Running along the centre of the biggest urban area in the south of the island, Saint-Pierre beach opens onto a lagoon that is sheltered from the turbulence of the Ocean. Although it does not have the reputation of the Hermitage lagoon, it is at a very similar level and makes an excellent spot for snorkeling. After less than two minutes in the water, you will be swimming among a wide range of fish and invertebrates in a spectacular coral setting.

How to get to Lagon de Saint-Pierre snorkeling spot?

The beach is on the Saint-Pierre sea front, just next to the marina. From Saint-Denis, head south and follow the signs to Saint-Paul for 50 miles (80km), then Saint-Pierre (expressway for the entire journey, around 1 hour). Once you arrive at Saint-Pierre, there are many places to park near the beach: next to the road along the sea front, in one of the car parks behind the beach or in the marina car park.

Once at the beach, find the marina dyke, to the left when you are facing the ocean, and enter the water nearby. Saint-Pierre train station, where the buses in the Car’Jaune and Alternéo networks arrive, is less than 5 minutes from the beach on foot.

Entering the water in Lagon de Saint-Pierre

You can enter the water anywhere along the beach, but you should choose the bathing area (shown by small buoys), which is cleared of the lagoon’s sea urchins every day. The 200 to 300 meters of beach stretching away to your right (as you are facing the ocean) from the marina dyke is probably the most interesting spot for snorkeling.

Snorkeling tips while exploring Lagon de Saint-Pierre 

The area to explore covers the inner part of the lagoon, from the beach to the barrier reef.

The first few metres from the beach are sandy (↕2-4ft/0.5-1m), with a few fish here and there, including Picasso triggerfish, which fiercely protect their nests during the reproduction period.

You need to go a little further to reach the coral areas (↕2-6ft/0,5-2m). You will never tire of swimming between the acropora beds, following one of the Moorish idols, pufferfish or raccoon butterflyfish you are likely to meet. Among the most colourful species in the lagoon, it is not unusual to come across the clown coris (a familiar sight in aquariums) or the spectacular Meyer’s butterflyfish. Have a good look at the coral beds: many giant clams, moray eels, octopus and coral shrimp lodge in the crevices.

The exquisite -but discreet- clown coris can sometimes be seen on the reef.

The closer you get to the barrier reef, the denser the coral becomes, until it prevents you going any further. In any case, you should not try to, since the barrier reef and the depth of the water generally make it impossible.

The predominant coral in the lagoon is the branching acropora type. They are spectacular, but also very fragile, and can break at the slightest touch of a swimfin. Be careful as you move forwards, especially if you go through narrow or shallow passages.

Parrotfish at Saint-Pierre, Réunion Island
The blue-barred parrotfish is very common in the shallow parts of the lagoon.

It is possible to explore the lagoon most of the time, since the waters are particularly well protected. In winter, the wind results in waves that may make your return more difficult. Saint-Pierre beach is lifeguarded during the day. Ask the lifeguards if you have any doubts about water conditions.
