Australia has some of the world's best multi-day hiking trails — coastal cliffs, world heritage sand islands, alpine wilderness, and ancient ranges. The trick is picking one that matches your fitness, your time, and the season.

Here are five Aussie classics, all of which can be done as proper end-to-end multi-day expeditions OR cherry-picked for shorter day-walks.

Distance: ~100km · Time: 5-8 days end-to-end · Difficulty: easy to moderate

The Great Ocean Road's better-known sibling — same coastline, no traffic. From Apollo Bay west to within sight of the Twelve Apostles. Cliff-top vantage points, hidden coves, Otway rainforest sections, beach walks at low tide.

• Best season: September-April (avoid June-July storms)
• Highlights: Apollo Bay start, Cape Otway lighthouse, Aire River, Johanna Beach, Twelve Apostles finish
• Camping: 12 walk-in hike camps; or do it B&B-to-B&B with shuttle services

Even one day walking the cliff-top section feels significant. The full multi-day is one of the great Aussie walks.

Distance: ~8km · Time: 3-4 hours one way · Difficulty: easy to moderate

The day-walking gem of NSW Central Coast. Bouddi National Park's coastal track from Putty Beach to MacMasters Beach, with Gerrin Point lookout (1km from Putty Beach) being the standout — panoramic views over Maitland Bay and Bouddi Marine Park.

• Best season: year-round, spring/autumn ideal
• Highlights: Gerrin Point Lookout, Maitland Bay (with the wreck of SS Maitland visible at low tide), whale watching June-November
• Pack a picnic — beautiful spots throughout
• 2-3 hour family day-walk; can also be broken up into shorter sections

Easy access from Sydney (1.5 hours) makes this the perfect weekend introduction to coastal walking.

Distance: 90km · Time: 6-8 days · Difficulty: easy to challenging in places

Walk the world's largest sand island. Soft sand underfoot most of the way, with surprisingly varied scenery — perched freshwater lakes, ancient rainforest growing in pure sand, multi-coloured sand dunes, the famous Indian Head and Sandy Cape.

• Best season: April-October (avoid jellyfish season + summer humidity)
• Highlights: Lake McKenzie (perched freshwater lake), Lake Wabby, Central Station rainforest, Indian Head sea views, Sandy Cape
• Self-sufficient camping only — bookings essential through QLD Parks
• Treat all water before drinking

Can be split into shorter sections if multi-day backpacking isn't your thing — the island's 4WD-friendly so 4WD camp + day walks combo works well.

Distance: 1,200km · Time: 60+ days end-to-end (most do sections) · Difficulty: easy to challenging

One of the world's great long-distance walks. Cape Jervis on the south coast all the way to Parachilna Gorge in the Flinders Ranges. Coastal sections, Adelaide Hills wineries, Barossa Valley, and the spectacular outback ranges of the Flinders.

• Best season: April-November (avoid summer in the Flinders)
• Section pick — coastal Fleurieu (easy, family-friendly) or Wilpena Pound (outback ranges, spectacular)
• Heysen Trail huts and farm-stay accommodation along the route
• Friends of the Heysen Trail (heysentrail.asn.au) publish detailed section guides

Distance: 65km (82km with Lake St Clair extension) · Time: 5-9 days · Difficulty: moderate to challenging

Australia's most famous multi-day walk. Cradle Mountain to Lake St Clair, through Tasmanian Wilderness World Heritage Area. Sub-alpine moors, ancient rainforest, glacial valleys, alpine meadows. Bookings required (limited numbers).

• Best season: October-May (book months ahead)
• Side trips that earn the name: Cradle Mountain summit, Mount Ossa (Tassie's highest), the Labyrinth, Lake St Clair
• Huts available but often full — always carry a tent
• Weather flips fast — pack proper wet-weather gear regardless of forecast

• Check with the relevant national park / state authority for permits, bookings, current conditions
• Lodge a trip plan with a friend or local police if going remote
• Carry a PLB (Personal Locator Beacon) for any genuinely remote walking
• Pack the snake-bite SMART bandages + a proper first aid kit
• Train for it. Do shorter walks with a loaded pack in the months before

Most multi-day hikes start or end near a town with caravan parks or bush camps. Browse our Campsite Explorer to find pre- and post-hike campsites.

For first-timers: Bouddi (NSW) day-walk to test if you like it, Wilsons Promontory Circuit (VIC) for a multi-day, then graduate to the Overland or Great Ocean Walk. The Heysen and Larapinta are once-in-a-lifetime trips that need real prep.

Get good boots, a proper pack, and start training. The trail will reward you.
