We went to Dunn's River Falls as an excursion from Couples Tower Isle. This was great wet fun for all ages. While it is a 1000' climb up the falls, it was not difficult, and the climbers hold hands to make a human chain. If you have a serious physical problem, it is not for you, but we saw 5 year olds and 75 year olds making the climb. Swimsuits and water shoes are a must. The site is a national park, and there is a $20 admission fee to the falls unless you are doing it as a resort or cruise ship inclusion. The guides are very friendly and want you to have a good time. They will video you ($40) and take a still pic ($8). Skip the former but do the latter. There is a gauntlet of shops and vendors to run after you exit the falls. It was a must-do activity; when we got to the top we wanted to go back down and start all over again.
