The largest and most visited atoll in the Tuamotus, Rangiroa is, in fact, among the largest atolls in the world. It lies 185 mi/300 km northeast of Papeete. It consists of approximately 240 thin motu, or islets, that completely surround an enormous lagoon measuring 42 mi/67 km long by 14 mi/22 km wide. The name Rangiroa comes from a Polynesian word that means "huge sky," and that's appropriate. The expanse of blue sky and blue water dominate. Any land you see is flat and covered by palm trees.Subscribe to travel42 to read the full Destination Guide. travel42 offers professionally written guides on more than 5,700 travel destinations and ports-of-call worldwide.
