My husband and I booked the night before and they were so accommodating. Our guide Lisa was amazing. Seriously. So full of information. The kayak portion is beautiful and tranquil. She tried very hard to keep us off the beaten path. The walk to the falls was challenging but well worth the effort to see the falls. Make sure you swim right up to it. So exhilarating. Then we had a little snack and were serenaded by a beautiful drum that Lisa brought in with her. As far as I am concerned this is one of the best experiences for the money imaginable.
