These guys are wonderful - it's safe, fun and great for all ages (Our group had 10-74 and some fear of heights!!!) Highly recommended for an afternoon off from the beach. Wear your bathing suit - you can go swimming in the top waterfall! Also, there is quite a lot of climbing of stairs, windy paths etc. so you need to be reasonably fit, but certainly it isn't arduous. They also take really good pictures AND shoot video of everybody which means that, if you're the family photographer like me, for 20C you can leave the darned camera at home and enjoy yourself!
