Wild Abseiling is definitely for the more adventurous. It is presently the highest natural commercial abseil in the world at 110 meters.  The first 45m is a cliff abseil where one traditionally abseils with their feet against the cliff while the remaining 65m is a free abseil allowing one to take in the beauty of the gorge from a different angle. 

Beginners are welcome to abseil and will be given full instruction on the techniques and only when they have satisfied certain requirements will they be lowered over the edge of the 170m waterfall.  Qualified trainers are on hand to show one the ropes, so to speak.
