You've got 140km of stunning hiking right on your door step with the cape to cape track. The track traverses along the ridge and beaches of the Leeuwin-Naturaliste National Park following the coast from Cape Naturaliste, Dunsborough to Cape Leeuwin, Augusta. With a bit of logistics management, you can choose different sections to do in a day, or otherwise just drive 2kms for the Surfers Retreat down to river mouth and do some out and back walks. 

There are other beautiful walks in the Boronup Forrest and Meelup reserve up in Dunsborough.
