Anegada, British Virgin Islands
A small airport and ferry service makes getting here from one of the other British Virgin Islands fairly easy, but Anegada still feels a world away. The only coral island in the volcanic BVI chain and surrounded by the largest coral barrier reef in the Caribbean, this undiscovered island is a haven for beach bums, fly-fishermen, and wildlife enthusiasts alike. The north shore boasts nearly deserted white-sand beaches, the south is home to a huge population of bonefish, and the west end lays claim to large salt ponds and exotic birds. Spend your nights feasting on local lobster – rumored to be the best in the Caribbean – and rest your head at one of the island's few hotels and quaint guesthouse inns.
Fakarava, French Polynesia
Overshadowed in popularity by neighbors Tahiti, Bora Bora, and Moorea, Fakarava – a pristine Polynesian island enveloped by a coral reef and blue lagoon waters – is so remote, it's not even found on most maps. Yet, it's part of a UNESCO nature reserve and rich in natural fauna, offers pink-sand beaches, and is rife with rare aquatic life that includes loach, meru, and barracuda – not to mention hammerhead and tiger sharks. Not surprisingly, scuba diving is the undiscovered island’s top draw, but other attractions include the ancient village of Tetamanu, where you’ll find a Catholic church made of coral that dates back to 1874, and pearl farms, where rare black pearls are shelled.
Lamu, Kenya
Kenya’s oldest living settlement, Lamu boasts golden sands fronting the Indian Ocean, tiny villages, and a breezy, slow-moving pace of life. It's an undiscovered island that offers a glimpse into the past – a place where donkeys are the main mode of transportation and residents still keep their arms and legs covered out of respect while out in town. The rich atmosphere and history alone makes Lamu worth the trek, but so do its beaches: Shela Beach offers the best swimming, while excursions to ruins and coral reefs could have you snorkeling alongside frolicking dolphins.
