I had a visiting friend (63) decide she wanted to try rafting. I was worried it might be too strenuous and I had not been rafting in over 35 years. On the phone it was recommended that we wear the wet suits they provide. There were 4 in our group, and normally I would feel strange wearing a wet suit, but since the woman on the phone highly recommended it, and the weather was unseasonably cool, we all wore them. It made the trip very comfortable, and the level of paddling was strenuous at points, but very do-able, even with the achy joints that come with age. Our guide, Sebastian, was calm, pleasant, and informative. We could not ask for better.
