Starting from the Echidna Chasm car park off the Great Northern Highway, Purnululu National Park, this walk takes you past the Osmand Lookout, then into Echidna Chasm via the Echidna Chasm Trail. A little walk off the main track will take you to a lookout where you can get exceptional views of the Osmand Range. After visiting the lookout, you'll follow the dry creek bed that leads into Echidna Chasm. The start of the walk is hot and exposed, but soon you'll be in the cool shelter of the tall chasm, surrounded by towering walls of conglomerate rock with remarkable colour variations. Signs along the walk describe how the chasm was formed, and the boulders along the path let you have an idea about the origin of the Bungle Bungle Range. The walk gets more challenging towards the end of the chasm, requiring some scrambling over large boulders and climbing up ladders. Sturdy footwear is recommended as walking over the boulders can be tough on the ankles. Daytime temperatures can exceed 40°C, so be sure to bring plenty of drinking water, a hat and sunscreen. The best time of the day to visit Echidna Chasm is around noon when the sun is directly overhead. This is the only time when sunlight penetrates into the chasm, creating an amazing spectacle with light bouncing off the walls. Let us begin by acknowledging the Traditional Custodians of the land on which we travel today, and pay our respects to their Elders past and present.
