About this place
What to expect
Claustral Canyon is a difficult 700 metre canyon near Mount Tomah, in the Mount Wilson area of Blue Mountains National Park. Allow about 10 hours for this challenge, which includes a total walk distance of 9 kilometres. Be sure to come to this technical canyon prepared for three abseils, down-climbs, lots of scrambling, and jumps. There are also multiple swims, including a 50 metre long one that's known as the tunnel swim'. Because you'll be spending a fair amount of time in the cold waters of Claustral Brook, summer is the best time to attempt Claustral Canyon. The access track to Claustral Canyon starts from a large pull-in area on Bells Line of Road, just south-west of Mount Bell. Follow the signposted formed track towards Claustral Brook and the gully where the canyon begins. Take extra care when exiting the canyon because the exit gully is easy to miss.
