The Wave Rock is an all natural rock formation that is formed similar to a tall smashing ocean wave. The "Wave" is around 14 m (46 ft) high and also around 110 m (360 ft.) long. It forms the north side of a solitary hill that is often known as "Hyden Rock." This hill, which is a granite inselberg, is situated around 3 km (2 miles) east of the small town of Hyden and 296 km (184 miles) east-southeast of Perth, Western Australia. Wave Rock and Hyden Rock are part of a 160 ha (395 acre) nature reserve, Hyden Wildlife Park.
A wall structure lies above Wave Rock and around halfway up Hyden Rock and follows the contours of the wall. It accumulates as well as funnels rainwater to a storage dam. The wall and dam were built in December 1928 by the Public Works Department for the original settlers of East Karlgarin District. Each was renovated in 1951 to maximize water capacity for the Hyden Township.
