Wave Rock (Nyungar: Katter Kich) is a natural rock formation that is shaped like a tall breaking ocean wave.
The "wave" is about 15 m (50 ft) high and around 110 m (360 ft) long. It forms the north side of a solitary hill, which is known as "Hyden Rock".
This hill, which is a granite inselberg, lies about 3 km (2 mi) east of the small town of Hyden and 296 km (184 mi) east-southeast of Perth, Western Australia.
Wave Rock and Hyden Rock are part of a 160 ha (395-acre) nature reserve, Hyden Wildlife Park. More than 100,000 tourists visit every year
