Off Malendure beach in Bouillante, on the leeward west coast of Basse-Terre, the Cousteau Reserve is a protected marine area that Jacques Cousteau himself praised, making it Guadeloupe's signature snorkeling and diving site. Around the two Pigeon Islands, the 'Coral Garden' (Jardin de Corail) massifs sit in just a few meters of water, crowded with staghorn and elkhorn corals, gorgonians and colorful parrotfish, angelfish and butterflyfish, while green and hawksbill turtles graze the seagrass beds right off the beach. Shallow zones of 2-3 m suit beginners, and in the dry season (December-May) visibility opens to 10-20 m. A bronze bust of Commander Cousteau rests on the sand at about 12 m, a famous landmark usually reached by divers and freedivers rather than surface snorkelers. As of 2026 it remains a core protected zone of the Guadeloupe National Park.

Good to know
SafetyThis is a very busy channel for dive boats, tour boats and jet skis. Always tow a surface buoy or float, stay close to the islets, and never swim across the boat lanes.
SafetyIt is about 1.5 km of open water from Malendure beach to the islets, with current in the channel between the two islands. Do not swim across; use a kayak or boat, and never snorkel alone-always go with a buddy.
SafetyFire coral and sea urchins live on the reef and rocks and cause burns or puncture wounds on contact. Never touch or stand on them; wear a rashguard/gloves. Beginners should defog the mask and acclimatize in the shallows first to avoid panic.
RulesThis is a core protected zone of the national park: do not touch or stand on coral or wildlife and take nothing. Use reef-safe sunscreen and moor only at designated buoys.
MannersKeep several meters from turtles-do not chase, touch or feed them-and never stand on the coral. Respect the animals and their habitat.
SeasonThe dry season (Dec-May) offers the best visibility and calmest water; the sea stays a warm 26-29°C year-round. The leeward coast is relatively spared from sargassum, but a heavy 2026 season is forecast, so check beach conditions before you go (June-November is the rainy and hurricane season).
CautionAvoid unlicensed operators and book with a national-park-approved dive or snorkel club. Prices, departure times and whether gear is included vary by season, so confirm the latest details before booking.
Practical info
The launch point is Malendure beach, known for its black volcanic sand, from which you cross roughly 1.5 km to the islets by kayak, glass-bottom boat or a guided snorkel tour (gear included, about 1.5-2 hours); self-guided snorkeling is possible via kayak rental. The best window is the dry season (Dec-May). Always confirm current prices, schedules, tour requirements and same-day sargassum/weather before heading out.
