Around to the outside of Antigua Nonsuch Bay's reef provides some beautiful snorkeling if the swells not too high. The anchorage at Green Island (Ricketts Bay) nearby is small and fairly private, and also nearby is Ten Pound Bay, with a gorgeous beach and no crowds except for the noon arrival of the occasional rum charter. Ten Pound can be tough to get into and is a bit shallow so getting in depends on weather and your boat.
