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.

Further Information

Crystal cave, recorded by Yanchep’s first European settler Mr Henry White over 100 years ago, has a number of still active areas where speliotherms such as stalagmites, helictites, columns and shawls continue to form.

Classified as an epiphreatic stream cave, crystal formations estimated at over 60 000 years old and up to 2m in length are formed when winter rains dissolve small amounts of surface cap rock that is then redeposited on the roof and floor of the cavern below.
