French Polynesia guide

Snorkelling in French Polynesia

Snorkelling is the heart of this destination and it does not require experience. Society Island lagoons are calm, shallow and warm, with reef fish, rays and turtles visible in waist-to-shoulder-deep water. In the Tuamotus, guided drift snorkelling in the passes brings sharks and larger fish within easy view. Water is warm enough year-round that most people need no wetsuit.

Lagoon snorkelling

The lagoons are the easy half. Shelter from the reef keeps the water calm, depths are modest, and visibility is usually good away from run-off. You can float above coral bommies watching parrotfish and butterflyfish without ever being out of your depth.

This is where nervous or out-of-practice swimmers get comfortable. Guides here are used to beginners, and most ships run a shallow, sheltered first session before anything more demanding.

Drift snorkelling in the passes

In the atolls the interesting water is in the passes, and the technique is to enter on the incoming tide and let the current carry you in while a boat follows. Done properly it is effortless — you are not swimming so much as flying — and it puts you above the concentrations of fish and sharks the Tuamotus are known for.

Done at the wrong state of tide it is unpleasant or unsafe, which is why the timing belongs to the guide. See the Tuamotus for how the passes work.

What to bring and what ships provide

Most vessels provide mask, snorkel and fins, and many carry shortie wetsuits or rash vests. What we tell clients to bring anyway: their own mask if they have one that fits, reef-safe sunscreen from home, and a long-sleeved rash guard, which handles sun better than sunscreen ever does.

Sun is the real hazard here, not the wildlife. An hour face-down in the water with a breeze on your back is exactly how people get badly burned.

Common questions

Do I need to be a strong swimmer?

For lagoon snorkelling, no — buoyancy aids are available and the water is shallow and calm. For pass drifts you should be comfortable in open water and moving current, and the guide will tell you honestly whether a given site suits you.

Is the water cold?

No. It is warm year-round and most people snorkel in a rash guard or nothing more. Repeated long sessions can still chill you, which is why ships carry shorties.
