The largest state, Western Australia, has a low population and much of it is extremely dry. There are huge distances between interesting areas. Access is a major planning problem. Most bushwalking is in the southwest corner, but there are interesting areas elsewhere.
Mundaring Weir: The area directly east of Perth has some good walking through jarrah forests. There are one-day and overnight walks based on the Bibbulmun Track. Suitable for most of the year except hottest summer.
Monadnocks: A series of granite peaks southeast of Perth. With good tracks and camping facilities the peaks make good one-day and overnight walks. Suitable all year except summer.
Stirling Range: A rugged range north of Albany. The west end provides excellent one-day walks to the isolated summits. The east end of the park has a rough three-day, ridge-top traverse of the peaks that is suitable for experienced walkers. Best visited in spring for the wildflowers.
Cape to Cape: A marked five-day walking track follows the coast from Cape Naturaliste to Cape Leeuwin. This passes close to Margaret River. The track has many access points and is good for shorter walks as well. Suitable all year round.
Southern Coastline: A series of national parks along the coast provide excellent wilder-ness-style extended walks. D’Entrecasteaux, Walpole-Nornalup, Fitzgerald River and Cape Le Grand are the major parks. One-day walks are also possible. Spring and autumn are the best walking seasons.
Bibbulmun Track: A marked 964 km track that runs from Perth to Albany and takes around seven weeks to walk. Shelter huts, water and toilets are provided at each campsite. Best time to walk the track is spring.
Murchison River: The river is the main feature of the Kalbarri National Park north of Perth. Most walks follow the river gorge and range from one to five days. Suitable most of the year except summer.
Bungle Bungles (Purnululu): Rounded rocky domes dominate this park in the north of the state. Walking is confined to the narrow canyons and gorges and one-day and overnight walks are popular. Limited access to the area is by four-wheel drive only. Suitable for the dry seasons of autumn to spring.
Kimberley: A huge tropical wilderness area in the north of the state. This vast area has many rivers and plateaux to explore. Walking is unlimited for those prepared to explore. Access is difficult and it is only suitable for extended walking trips. Avoid the wet season; most walking is done in winter.
