Starting from Wave Rock Caravan Park, Hyden, this walk takes you on a circuit, visiting Hippo's Yawn along the way. It is a universally accessible walk that features an abundance of wildflowers as well. Hippo's Yawn is named after its interesting resemblance to a hippo yawning, and the cave itself is 13 metres tall. There are patches of tiny ground orchids such as green hoods and showier ones. There is also a chart about orchids in the area in the visitors centre if you want to get more information. Let us begin by acknowledging the Traditional Custodians of the land on which we travel today, and pay our respects to their Elders past and present.
