs the spine of the Australian Alps all the way to Parliament House in Canberra. Total elevation gain over the trail is roughly equivalent to climbing Everest three times.

Sometimes well-marked, sometimes not at all (in wilderness sections). You need real navigation skills — map and compass, not GPS — and the experience to deal with rapid alpine weather changes in summer (yes, summer). Food drops at the few road crossings are essential. The reward is some of the most beautiful and remote walking on the continent. Ref: australianalps.environment.gov.au.

End-to-end. 135km. 6-7 days.

Lighthouse to lighthouse — Cape Naturaliste in the north, Cape Leeuwin in the south. The trail runs through the famous Margaret River wine country, alternating cliff-top headlands with stretches of pristine beach, with the Boranup Karri Forest as a magnificent inland section. Springtime adds a wildflower show.

Trail conditions vary: old 4WD tracks, well-graded single-track, rocky pathway, and several long sandy beach sections. Camping along the trail is plentiful, but the smart move is mixing it with a few B&Bs and accessing wineries on rest days. Tour operators run fully guided versions for those who'd rather walk than carry. Ref: capetocapetrack.com.au.

End-to-end. 84km. 6-8 days.

The world's largest sand island, on foot. Crystal lakes (Lake McKenzie, Lake Wabby), towering subtropical rainforest growing out of pure sand, multi-coloured sand cliffs, and dunes you can wade up to your shins in. Easy walking for the most part — soft sand and leaf litter — with occasional dune climbs that quickly remind your calves you're not on a sealed track.

Self-sufficient camping only — bookings essential, water available at some camps but must be treated. Refs: parks.des.qld.gov.au, tourfraserisland.com.au.

Loop. 44km. 2-3 days.

The best long-weekend trek in Victoria, hands down. From Tidal River the loop heads inland through fern-shaded gullies and boardwalk swamps to reach Sealers Cove — paradise. From there the trail traces the coastal fringe past Refuge Cove, Waterloo Bay, the Prom Lighthouse, then back via Little Oberon Bay to Tidal River.

Why it's brilliant: short enough for first-time multi-day walkers, varied enough to feel like much longer, and family-friendly Tidal River as your start/finish point. Punches well above its 44km weight. Ref: parks.vic.gov.au.

Loop. 100km. 4-5 days. Not a marked route.

This one's a bit of an insider's choice — not an official Great Walk, but a self-guided High Country loop that takes in Crosscut Saw, the Bluff, Howqua Valley and finishes back via Craig's Hut (yes, the one from The Man From Snowy River). The Crosscut Saw ridgeline traverse is one of those experiences that's genuinely hard to describe to anyone who hasn't done it.

Difficulty: high. Steep ascents, exposed alpine sections, real navigation required. Experienced walkers can self-guide with good topo maps; everyone else should consider Tour de Trails who run this route guided. Mountain-cattlemen huts add to the atmosphere. Ref: tourdetrails.com.

End-to-end. 65km / 82km with the Lake St Clair extension. 5-9 days.

The most famous walk in the country, and rightly so. From Cradle Mountain south through the Tasmanian highlands — sub-alpine moors, ancient rainforest, eucalypt forest, golden buttongrass plains, glacially-carved valleys. World Heritage listed for good reason.

Booking is required (numbers are limited Oct-May), and the system fills up months in advance. Accommodation is hut sleeping platforms or designated campsites — huts can be full when you arrive so always carry a tent. Side trips that make the trip: Cradle Mountain summit, Mount Ossa (Tassie's highest), the Labyrinth, and Lake St Clair (deepest lake in Australia). Ref: overlandtrack.com.au.

End-to-end. 1200km. 50-60 days. Or whatever bite-sized chunk you fancy.

South Australia's monster trail, running from the southern Fleurieu Peninsula all the way to the dramatic red walls of the Flinders Ranges. Almost no one walks it end-to-end — but that's fine, because the trail is divided into very walkable multi-day sections, and they each give you a different SA: wineries and gourmet villages around the Adelaide Hills, coastal cliffs and whales on the Fleurieu, arid Wilpena Pound country in the north.

Best sections to start with: the Wilpena Pound loop (3-4 days) for outback drama; the Adelaide Hills section (3-5 days) for the food-and-wine version. Refs: heysentrail.asn.au.

Most of these treks need a base camp the night before and after — and a hot shower at the end is non-negotiable. Browse our Campsite Explorer for sites near the major trailheads:

If this is your first multi-day, start with Wilsons Prom (44km loop, family-friendly trailhead). If you want a transformative experience, do the Larapinta in sections. If you want to be properly humbled, take a year, get fit, then book the Western Arthurs.

The good ones change you a bit. Pick one, set a date, and start walking around with a weighted pack a few months out — that's the only training that actually matters.

Closing note: Victoria's Grampians Peaks Trail is now fully open end-to-end (160km, 13 days), and is fast becoming the southern equivalent of the Larapinta. Worth adding to the next list.
