My 4 kids, ages 8, 10, 12 & 15 did the climb in Dunns River Falls and LOVED it!! I couldn't climb in the water so I went up along side of the falls. And there are places you can get out if it's too much for the kids. I posted a review of what I did on that stop, I'll try to locate it and repost it. Our tour guide was AMAZING!!
