Cullen Bullen 8931-3N
This canyon is about 600 metres long and can be walked. Ropes or tapes are not needed.
In some places it is necessary to climb under obstructions, in other places you have to climb.
There are a couple of pools, one quite deep. There are some wide sections and some very narrow sections.
The exit portal is at the top of a cliff. It would be necessary to abseil and find a way back up through the cliff lines.
There is a hidden slot on the eastern side a short distance from the exit portal that can be climbed.
Sunnyside Canyon has also been known as Accoustic Canyon because of the sound in the canyon's larger chambers.
