Located in Fakarava Atoll, a UNESCO Biosphere Reserve, the Tumakohua Pass is famous for its “wall of sharks”, which attracts scuba divers from all over the world. For snorkelers, it is also a beautiful site to discover, both in the pass (which can be explored in drift snorkeling) and on the reef flat (which can be snorkeled freely from the island shore). In the area, you will discover coral reefs inhabited by Napoleon wrasse, blacktip reef sharks, and a myriad of colorful fish.
Tumakohua Pass and Tetamanu Island are located south of Fakarava Atoll, about 1h30-2h by boat from Rotoava and the airport. To visit Tetamanu, you can book a stay in one of the island’s guesthouses (Tetamanu Village, Tetamanu Sauvage or Motu Aito), or make the day trip from Rotoava (from euro 100pp.). The reef flat (zone 1 on the map) can be snorkeled freely from the shore. To explore the pass (zone 2 on the map), you’ll have to book a drift snorkeling tour. Do not attempt to explore the pass without being accompanied by a guide.
To snorkel the reef flat, water entrance is made from Tetamanu island’s shore, taking care not to step on coral. For drift snorkeling, you will enter the water from your tour boat.
Two areas are recommended for snorkeling around Tetamanu:
Three guesthouses (Tetamanu Village, Tetamanu Sauvage and Motu Aito) are set up along the reef.
These snorkeling spots are accessible to beginners and kids. You will enter the water gradually from a beach, or in a less than 3ft. deep area. The sea is generally calm, shallow, with almost no waves or currents. These spots are usually located in marked and/or monitored swimming areas. It is not necessary to swim long distances to discover the sea life.
This level only apply when the spot experiences optimal sea and/or weather conditions. It is not applicable if the sea and/or weather conditions deteriorate, in particular in the presence of rough sea, rain, strong wind, unusual current, large tides, waves and/or swell. You can find more details about the definition of our snorkeling levels on our snorkeling safety page.

Snorkeling spots are part of a wild environment and their aspect can be significantly altered by weather, seasons, sea conditions, human impact and climate events (storms, hurricanes, seawater-warming episodes…). The consequences can be an alteration of the seabed (coral bleaching, coral destruction, and invasive seagrass), a poor underwater visibility, or a decrease of the sea life present in the area. Snorkeling Report makes every effort to ensure that all the information displayed on this website is accurate and up-to-date, but no guarantee is given that the underwater visibility and seabed aspect will be exactly as described on this page the day you will snorkel the spot. If you recently snorkeled this area and noticed some changes compared to the information contained on this page, please contact us.

Remember that all marine activities, including snorkeling, are potentially dangerous, and that you enter the water at your own risk. You must take an individual weather, sea conditions and hazards assessment before entering the water. If snorkeling conditions are degraded, postpone your snorkeling or select an alternate site.
