Bora Bora is a small South Pacific island northwest of Tahiti in French Polynesia. It is surrounded by sand-fringed islets and a turtquoise lagoon protected by a coral reef, and it's known for scuba diving. It's a popular luxury resort destination, and some guest bungalows are perched over the water on stilts. At the island's center is Mt. Otemanu, a dormant volcano.
