Where to go snorkeling on Réunion Island.

Why the west coast is best for observing the seabed

To fully enjoy snorkeling on the island, head for the west coast: that's where the lagoon is most often calm, where the coral reef plays its protective role, and where the water is clearest (good visibility) when conditions are right. Between Saint-Gilles, L’Ermitage, La Saline and Saint-Leu, there are shallow areas ideal for spending long time with little effort, with reef fish very present near coral bommies. Conversely, the east and the wild south are more exposed to swell, wind and currents: beautiful, but rarely suitable for a relaxed mask-and-snorkel outing.

Before entering the water, make a habit of observing the surface: chop, current lines, darker areas (depth), and identify an easy exit point. The right instinct is to enter the water in authorized, sheltered areas, then follow the shore calmly rather than heading offshore.

The must-see spots in the lagoon (Saint-Gilles / L’Ermitage / La Saline)

The trio Saint-Gilles – L’Ermitage – La Saline concentrates the most accessible sites: beach, gradual entry, shallow areas, and abundant marine life. You will often see butterflyfish, damselfish, surgeonfish, wrasses, and sometimes giant clams or sea urchins hidden among the rocks. The advantage is being able to adapt the outing to your level: stay in 1 to 2 meters of water for a first discovery, or move a little farther (always cautiously) to deeper areas to vary the observations.

The best times are generally early in the morning, when the sea is calmer and the low light better reveals the relief. Around midday, the wind can pick up and disturb the surface: this does not necessarily make swimming in the lagoon dangerous, but observation becomes less pleasant.

Saint-Leu: a lively lagoon and areas to explore methodically

Further south, Saint-Leu charms with an often more natural vibe, featuring very nice stretches of reef and areas where wildlife is active. The key here is to choose a simple launch point and remain attentive to conditions: depending on the season, wind and swell can transform the experience. When everything lines up, it’s an exciting spot for those who enjoy observing transitions between sand, seagrass and coral.

Rocky areas and sheltered coves: perfect for seeing things differently

In addition to the large lagoon beaches, some rocky areas, small coves or sectors with alternating sand/rock can hold great surprises, especially when the sea is calm. You may sometimes observe more micro-diversity there: small hidden fish, shrimps, crabs, anemones, and attached life (algae, sponges) that give the coastline another face. The advantage is that these places are sometimes less frequented, but that means being even more rigorous about safety: entering/exiting the water, slippery rocks, unexpected waves.

Essential tips: safety, weather, regulations and respect for the reef

On Réunion, a successful outing depends as much on the spot as on common sense. Here are the fundamentals to take on board:

1) Check conditions before you leave : even in the lagoon, unusual swell, sustained wind or very dirty water should make you postpone the outing. Visibility is a good indicator: if you can’t see the bottom near the edge, observation will be limited and the experience less relaxed.

2) Enter the water in suitable areas : favor places where the entry is gradual and the exit easy. Avoid passes, breaking-wave zones and areas where the current can concentrate.

3) Never touch the coral or stand on it : coral is alive and fragile. A simple touch can hurt it, and a fin strike can break structures that took years to form.

4) Fins: yes, but with control : keep a flat kick, fin gently, and maintain a safe distance above the bottom. Many impacts come from poor fin control, especially when getting closer to look at a fish.

5) Sunscreen: choose a more respectful formula : if possible, opt for a more reef-friendly protection and complement with UV-protective rashguard. Less product in the water, more comfort, and often fewer sunburns.

6) Observe without pursuing : if a turtle, a parrotfish or a school drifts away, let it go. The best scenes happen when you stay discreet, in passive buoyancy, breathing calmly.

What can you see underwater? Fish, corals, turtles… and surprises

The Réunion lagoon offers a very photogenic palette. Reef fish are the most common: damselfish in clouds, butterflyfish often in pairs, grazing surgeonfish, colorful wrasses, and sometimes denser schools along the bommies. With a bit of luck (and especially by staying calm), you may see a turtle come up to breathe or feed farther away. Magical moments often happen when you slow down: stop, float, look into holes and under overhangs.

Beyond the stars, you can observe fascinating behaviors: cleaner fish working around other species, small predators lying in wait, or rapid color changes in some fish. Bringing a well-fitting small mask and taking the time to anti-fog it properly really makes a difference: more comfort, more observation time, therefore more discoveries.

Recommended equipment: simple, but well chosen

No need to over-equip, but a few details make the difference:

Mask : fitted to the face (test the seal without the strap), clean lens, comfortable skirt. A leaking mask ruins the experience.

Snorkel : a simple model works very well. A comfortable mouthpiece is more important than gadgets.

Fins: they reduce fatigue and increase safety (easier return to shore). Choose the correct size, without pressure points. Booties: useful if entry is on a rocky area or if you walk on sand with coral debris.

Lycra / shorty: protects from the sun, minor irritations and allows you to stay longer in the water. When to go: seasons, times and ideal conditions.

The best windows are those when the sea is calmest and visibility most stable. Early in the morning the water is often smoother and the light brings out the colors. Depending on the season, the water can be warmer and attract more activity, but this can also coincide with more changeable weather. The important thing is to judge actual conditions rather than the calendar: if the sea is calm, visibility is good and you feel safe, you have the winning trio.

Les meilleures fenêtres sont celles où la mer est la plus calme et la visibilité la plus stable. Tôt le matin, l’eau est souvent plus lisse et la lumière met en relief les couleurs. Selon les périodes, l’eau peut être plus chaude et attirer une activité plus marquée, mais cela peut aussi coïncider avec des épisodes météo plus changeants. L’important est de raisonner conditions réelles plutôt que calendrier : si la mer est calme, que la visibilité est bonne et que vous vous sentez en sécurité, vous tenez le trio gagnant.

Itinerary ideas: alternate between the lagoon and the island's vast landscapes

One of the great pleasures on Réunion is following a morning in the water with an afternoon in the highlands. After a snorkel outing, you can switch to more land-based activities without hours of driving, varying the atmospheres: sunlit coastline, humid forests, dizzying viewpoints, waterfalls, cirques. This alternation also helps you recover better: if the sea is less favorable one day, you always have a spectacular plan B.

Plan your stay well: where to stay to explore easily

To maximize outings in the lagoon without spending your time in the car, the ideal is to stay at a reasonable distance from the west beaches and the easiest launch points. This way you can pick your time slots according to the weather (go out early in the morning, come back, leave again later) and improvise as soon as the sea becomes perfect. If you are looking for a convenient base to plan your days, you can consult Our Seasonal Rentals in.

Final checks for successful outings

Stay humble before the ocean: if conditions worsen, postpone. Swim with a companion when possible, or inform someone of your return time. Bring water, a towel, and something to protect you from the sun. Finally, favor respectful observation: keep your distance, do not take anything, do not feed. It’s the best way to enjoy the island’s most beautiful underwater scenery for a long time, outing after outing.
