Green Island, Antigua On one of the four dreamy stretches of beach, you'll find few friends other than the small, shy, green iguanas. Walk through the brush to the 40-foot coral cliffs and spy on the fish-filled reefs below.
Sandy Spit, British Virgin Islands Used as a backdrop for countless movies, Sandy Spit satisfies every version of the shipwreck fantasy. Once you've acted them all out, breeze over to the south side and snorkel along the reef.
Monkey Island, Jamaica Swim over sandy channels from tranquil San San Beach to this island outpost. Once ashore, climb 100 feet up via well-positioned tree roots to take in views over the green hills of Jamaica all the way to Cuba.
