Fakarava is the second largest atoll in the Tuamotus. The environment here is so pure that it has been named a Biosphere Reserve by UNESCO. There are two passes in Fakarava. The huge Garuae Pass in the northern end is more than 1/2 mile wide, while the Tumakohua pass in the southern end measures only 200 yards. Yet both passes serve as a meeting place for all sorts of marine life including Gray Sharks, Leopard Rays, and Barracudas. Book your trip June-July and you're likely to see huge schools of groupers gathering in the pass to reproduce. Fakarava is a true diver's paradise!
