This was an adventure for sure. The kayaking part was rigorous, as well as the mile hike to the falls, but we did it, and we felt good for the accomplishment. The falls are incredible! Be sure to wear water/reef shoes on this trip. Some folks had high end sneakers which were pretty trashed at the end because we were walking through water etc. The suggestions for this tour said no crocs, yet people wore them and regretted it. Alan, our guide, was kind, thoughtful and very knowledgeable about plant life and the island in general. We recommend this tour for people in good physical shape.
