The main town is on the west side of the island. The east is largely uninhabited. We went out snorkling on a private speedboat the first day and got terribly burned. The water was beautiful though, and we saw lots of fish.
In town there were a bunch of bars and backpacker hotels. We had great food at a place called Barracuda (they eat a lot of barracuda around here) and had a surprisingly good protein bar made by a dutch hippy.
