An interesting and scenic loop along Glenbrook Creek and Kanuka Brook, returning via the Red Hands Cave Track. It includes a side-trip to the spectacular Crayfish Pool and Grey Hat Falls.
A great bushwalk for a hot day, Glenbrook to Lapstone along Glenbrook Creek offers countless swimming opportunities and some spectacular scenery. The optional and more challenging side-trip up to Mount Portal Lookout provides some great views.

A partly off-track route, this is a great bushwalk for a warm day. After descending the steep track (Tierney Track) from Pisgah Rock down to Erskine Creek, follow the downstream to the Jack Evans Track, which provides an easy route back up to the top.
