Expensive and not worth it. Only 15 minutes on the tower and 30 minutes in a creek of the rainforest. The guide knew nothing about the rainforest and went away after the rainforest. And then a lunch at the Luquillo beach.
It was amazing...somewhat difficult heading back. It was hard when you had to pass by the boaters. They could be rude to us kayakers. But very much worth it. I would not say this for the beginner kayaker.
