Pleased we took this adventure. One of us is just over 60 years old and the other just under. We are moderately fit and active. Can’t see us doing it 5 years on. The falls remain closed due to typhoon damage, so we spent 4 hours jumping off cliffs and traversing slippery hillsides. We had our own water shoes, but the company can supply you with suitable shoes if required. We saw people from other tour providers wearing flip flops, slides, and even high heeled rubber sandals (no thanks). We had 8 guides for approximately 26 people. An excellent ratio, allowing the guides to be attentive and aware of the needs of each guest. They were there to help us cross slippery rocks, jump off cliffs into the deep water section and take videos on our go pro. We felt safe knowing the guides were watching out for our safety. They even caught my partner as she was floating down steam about to go over a small waterfall that was not the recommended route.
