This is a fairly short canyon on the south side of the Wollangambe at Mt Wilson. There are 6 abseils up to about 20m, one with a slightly awkward start. It is a wet canyon with some swims, an optional jump, and some small waterfalls to negotiate. So you must be able to swim and be comfortable abseiling in a waterfall. We end up in the Wollangambe where a short wade up stream or scramble on the bank takes us to the exit track. Wetsuits required.
