Tiputa Pass

Tiputa · Tuamotu Archipelago · French Polynesia

Tiputa Pass is the crown jewel of Rangiroa, the second-largest atoll in the world, and one of the most exhilarating drift dives anywhere on Earth. Situated between the villages of Tiputa and Avatoru in the Tuamotu Archipelago, this deep ocean pass connects the vast lagoon of Rangiroa to the open Pacific, funnelling immense volumes of water and marine life through a narrow gap in the atoll rim. The signature experience here is the incoming drift dive. Operators time the descent to catch the flood tide, and divers are swept from the ocean side through the pass and into the lagoon at speeds that can feel like flying. Along the way, the walls of the channel teem with grey reef sharks, sometimes numbering in the dozens, while large schools of barracuda, trevallies, surgeonfish, and tuna create a swirling wall of silver. Napoleon wrasses patrol the reef edges with regal indifference, and whitetip reef sharks rest in crevices along the bottom. But Tiputa Pass truly earns its legendary status between January and March, when great hammerhead sharks arrive to hunt eagle rays. These magnificent predators, some exceeding four metres in length, cruise through the pass in the early morning hours, and encounters with multiple hammerheads on a single dive are not unusual. Bottlenose dolphins are year-round residents, and divers often hear their clicking and whistling before the sleek grey shapes materialize from the blue. Manta rays make regular appearances as well, particularly during plankton-rich months. The pass reaches depths well beyond recreational limits in the centre, but most dives are conducted at 25-40 metres along the walls before drifters ascend into the shallower lagoon. Visibility typically ranges from 20 to 30 metres, though plankton blooms can reduce it. Water temperature stays between 26 and 29 degrees Celsius. Given the powerful currents and depth, this is firmly an advanced dive, and choosing a reputable operator with deep local knowledge of the pass's moods is essential for both safety and the best encounters.
