Wave Rock is a granite cliff 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 at being 2700 million years old, which are amongst the oldest in Australia
Hippo's Yawn consists of an unusually shaped granite tor that was formerly part of the larger outcrop. This is the second most visited site in Hyden. It is connected to Wave Rock and the car park by a loop walking track, approx 1 km long. Vehicle access is also provided.
A 15 minute drive north of Wave Rock you will see a "giant" lurching out of the bushland. This massive granite rock formation is known as the Humps - grab your hat, sun screen and water bottle and explore!
The name "Mulka" comes from an Aboriginal Legend associated with the cave. As you enter the cave (take a few moments for your eyes to adjust) and look at the walls and note the many hand stencils believed to representing adults and children. The stencils are made by placing the hand on the rock, then blowing over it with pigment. When the hand is removed, a negative impression remains.
During spring the bushland comes alive with an explosion of colour. Every way you turn, there will be a different colour and variety of amazing flowers to see. It is a photographer's delight and you will spend hours searching for the rare orchids that grow in the area. Some of the orchids that you will find include; Spider, Donkey, Bee, Cowslip, Ant, Dragon, and different Sun Orchids.
