This is the third time we have gone to Eden Rock. it's only about 1000 feet to the right of the main pier at Georgetown. The first dive/snorkel shop is not as good, so be sure to go to the 2nd dive shop which is Eden Rock Diving Center. Our son and his friend took a "refresher" scuba class with Chris and he was an excellent instructor. My wife and I just snorkeled this time. The water was amazingly clear with sea turtles, tarpon, silversides and all the beautiful small tropical fish. For snorkeling all you need is a locker there ($5) to store your stuff. There is Eden Rock and a little farther is Devil's Grotto which is very good for scuba diving. Well worth while.
