The first marine protected area in the Indian Ocean, Sainte Anne Marine National Park, was established in 1973 and spans roughly 3.887 square kilometres off the coast of Mahé, Seychelles. Statistic from the Seychelles Parks and Gardens Authority.
Sainte Anne Marine National Park protects a network of six granitic islands, coral reefs, seagrass meadows, and the marine life that calls them home — all within a 15-minute boat ride from Victoria.
This is the most convenient spot on Mahé for a half-day snorkel and island walk, but the midday crowds can be real. Book a morning departure and you’ll have the reef and the tortoises largely to yourselves.
This article covers what to expect at the park, how to pick a tour, and the practicalities that made the trip work for our family — Michael, Lily, and Ethan included.
| Spot | Best For | Standout Feature | Time Needed | Key Tip |
|---|---|---|---|---|
| Sainte Anne Marine National Park | Snorkeling, island walks, glass-bottom boat rides | First marine park in the Indian Ocean (1973), six islands, giant Aldabra tortoises on Moyenne | Half-day (4–6 hours) or full-day | Book a tour that departs by 8–9 a.m. to avoid the worst of the midday boat traffic |

Sainte Anne Marine National Park
The park sits just off Mahé’s east coast, directly across from Victoria and Eden Island. Most tours combine a few snorkel stops, a land visit to Moyenne Island, and a Creole barbecue lunch — a format that suits anyone who wants to see the marine life without spending all day on the water.
Most tours start at Marine Charter next to the Seychelles Yacht Club in Victoria, with hotel pickup available islandwide. The boat ride to the park takes roughly 15–20 minutes. Tour operators typically offer glass-bottom boats or catamarans.
The shallow reef around Cerf Island is the main snorkelling site. Depths of 10–12 metres reveal healthy coral patches, parrotfish, angelfish, and the occasional reef shark. Expect about 30–45 minutes in the water. For underwater footage, the DJI Osmo Action 6 Bundle is waterproof to 20 metres and the 8K video captures the reef in crisp detail.
Moyenne is only 9.9 hectares, but it packs in hiking trails, a small history museum, and a population of Aldabra giant tortoises that roam freely. Brendon Grimshaw bought the island in the 1960s, planted over 16,000 trees, and turned it into a sanctuary. BBC Travel covered his story in 2022. Spend at least 45 minutes here to walk the trails and see the tortoises.
Most full-day tours include a Creole-style lunch on the beach: grilled fish, rice, and tropical fruit. Vegetarian and vegan options are limited, so check with the operator beforehand. The meal is included in the tour price.
After lunch, some operators offer kayaks and paddleboards, or you can take a glass-bottom boat ride to see the reef without getting in. This is a good option for non-swimmers or young children.
If you’re short on time, prioritise the snorkel stop at Cerf and Moyenne Island — the other islands are similar in character and can be skipped without missing the park’s highlights.
Practical Tips for Visiting Sainte Anne Marine Park
Choosing the right tour format and timing makes a noticeable difference. Below is a comparison of the main options to help you decide.
| Option | Typical Cost (per adult) | Best For | Limitation |
|---|---|---|---|
| Standard Group Tour (4–6 hrs) | €95–€130 | Best value; includes meals, gear, multiple stops | Can be crowded midday; less flexibility on timing |
| Private Charter (half-day) | €400–€600 total | Families/groups of 4+; custom schedule | Expensive for solo travellers or couples |
| Snorkel-Focused Trip | €75–€90 | Time-constrained snorkellers | Often no land stop or lunch included |
Midday crowding: between 11 a.m. and 2 p.m. the park sees the most boat traffic. Aim for an 8–9 a.m. departure to have the reef and Moyenne Island nearly to yourself. Also note that the park is closed on Sundays.
Use reef-safe sunscreen — standard sunscreens can damage coral. Many tour operators remind guests about this, but it’s worth bringing your own. Also pack a waterproof camera; the Insta360 X5 offers 8K 360° video and a replaceable lens, so you can shoot underwater and reframe later.

Before You Go: Sainte Anne Marine Park Questions Answered
Is the park suitable for non-swimmers?
Yes. Glass-bottom boat tours let you see the reef and marine life without entering the water. Many operators also provide flotation vests for snorkelling, so even weak swimmers can join in.
What is the best time of year to visit?
April–May and October–November offer calm seas and peak underwater visibility. The southeast trade wind season (May–September) can bring choppier conditions, while the northwest monsoon (December–March) is rainier and more crowded.
Can we see giant tortoises?
Yes — on Moyenne Island. A population of Aldabra giant tortoises roams freely. The island also has hiking trails, a small museum, and a “pirate’s grave” that adds a bit of history to the walk.
Are there any restrictions I should know about?
Feeding marine life, collecting shells, and stepping on coral are prohibited and may result in fines. Most ethical tours enforce a “look but don’t touch” policy. Reef-safe sunscreen is strongly recommended.
Beyond the Park: A Wider Seychelles Adventure
Sainte Anne Marine National Park is a compact, accessible introduction to the marine life of the Seychelles — the kind of half-day trip that works for families, first-time snorkelers, or anyone who wants to see coral and turtles without a long boat ride. For us, it was the morning that convinced Lily and Ethan that snorkelling was worth the salty taste. If you’re planning a longer stay, our guide to island hopping through Seychelles inner islands includes Praslin, La Digue, and more marine parks to explore.
