YS Falls Falls are in the south of Jamaica, part of Saint Elizabeth town at the mouth of the Black River. The name comes from the initials of the former owners of the farm close to the falls. They were opened to the public in 1990. In my opinion, it is the best natural attraction in Jamaica, as it is the most fun. You can do action sports, such as ride on the zip line, jump natural targets ( Tarzan type)and jump waterfalls. There are seven waterfalls in total, but what I liked best were the natural pools, one of which was also suitable for children or for people who cannot swim.
