Is Seychelles Good for Snorkelling? Honest Guide for 2027 (Sites, Season, Coral)

Yes, Seychelles is good for snorkelling, with caveats. Start at a sheltered shore bay on a calm day, add one marine-park boat trip, and buy the SPGA ticket online. The water is warm all year and, by most guides, calmest in April–May and October–November. Coral is thin: about 14% live hard coral nationally in 2025, per a SeyCCAT report.

I would go for the water, the granite boulders and the turtles. I would not go expecting a Great Barrier Reef.

What is the snorkelling actually like?

Expect fish, granite and the odd turtle more than a coral garden. The SPGA says Ste. Anne is "a perfect snorkeling spot", with many coral types and green turtles feeding over seagrass. That is a fair summary of the inner islands.

The brochures call every bay a snorkeller's paradise. Some are. Others are a lovely beach with a murky strip of sand, so the month and the side of the beach matter more than the island.

Why shore snorkelling can disappoint

Seychelles shore snorkelling is bay by bay, not a reef you walk into. SeyVillas says that outside the calm months waves and currents reduce visibility at Sunset Beach. Enriching Pursuits found Anse Lazio clearer on one side and unsafe in waves (details below). In my judgement, a calm bay with a patch of rock is often better than a long sandy beach. That is an opinion, not a measured rule.

A boat trip to a marine park gets you to a reef that is protected and chosen for snorkelling. A Seychelles marine-life guide on Koek says turtles, small rays and reef fish can be seen from the surface in 2–4 m of water. Koek adds that the granitic reef complexity "starts at 10 metres and gets better as you go deeper", below snorkel depth.

What will you actually see?

Turtles and reef fish are the safe bet. Rays and sharks are luck.

• Turtles: the SPGA says green turtles feed on the seagrass at Ste. Anne. Koek calls hawksbill and green turtles "the most reliably encountered megafauna" and puts green turtles in the seagrass around Curieuse.
• Rays and sharks: Koek says small rays rest on sand in lagoons and seagrass, and whitetip and blacktip reef sharks are common around the islands. Treat any single sighting as luck.
• Whale sharks: seasonal and not a shore thing. The SPGA calls Port Launay "famous for its whale shark sightings". Koek puts the main window at August to October, peaking in September, particularly around the Amirantes and the northern tip of Bird Island, so plan on an organised trip.

What state is the coral in?

The reefs are recovering slowly and are still well below their old state. The national report is Status and Trend of Seychelles Coral Reefs: 2026. Barret and Gendron wrote it for the conservation trust SeyCCAT, and it was launched on 26 May 2026. It says: "The overall national trend in live hard coral cover is declining."

Here is what it and the other sources say:

• National mean live hard coral cover: about 14% in 2025. Cover fell sharply in 2016–2017, partly recovered after 2018, then went down again after 2023.
• Inner Islands (the islands around Mahé, Praslin and La Digue): around 20% in 2025, well below pre-2016 levels (GCRMN). SeyCCAT says the 1998 heat event cost an estimated 90% of live coral there, leaving about 3% cover.
• The report calls 2024 the most severe thermal-stress year in the available record. Seychelles was hit as part of the fourth global bleaching event, which NOAA confirmed on 15 April 2024. NOAA experts now say it likely ended in mid-2025, after about 84% of the world's reefs had faced bleaching-level heat.
• Aldabra, an outer atoll, fell sharply to around 14% cover in 2024 (GCRMN).

The report is cautiously hopeful. It says many reefs returned towards coral-dominated states after the 1998 marine heatwave, with recovery favouring deeper, structurally complex reefs. I could not find a published 2024 recovery figure for individual snorkel spots. So treat any "pristine reef" claim in a brochure as unproven.

When is the best time? Season by site type

April–May and October–November are the calmest, according to most guides. SeyVillas narrows it to April and November, with the south-east trades from May. In those gaps the wind drops. SeyVillas says visibility is at its best in April and November and "slightly reduced" otherwise. The table is the desk's reading of how each site type behaves, built from those sources. It is not measured data.

Season	Shore beaches (Mahé, Praslin, La Digue)	Marine-park boat trips (Ste. Anne, St Pierre)	Outer islands
April–May (calm; the trades may start in May)	Usually the calmest window. April is one of SeyVillas's two best months.	Usually good; flat water makes the crossing easy.	Usually a good window; check the wind in May.
June–September (south-east trades)	Hit and miss. Koek's beach guide says south-facing beaches get rough in the south-east trades, while north-west-facing Anse Sévère is sheltered. Sources disagree on a general rule, so check each beach's aspect and ask locally.	Doable on lighter days; the crossing is the weak point, not the reef (my judgement).	Wind-dependent, so build in spare days.
October–November (calm again)	Usually calm, like April–May. SeyVillas rates November among its best months, with Sunset Beach (north Mahé) and Anse Soleil.	Usually good, like April–May.	Usually good; check the wind.
December–March (north-west monsoon)	Pick sheltered bays; guides disagree on which coast is calm, so ask a local the same morning.	Good on calm days; rain and swell vary.	Check wind before you commit.

Scroll sideways for more columns.

Two limits to the table. First, no official source I found grades snorkelling month by month. Second, guides disagree on the north-west season, so ask on the beach. SeyVillas, for one, says that outside April and November "waves and currents reduce visibility and make swimming more difficult" at Sunset Beach.

How warm is the water, and how far can you see?

Warm, and clear enough to enjoy on a calm day. The numbers are soft, because I found no official dataset.

• Temperature: SeyVillas says the sea stays at "around 26 °C" all year. Its own table for Mahé and Praslin is more varied. It shows roughly 27–28 °C from December to April and 25–26 °C in May, October and November. June to September drops to about 23–25 °C. I would plan on warm water and pack a thin rash vest for long sessions in the cooler months.
• Visibility: I found no official figure. One French-language guide, Sailoe, says up to about 30 m in the best months. It cites no source, so treat that as the best case on a calm day. SeyVillas gives no metres either: it says visibility is "slightly reduced" outside April and November.

Shore, boat or outer island: which to pick?

For a first trip, start at the shore on a calm day and add one marine-park boat trip. Outer islands are for a second trip, or for people who already plan a liveaboard or resort stay there.

• Shore. Free, flexible, weather-dependent. Anse Lazio on Praslin shows why: Enriching Pursuits (updated June 2025) says the left side has much better visibility on a calm day. It calls the beach unsafe when waves are up.
• Marine-park boat trips. The reefs are protected, and the trips handle the sea for you. The SPGA says St Pierre islet, five minutes by boat from Curieuse, "offers wonderful snorkeling and diving". Port Launay on Mahé's north-west coast is a marine park you can also reach by road, with reefs "on both sides of the bay".
• Outer islands. GCRMN calls the Alphonse Group "the strongest coral-cover system in the dataset". It adds that this is spatially uneven and needs longer, denser monitoring. The logistics (flights, liveaboards, resort-only access) are a trip in themselves.

I would skip the shore beaches on a windy afternoon and wait for the morning, when the sea is usually calmer. That is my judgement, not a sourced rule.

Which island should you base yourself on?

Pick Praslin for the water and Mahé for choice. This is my judgement, not a ranking from a source.

• Praslin: Anse Lazio for calm days, and the natural base for a boat day to Curieuse and St Pierre.
• Mahé: the most bays, and Port Launay is a marine park you reach by road. The SPGA gives the drive as 30 minutes from Victoria.
• La Digue: I have no sourced snorkelling comparison for it, so I would not choose it for snorkelling alone.

Gear and staying safe

The sourced safety points are few. The rest is common sense and labelled as such.

• Sourced: the SPGA tells boat operators to watch for swimmers and snorkellers. SeyVillas says non-swimmers need a life jacket, and Anse Caiman is for experienced swimmers with a local guide. Enriching Pursuits calls Anse Lazio unsafe when waves are up.
• My advice, unsourced: wear a rash vest for sun on your back, do not touch or stand on coral, and do not snorkel alone at an exposed beach. Stay away from boat lanes at popular bays.
• Gear: a mask that fits your face matters more than anything else. I would bring my own mask and snorkel, and treat fins as optional for a calm bay. I found no sourced hire prices or shop locations, so I give none.

What are the marine-park rules and fees?

Non-residents over 12 need a valid ticket for the SPGA marine parks, and the SPGA publishes a short list of rules rather than a snorkelling code. Rules and fees, as the SPGA's visitor information page lists them:

• Fees for non-residents over 12: Curieuse Rs300, Ste. Anne Rs200, Ile Cocos Rs200, and Rs200 for Port Launay and Baie Ternay combined (one ticket covers both, says the SPGA's Port Launay page).
• Tickets can be bought online in advance, and the SPGA encourages it. At the parks you pay by card only, with "no cash payments". Cash is taken only at the SPGA main office.
• Keep the ticket and hand it to park rangers if they ask.
• Do not fish or collect shells, plants, corals or other aquatic life.
• Anchor or moor only in designated areas.
• Access is prohibited on Curieuse's northern coast, including Anse Badamier, and on Ste. Anne's nesting beaches.
• The SPGA's Ste. Anne page says the park is open seven days a week, 9 a.m. to 5 p.m. Its visitor page lists 8 a.m. to 5 p.m. daily for the marine parks, so check before an early start.

The pages I read do not say how to behave around turtles or whether you may feed fish, so do not touch, chase or feed anything. If you book a boat trip, ask whether the park fee is inside the price. I could not confirm whether visiting St Pierre needs its own ticket.

Is it right for beginners, children and non-swimmers?

Yes for all three, if you pick the spot. Choose sheltered, shallow bays and calm mornings.

• Beginners: SeyVillas lists Port Launay ("calm, flat waters") and Anse Royale as shallow and calm. It says Anse Royale is protected by the reef. It calls Fairyland Beach a good spot to watch fish and coral.
• Not for beginners: SeyVillas says Anse Caiman is for experienced swimmers with a local guide.
• Children: the SPGA lists marine-park fees only for non-residents over 12, so check the ticket rule for younger children when you book. Keep them within standing depth, with a life jacket.
• Non-swimmers: SeyVillas advises a life jacket, not a snorkelling vest, if you cannot swim. My advice: a guided boat trip beats going alone.

Seychelles or Maldives for snorkelling?

For snorkelling alone, the Maldives usually wins. Seychelles wins on scenery, beaches and choice of islands. Kuoni (updated March 2026) says many Maldivian islands have a house reef with marine life close to the shore. Even Koek, a Seychelles guide, says that for non-divers choosing on snorkelling alone, the Maldives wins, because its atoll lagoon structure puts far more interesting marine life within snorkelling range. In Seychelles you hunt for a good bay or take a boat (my reading).

Do not read "Maldives" as "pristine", though. The same global bleaching event hit the Indian Ocean. An Anantara sustainability manager and marine biologist reports sea temperatures past 31 °C and shallow nurseries (about 2 m) "glowing white" by June 2024. That is one operator's view, not a national figure.

I give no Maldives coral cover numbers because I did not find a source I could open. Choose Seychelles if the beach, the granite and the variety matter as much as the reef. Choose the Maldives if you want to snorkel every morning from your door. Whichever you pick, check whether your hotel has a house reef or a sheltered bay.

FAQ

Can you snorkel in Seychelles all year?

Yes. The water is warm all year, but visibility is "slightly reduced" outside the calm months, per SeyVillas, and some beaches get rougher. Choose a sheltered bay and go early.

Do I need a guide?

Not at easy, sheltered beaches. SeyVillas recommends a local guide for harder sites such as Anse Caiman, and a boat trip takes care of marine-park access.

Is snorkelling good near Praslin?

Yes, mainly at Anse Lazio on calm days, where the left side has better visibility according to one blogger. Praslin is also a handy base for boat trips to Curieuse and St Pierre.

Which island has the best snorkelling?

Praslin and Mahé, in my judgement. Praslin for Anse Lazio and Curieuse, Mahé for the number of bays and Port Launay. It is an opinion, not a ranking.

Is Seychelles better than the Maldives for snorkelling?

Usually not for reef snorkelling off the beach. Kuoni notes house reefs near the shore on many Maldivian islands. Seychelles is better for scenery and variety.

Can you see turtles and sharks?

Turtles, yes: Koek calls them the most reliably encountered large animals. Reef sharks are common but not a promise, and whale sharks are a seasonal boat-trip thing.

Is the coral dead?

No, but cover is low. The 2026 SeyCCAT report puts national live hard coral at about 14% and says the trend is declining. Fish, turtles and granite make up for much of it.
