Praslin & La Digue

The ground between Praslin and La Digue is submerged granite. Giant boulders stack into canyons and swim-throughs at Ave Maria in the channel and at Sister Bank and Booby Island further out, and Channel Rock, midway to La Digue, breaks the surface at low tide; most of the diving sits between 5 and 25 m. Boats leave from Cote d'Or on Praslin, five minutes to a shallow coral bay and about 35 minutes to the outer banks. Marianne is run as a drift with blacktip and whitetip reef sharks; hawksbill and green turtles and eagle rays are reported along the granite slopes.

About diving in Praslin & La Digue

Diving runs off day boats from Cote d'Or on Praslin's north coast, where Whitetip and Octopus Diver are based; Praslin counts more than 17 named sites at depths of roughly 8 to 20 m. The rides are short and the day is built around them: five minutes to Anse Petit Cour in its sheltered bay, five to ten to Coral Garden, twenty out to Booby Island, and about 35 minutes to Sister Bank when the sea allows. There is no shore diving on the roster; every dive begins at a mooring or a live drop.

The terrain is granite rather than reef. Giant boulders lie submerged in stacks with swim-throughs wide enough to pass, at Sister Bank, Booby Island and Ave Maria, while Channel Rock, midway to La Digue, is a submerged granite reef whose tallest boulder breaks the surface at low tide. Hard and soft coral cover the shallower ground at Coral Garden and Anse Petit Cour. Blacktip and whitetip reef sharks patrol Marianne, hawksbill turtles and eagle rays are reported along La Digue's granite slopes, and green turtles live along the outer edges of the coral reefs.

The record is uneven between the two islands. The catalogue of named sites runs from the Praslin side and the operators there; on La Digue the dive operation at La Passe is a floating PADI centre that cruises the archipelago by yacht rather than a shore-based day-boat business, and it has no site list of its own. Ile Cocos, a marine park since 1996, lies about 7 km north of La Digue. Red Point sits inside Curieuse Marine National Park, declared in 1979. The area suits newly qualified divers and anyone who likes structure, light and short boat rides; divers after a wall dropping into open water should look to the outer Seychelles atolls instead.

2011–2025 averages. Sea surface: NOAA Coral Reef Watch, measured at the surface, so deeper water can run colder. Daytime high and rain: NASA POWER.

The southeast monsoon runs from May to September; the water is windiest and the visibility thinnest in July and August, while March, April and November log the clearest water.

Best months: March, April, November

Dive types & marine life

Blacktip and whitetip reef sharks are the reliable sighting, thickest on the Marianne drift. Octopus are logged at Ave Maria, Coral Garden and Red Point, hawksbill turtles and eagle rays along La Digue's granite slopes, and green turtles on the outer reef edges. Whale sharks are named in general accounts of La Digue but turn up in no dive-site record here, so they are chance rather than a plan.

How to get to Praslin & La Digue

Praslin has its own domestic airport with short hops from Mahe, and the dive centres sit on Cote d'Or at Anse Volbert. La Digue has no airstrip: the Cat Cocos ferry runs from Victoria Pier on Mahe to La Passe Quay, and up to eight crossings a day link La Passe with Baie Sainte Anne on Praslin.
