Fodor's Expert Review Bioluminescent Bay

Grand Cayman's bioluminescent bay, near Rum Point, is one of the few such bays in the world. It's about 45 minutes from George Town and can be visited on a guided tour. The bioluminescent dinoflagellates are visible for a couple of weeks every month, but not at all times. The local tour operators know the best times to visit and schedule tours for those nights (especially when there is no full moon).
