Orient Bay, St Martin - The Saint Tropez of the Caribbean. Beach bars and a nudist resort keep this mile long stretch from getting boring
Grand Cayman - Seven Mile Beach. Despite the name, the beach is only about 5.5 miles long, all of which is built up with hotels
Negril, Jamaica - Vendors and jerk chicken are the diversions on this 7 mile long Caribbean strand
Varadero, Cuba - 12 miles of sand along a peninsula, not even a mile wide at its widest point. Tips: Possible salsa band sightings
Punta Cana, Dominican Republic - Seemingly endless stretch of beach and coconut palms, at least 30 miles long fronted by enormous resorts
Grand Anse Beach, Grenada - 2 miles of fluffy, golden sand along a sheltered bay
Harbour Island, The Bahamas - Pink Sands Beach. Solitude, tranquility and quiet are the hallmarks of this four mile long beach
Eagle Beach, Aruba - Miles of gorgeous, blazingly white sand. Watch the windsurfers zoom by
Horseshoe Bay, Bermuda - pink sand, framed by rocky coastline punctuated by sandy coves. Not officially Caribbean, but still rates an official tip
Luquillo Beach, Puerto Rico - Palm trees, hammocks, locals, snacks and miles of fine Caribbean sand and surf
There's a tacky tourist attraction in the town of West Bay on Grand Cayman that's called Hell -- and you might feel like you've been to the abyss and back once you see the throngs of bus tours ascending upon this place. Deliberately situated behind a souvenir shop (where the standard greeting is: How the Hell are you?) is a weathered limestone formation that ominously resembles the netherworld. Half the size of a football field, the dark, desolate, and torturously jagged site is said to be more than a million years old. The stone forest of Hell is best viewed from a platform overlooking this valley of, well, rocks. Versions abound on how Hell got its name, but the most likable is when a local official remarked "This is what Hell must look like" when he first saw the spot. The rest is history. So if you ever want to send a postcard from Hell (there's a post office here, of course) then this is your kind of place.
