Eat, wander, shop, snorkel, admire views, visit and drink in an atmosphere that makes AC seem like a teeming metropolis...oh, and with any luck, not get on the wrong return water taxi or miss the return water taxi completely. There are also chartered day trips with snorkeling stops on the way. I agree it is well worth the visit. You can find lots more info on this board or by googling Caye Caulker.
