Fodor's Expert Review Captain's Bay

On the north coast just before the eastern tip of the island, this quarter-mile stretch of perfect white sand is bounded by a rocky shoreline where Atlantic waves crash. If you make the tough, four-wheel-drive-only trip along the dirt road that leads to the northeastern end of the island toward Junk's Hole, you'll be rewarded with peaceful isolation. The surf here slaps the sands with a vengeance, and the undertow is strong—so wading is the safest water sport. Amenities: none. Best for: solitude.
