We went canyoning with these guys (Sabrina and Jean) a few years ago. It was excellent. They provide wet suits and helmets, and of course the harnesses and ropes. 4 of us, including some young teenagers, and another group with an age range from about 12 to about 70(!) all had a great explore of this amazing canyon - jumping, rappelling and swimming. Highly recommended. Once you're past the first waterfall (25 metres) it's easy! They make it safe and fun.
