Its nearest land being the Galapagos Islands, this unique volcanic mount far out in the Pacific Ocean has become famous amongst scuba divers for its schooling hammerhead sharks and other pelagic marvels. Visited only by live-aboard dive boats on seven-day cruises, the island has few disembarkation points and is uninhabited apart from some rangers. Legend has it that there is buried pirate treasure, but none has been found despite several search expeditions over the years. Only recommended for serious divers.
