The best snorkelling beaches in Seychelles

Seychelles snorkelling is granite and reef rolled together, which is what makes it different from anywhere else. The signature boulders that make these beaches so photogenic also run out under the surface, and where they meet the recovering coral you get clear warm water full of parrotfish, sergeant majors, the odd turtle and rays gliding over the sand. The catch, and there is one, is that the very beaches that fill the postcards are often the weakest for a mask, while the quieter marine parks do the heavy lifting. Follow the protection, not the fame.

The other half of a good snorkel day here is the food, and Creole cooking rewards an appetite earned in the water. Come out salty and you are rarely far from a kitchen grilling the morning catch, simmering an octopus curry or laying out ladob and breadfruit, and on Mahe the evening bazaar at Beau Vallon turns the post swim hunger into a proper outing. The ranked coves below are chosen for clear water and real fish, and we are honest about where the reef has thinned, where the wind decides the day, and where to find the table afterwards.

Be honest about the reef. Seychelles took hard knocks from warm water bleaching in past decades, and while the coral is recovering it does so unevenly, so some beaches that once teemed are quieter now. The healthiest fish life sits inside the marine parks, Port Launay and Baie Ternay in the northwest, Sainte Anne off Victoria, Curieuse off Praslin, where protection has let the reef hold its own. Set your expectations to a recovering Indian Ocean reef, not a pristine one, and the marine parks will still give you turtles, rays and clouds of reef fish.

Be honest, too, about the famous beach. Anse Source d'Argent on La Digue is the most photographed shoreline on earth and worth seeing for the boulders and the light, but it is a poor snorkel, shallow and broken by sandbars with water that clouds easily and little to hold fish. Tourists arrive expecting the swim to match the picture and leave underwhelmed. Go for the photographs, then take your mask to a marine park or a granite cove. The wind is the last variable, with the southeast trades stirring exposed coasts from May to September, so snorkel sheltered bays in the calm of the morning, and remember conditions are typical and never guaranteed.

The food and culture move is to build the day around a Creole table. Time the snorkel for the morning calm and surface hungry, then point yourself at a kitchen. The northwest coast near Port Launay and Beau Vallon does grilled fish and curries well, and the Beau Vallon bazaar on its market evenings is the island's great street feast of fresh catch, ladob and rum. On La Digue and Praslin the rhythm is slower still, a cycle to a takeaway, a plate of octopus curry, a long afternoon. The fish under the water are the headline, but the fish on the plate is why a Seychelles beach day lingers.

Seychelles is not a day bed and bottle service kind of place, and that is part of its charm. The scene is hotel beach bars, simple Creole restaurants on the sand and the famous beach kitchens above Anse Lazio and Anse Source d'Argent, rather than glossy clubs. After a marine park snorkel the natural rhythm is a long lunch and a slow afternoon in the shade of a takamaka tree. Our directory keeps an honest note of where you can settle in with service and where the beach is simply free and yours, so you can plan the afternoon around the morning swim.
