Just offshore, the little islet known as Sandy Cay is a gleaming sliver of white sand with marvelous snorkeling and an inland nature trail. Previously part of the private estate of the late philanthropist and conservationist Laurance Rockefeller, the Cay recently became a protected area. You can hire any boatman on Jost Van Dyke to take you out; just be sure to agree on a price and a time to be picked up again. As this is a national park, visitors are asked to "take only photos and leave only footprints." Nevertheless, it's become an increasingly popular location for weddings, which require approval from the BVI National Parks Trust. Experienced boaters can rent a boat or dinghy to go here, but be aware that winter swells can make beach landings treacherous. Amenities: none. Best for: walking; snorkeling; swimming.
