Covering the whole peninsula north of Denham is an area of low scrub, salt lakes and red sandy dunes, home to the rare bilby, mallee fowl and woma python. There's a scattering of rough camp sites alongside brilliant white beaches, all accessible via 4WD (deflate tyres to 20psi). Don't miss the fantastic Wanamalu Trail (3km return), which follows the clifftop between Cape Peron and Skipjack Point. Spot marine life in the crystal waters below.
2WD vehicles can enter only as far as the old Peron Homestead , where there's a walk around the shearing sheds, and an artesian-bore hot tub. Tours to the park start at around $180 per person from Denham or Monkey Mia. Groups should consider hiring a 4WD from Denham for the same price.
