For very serious hikers this may not be your cup of tea, but for a beautiful walk through the woods alongside a beautiful river with gorgeous waterfalls some of which (5/8) you'll swim in, this is a worthwhile excursion. Lunch is delicious, the people are really friendly, you can relax in Adirondack chairs under some trees and watch alligators and flying toucans and macaws. It is a perfect half day excursion with lunch. If you want to do a full day, add a horseback ride. I preferred this excursion to "Rio do Peixe" because fewer people were grouped together, the surroundings were spectacular and the infrastructure is a little better. Our guide took pictures of us with his underwater camera and sold us a CD later. You are not at all obliged to pose for photos nor buy the CD, but the pictures turned out great so we were happy he did this. My daughter had an allergic reaction to a bug bite and he had an (over-the-counter) anti-allergy cream at a mini first-aid post along the trail. That was excellent. You will have a mini-boat ride and see animals along the way. I absolutely loved it. Since some of the excursions in Bonito are more tiresome, choose this one on a day that you want to balance your trip out with something more leisurely. It was so scenic and serene. (In the morning we had gone tree top walking and innertubing so the combination of adrenalin in the morning and this nature walk in the afternoon made for a splendid day.)
