Cathedral Gorge, Bungle Bungles Range, Purnululu National Park, Australia
It's true that the Blue Mountains of Australia are known for the amazing number of slot canyons within the range. But not to be outdone is the Bungle Bungles Range in Purnululu National Park. This World Heritage Site is a collection of sandstone and conglomerates formed into dome-shaped towers by wind and rainfall over millions of years. Within these formations are cracks, slot canyons, gorges and natural amphitheaters, Cathedral Gorge among them. One could wander the slot canyons here for days, even weeks. It is a fascinating and unique landscape, and Cathedral Gorge is one of the most popular among visitors for its ease of access.
