From Oxford, follow Ashely Gorge Road for 6 km. Turn into Lees Valley Road and follow this for 29 km to a sign that indicates the vehicle track. Follow this marked track (it's generally negotiable with two or four wheel drive vehicles) for 3.5 km to a locked gate and car park. Keep to the marked track as this is private farmland.

Before you go, buy 1 Standard Hut Ticket (blue for adults, yellow for youth) for each night's stay. Put this in the honesty box at the hut. Or buy a Backcountry Hut Pass that gives unlimited use at most Standard and Serviced huts for a 6 or 12 month period.
