Snorkeling in Guadeloupe: the best mask-and-snorkel spots

Guadeloupe offers some of the best snorkeling spots in the Lesser Antilles, with water at 27-28 °C all year round. The Pigeon Islets (Cousteau reserve), Petite-Terre and the Porte d’Enfer are the three must-sees. Green turtles can be encountered freely at Malendure. From a catamaran at anchor, every spot feels different: you slip straight into the water from the boat, with no schedule to follow, in time with the tide.

Why is Guadeloupe an exceptional snorkeling destination?

Guadeloupe is home to the largest coral barrier in the Lesser Antilles and to protected marine nature reserves, which makes it an ideal playground for snorkeling, or mask-and-snorkel diving. The water stays at 27-28 °C all year round: no thick wetsuit needed, a UV-protection rashguard is enough for a comfortable outing.

The archipelago offers two main types of spots: free-access beaches (Malendure, Petit-Havre, Porte d’Enfer) and reserves reachable only by organized excursion (Pigeon Islets, Petite-Terre). The wildlife is among the richest in the French Caribbean - green turtles (Chelonia mydas) and hawksbill turtles, lemon sharks, spotted eagle rays, barracudas, parrotfish, butterflyfish and surgeonfish populate the reefs depending on the area. The distinction between the two turtle species matters: the green turtle frequents the seagrass beds of Malendure, while the hawksbill turtle is found mainly at the Pigeon Islets and at Petite-Terre.

The Pigeon Islets and the Cousteau reserve: Basse-Terre’s legendary spot

The Pigeon Islets, less than a kilometer from Malendure beach, are home to three snorkeling zones listed within the Cousteau reserve - the Coral Garden, the Aquarium and the Pool. It is the best-known spot in the archipelago, and rightly so.

Access is only by boat from the Malendure jetty (Bouillante), a 5 to 10 minute crossing. The three sub-spots have distinct profiles. The Coral Garden offers stands of elkhorn coral (acropora palmata), schools of barracudas and hawksbill turtles. The Aquarium concentrates an exceptional density of multicolored corals and reef fish - jacks, trunkfish, blue surgeonfish. The Pool is the most accessible zone, shallow, current-free, ideal for children and beginners.

Expect to pay from 45 € for a half-day guided snorkeling outing from Bouillante (indicative price, to be confirmed with local operators). To explore the Pigeon Islets at your own pace, free of any group-boat schedule, our catamaran cruises from Bas-du-Fort make these sites natural anchorage stops - you enter the water straight from the boat and come out whenever you like.

Petite-Terre: where to swim with turtles and lemon sharks in a protected reserve

Petite-Terre is a national nature reserve accessible only by organized excursion, where you can swim with harmless lemon sharks, dozens of turtles and spotted eagle rays in a shallow lagoon. It is probably the most spectacular spot in the archipelago for wildlife observation.

The reserve has been protected since 1998. Independent navigation is forbidden there, and a quota of a maximum 200 visitors per day is enforced to preserve the ecosystem. The excursion departs from Saint-François, a 40 to 50 minute crossing on a fast boat. Expect to pay between 120 and 170 € all-inclusive depending on the operator and the package chosen (catamaran with a Creole meal or a half-day fast boat).

The wildlife is exceptional: lemon sharks of 1 to 1.50 m (perfectly harmless), green and hawksbill turtles, spotted eagle rays, stingrays, barracudas. The dorsal fins of the lemon sharks are often visible from the boat even before you put on your mask. On the beach, the Lesser Antillean iguana - an endemic species - is present in large numbers. The rules are strict: a minimum distance of 5 m from the turtles, no touching the corals, the shells or the sand. Some catamaran cruises from Bas-du-Fort call in at Petite-Terre - an anchorage you cannot reach any other way, one that few holidaymakers get the chance to see outside a group of 30 people.

The Porte d’Enfer at Anse-Bertrand: Grande-Terre’s little-known sanctuary

The Porte d’Enfer is a natural lagoon tucked between limestone cliffs, with calm water sheltered from the Atlantic currents - one of the few spots on Grande-Terre suited to beginners and families. Its imposing name (which means “Hell’s Gate”) contrasts with a gentle, unspoiled snorkeling experience.

The site is in the commune of Anse-Bertrand, in the north of Grande-Terre. Access is via a coastal path from the Porte d’Enfer car park - bring sturdy shoes and go early in the morning, when the sea is at its calmest. You will come across parrotfish, sea fans, barracudas, sea urchins, starfish and, occasionally, turtles. The water sheltered from the trade winds is the site’s strong point: in strong wind, when other spots are swept by the waves, the sheltered part of the Porte d’Enfer stays usable. Take care, however, not to cross the reef beyond the lagoon in bad weather.

La Perle beach at Deshaies: the postcard spot of the north coast

La Perle beach, in the commune of Deshaies, offers snorkeling with free access from the beach at its rocky ends, with schools of tropical fish and corals in shallow water. It is one of the most photographed spots in Basse-Terre.

Access is free, with a car park and restaurants on site. The areas richest in wildlife are the northern and southern ends of the beach, where the rocks take over from the sand - starfish, sea urchins, parrotfish and schools of colorful tropical fish are plentiful there. Choose a calm-sea day: too strong a swell makes the area difficult and harder to read underwater. Combine it with Petite Anse, less than 100 m away: a small wild beach framed by rocks, reachable by path, with no facilities at all, where green turtles are frequently observed.

Petit-Havre at Le Gosier: the coral barrier within fin’s reach

Petit-Havre is one of the few beaches on Grande-Terre to offer a coral reef accessible directly from the sand, between Le Gosier and Sainte-Anne. The major asset: zero excursion, zero ticket, a mask and fins are all you need.

To get there, take the RN4 toward Sainte-Anne, then the “Plage de Petit-Havre” sign at Mare-Gaillard. The gentle slope at the water’s edge is ideal for children. Parking is limited (narrow road), so it is better to go on a weekday. Blue surgeonfish, snappers, corals and green iguanas occasionally seen in the depths bring the coral barrier to life. Watch out on swell days: surfers use the same spot, and underwater visibility drops.

Marie-Galante: snorkeling at the end of the world, far from the crowds

Marie-Galante offers snorkeling less spectacular than the flagship spots of Basse-Terre, but a preserved atmosphere and calm waters - ideal for anyone seeking authenticity far from the tourist circuits. The island is worth it above all because it does not feel like a conventional seaside destination.

The island is reachable by ferry from Pointe-à-Pitre or Saint-François, between 45 and 75 minutes of crossing. The spots to explore are Anse Feuillard and Capesterre beach, with accessible seabeds, less dense in corals than Basse-Terre but rich in reef fish, conchs (the local giant whelks) and seagrass beds. Marie-Galante is a natural stop on a sailing cruise from Bas-du-Fort - an overnight anchorage off Capesterre turns the discovery of the island into something that hurried tourists never see.

Where to swim with turtles in Guadeloupe: the most reliable spots

The three most reliable spots to swim with turtles in Guadeloupe are Malendure beach (turtle bay, free access), Petite-Terre (protected reserve, excursion required) and Petite Anse at Trois-Rivières. Each spot has a different profile depending on your level of experience and the type of visit you want.

At Malendure, nicknamed “turtle bay”, the seagrass beds on the Petit Malendure side (north) attract green turtles that can be observed from the beach with no logistics at all. It is the easiest spot to access. Petite-Terre offers the highest probability of observation - green and hawksbill turtles share the lagoon with lemon sharks - but the guided excursion is mandatory. Petite Anse at Trois-Rivières, calm and little-visited, is a third option for anyone wanting to avoid organized outings. In all three cases, the observation rules are the same: a minimum distance of 5 m, never touch or follow a turtle, do not surround it, do not use an underwater flash. The turtle must be able to come up to breathe freely.

The Pigeon Islets are among the iconic anchorages of our catamaran cruises to the Pigeon Islets - a chance to observe hawksbill turtles and barracudas straight from the boat even before putting on your mask.

When is the best time to go snorkeling in Guadeloupe?

The best time for snorkeling in Guadeloupe is from December to April, during the dry season (the “carême”), when the sea is at its calmest and visibility is optimal. Snorkeling is technically possible all year round, but the cyclone season (June to November) can interrupt outings for several days in a row.

The Guadeloupean dry season runs from January to April: regular but moderate wind, calm sea, clear sky. The water stays at 27-28 °C all year round, with no noticeable variation between summer and winter - a rashguard or a light wetsuit is enough. The wet season (the off-season, from June to November) brings more frequent rain, a rougher sea and hurricane risks. The months from December to April also correspond to Sailoe’s Caribbean charter season, with regular departures from Bas-du-Fort: the ideal period to combine a sailing cruise with snorkeling at the best spots. To head out in the best conditions, choose the morning - the sea is calmer and the light is optimal for seeing the colors underwater.
