Crystal Caves of Yanchep National Park

Although threatened gondwanan species and ancient bacteria forming moon-milk can be seen on cave tours in Yanchep, it is worthy to note that more recent icons such as Sleeping Beauty, Queen Victoria and a pair of hugging Polar Bears also present themselves in Crystal Cave.

Travellers must be wary though of entry into Yonderup Cave, where crocodiles and the demons pit lie within the butcher's cold room, and experience doubly fraught with danger as you enter only with hardhat and cavers torch. Narrow crevices open up into large caverns, which means crawling and climbing.

The caves of Yanchep National Park range from narrow tunnels and vertical shafts to large caverns containing streams and pools. More than 400 caves have been recorded in the park and several of these are open for a variety of experiences.
