Wave Rock, a granite cliff, is 15 metres high and 110 metres long. Its rounded like shape has been caused by weathering and water erosion which has undercut the base and left a rounded overhang. Water from the springs running down the rock during wetter months dissolve minerals adding to the colouring of the wave. In 1960, crystals from Hyden Rock were dated as being 2700 million years old, amongst the oldest in Australia.
There are numerous walk trails around Wave Rock including a rock and bush walk around the rock to see native flowers and birds.
