Concierge.com's insider take:
A visit to Bequia, blessed with the type of crystal-clear waters from which a thousand clichés are born, would be a sin without a dive under its translucent waters. The island is home to numerous PADI-certified dive shops, many of which provide one-day courses for curious novices. Bequia Dive Adventures offers up to a dozen different kinds of diving courses; it also arranges weeklong vacations, including hotel accommodations (784-458-3826; www.bequiadiveadventures.com). Another option is Dive Bequia, whose Yankee owners, Bob Sachs and Cathy Howard, organize weeklong diving holidays in partnership with top local hotels (784-458-3504; www.dive-bequia.com).
