"A 2.63-billion-year-old granite wall shaped like a giant wave in the WA wheatbelt."
Wave Rock, Perth Overview
Wave Rock is a granite formation near Hyden, Western Australia, about 15 m high and 110 m long, curved to resemble a giant breaking ocean wave. It is the best-known face of Hyden Rock, a granite inselberg dated to roughly 2.63 billion years old, with its shape carved by chemical weathering and water erosion. The site lies around 296 km (roughly a 4-hour drive) east-southeast of Perth, inside the 160-hectare Hyden Wildlife Park, which also holds walking trails and the nearby Hippo's Yawn rock formation.
Wave Rock's striped, overhanging face is a section of Hyden Rock, a granite outcrop rising from Western Australia's wheatbelt farmland. Its curve formed through chemical weathering at the rock's base combined with water and wind erosion, while vertical streaks of colour come from algae and mineral run-off draining down the surface. A water-catchment wall built in 1928 and renovated in 1951 still channels rainfall into a storage dam. Visitors can walk along the base of the wave, climb to the top of Hyden Rock for wheatbelt views, and follow a short trail to Hippo's Yawn, a separate rock overhang shaped like a yawning hippopotamus, a few hundred metres away.
