Rangiroa in French Polynesia is one of the largest atolls in the world. Many narrow passages connect deep lagoon with an open ocean. The Tiputa Pass is the major entrance to the lagoon not only for ships, but above all for variety of fish species. The idea is to get underwater and observe different animals to pass by.
The dive site here depends on the current that is mostly unpredictable in advance. Once in the boat you will learn in which direction current flows. Is it a strong and dangerous outgoing current, or is it safer ingoing one that will drag you to the sand bar inside the lagoon?
