Best for adventure: Karijini National Park, WA

Karijini, in WA’s remote Pilbara, is arguably Australia’s most-dramatic national park. It’s a semi-arid landscape of red dirt and spinifex that conceals an almost-subterranean underworld of plunging canyons, waterfalls, icy pools and sunken gardens. The best way to explore the park is on foot, but be warned: while the gorge walks are mostly short, the trails can be very strenuous. Think steep climbs on loose rocks, stairs, ladders and even a “spider-walk” through a narrow chute of water.

Karijini is remote (1370km from Perth) and undeveloped, but well suited to adventurous caravanners with an off-grid setup. The two campgrounds are unpowered, but a site at Karijini Eco Retreat also gets you a hot shower.
