Hyden is situated 340 kilometres east of Perth. More than 130,000 tourists visit the town every year on their way to the famous Wave Rock. Wave Rock is just four kilometres east of Hyden on a nature reserve of some 160 hectares. The Rock is a granite cliff, 15 metres high and 110 long, shaped remarkably like a huge wave. Geologists believe the original granite formation has been sculptured and coloured by weather, water and chemical erosion over 2.7 billion years to take on its wave like character. Other natural attractions in the area include Hippo's Yawn and Mulka's Cave.
