The Bungle Bugle is located in the Purnululu National Park. These tiger-striped, beehive-shaped sandstone domes rise 300m out of the arid landscape. The Bungle Bungles gain their tiger-stripes from black algae growth that permeates the more porous layers of the rock, and a glossy orange build up of manganese and iron staining. The access road to the Bungles is unsealed and is best suited to larger 4WD vehicles. The access road is only 55 km long but takes some 1.5 to 2 hours to travel in reasonable conditions.
