We spent one day on our Puerto Rico vacation on Altura's Waterfall Adventure. It was hands down the best thing that we did on our trip. Hector and Andre were outstanding guides. They were knowledgeable, and despite the "thrill" of the day, we always felt safe. They also do a great job of capturing pictures for you to share with your friends. The adventure included rappelling down three different waterfalls... a once in a lifetime experience. We wrapped up our day with lunch home cooked by a local friend. I HIGHLY recommend doing this!
