TravelTalkOnline Forums Travel and Vacation Forums St. Maarten - St. Martin BVI cruisers trying something new

We usually do our crewed catamaran vacation in BVI but have decided to try out St. Marteen/St. Barts/Anguilla route this June. Any suggestions on what are the must see beaches, snorkel spots or just anything else we don't want to miss? Any information would be appreciated.
