Starting from the Sullivan Rock car park on Albany Highway, Mount Cooke, this walk takes you past Sullivan Rock to the summit of Mount Cooke and back via the Bibbulmun Track. One of the best sectional day walks in the area, this hike leads walkers from the granite formation known as Sullivan Rock to the summit of Mount Cooke, the scarp's highest peak. A campsite is located at the base of Mount Cooke, making this also a good option for an overnight walk. The hike to Mount Cooke begins with a walk right up the middle of Sullivan Rock. There are cairns alongside the track which can be used for navigation, with moss and Gnamma scattered around. Once over the rock and down amongst the jarrah trees, you'll reach the junction where the Bibbulmun Track begins. The track continues through low-lying jarrah and sheoak forest on flat ground, with the trees eventually thinning out into a swampy floodplain area. A noteworthy landmark along this stretch is an old rusty car sitting upside-down on the side of the track. The forest becomes increasingly dense and the track starts to incline slightly as it approaches the Mount Cooke Campsite. If you've decided to stay the night, you can set everything up and leave it at the campground before going for the summit walk. From the campsite, the track climbs steeply towards the summit of Mount Cooke, with some nice views to the east. After exploring the summit and enjoying the views, you can return via the same route or choose to continue following the Waugal markers and rock cairns down the southern slope of Mount Cooke. If you are lucky enough, you might even find the elusive Mount Cooke Cave and have a chance to leave a note in the 'Cave Book'. This is a relatively long and challenging walk, suitable for walkers with a moderate level of fitness and experience. The track is generally easy to follow, with the Waugal markers providing clear directional information. The terrain is mixed but the majority of the hike is quite gentle, with a few rocky sections and some manageable ascents and descents. Sullivan Rock and Mount Cooke are largely made of granite, so extra care must be taken in wet and slippery conditions. 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.
