DPaW (the state government Department of Parks and Wildlife) maintain’s WA’s parks and to enter most parks, you need to pay an entry fee or buy a pass. The DPaW website (dpaw.wa.gov.au) contains details of all passes, which you can buy online, as well as useful information about all of WA’s national parks. You can also obtain a pass from the entry station (often unattended), local DPaW offices and some visitor centres. Note that fees only apply if arriving by vehicle; walking or cycling in is free. Camping in a national park attracts an additional fee.
