Ureparapara is one of the most worldwide singular island. The island is an old volcano whose part of its foots-hill has collapsed occasioning the immersion by sea of the caldera. The old caldera is today a 2 miles deep bay where sailing boats stop from time to time. There is no regular maritime lines , no plane. The closest island can be reach after a two hours power boat sailing trip. There are three small villages with a total of around 450 inhabitants who welcome warmly the infrequent visitors. Léar, also named Leserepla, the main village, is located at the bottom of the deep Divers bay. Way of life seems similar to that of centuries ago. A description of Ureparapara and its Divers (Dives) bay has been consigned in Captain Bligh logbook during his Pacific cross-over trip after he has been disembarked, when leaving Tahiti, from the UK flag Bounty, further a mutiny , at the end of 18th century.
