Wave Rock in Hyden, Western Australia, is a striking natural formation shaped like a giant ocean wave, rising 15 metres high and stretching 100 metres long. Visitors can enjoy walking trails around the rock, explore nearby formations such as Hippo’s Yawn and Mulka’s Cave, and experience Lake Magic’s colour changing waters. Notably, Wave Rock is estimated to be 2.7 billion years old, and is one of the world’s oldest geological features.
