David Crevasse is a dry canyon accessed via the Mt Banks picnic area. There is a long but picturesque walk (6kms) along the ridge to get there. There are 6 abseils and then on the walk out from the canyon a prussick of around 8 metres to get back to the track out. You need to be confident with prussicking to come on this trip. There will be a limit of 6 participants.
