Réunion Island Safari Boat Cruise, Dolphin and Whale Watching

Saint-Gilles-les-Bains, the seaside heart of the west coast

Saint-Gilles-les-Bains is the best-known seaside town on Réunion Island, part of the commune of Saint-Paul on the dry, sunny west coast. Its small harbour, set below the church and next to the aquarium, is the starting point for most boat trips on the island, and the town has beaches, cafés and a relaxed tropical atmosphere. Behind it, green slopes climb steeply toward the high interior.

Boarding here makes this one of the easiest things to do in Réunion Island: there is parking near the port and the outing lasts only two hours, so it fits a morning before the beach or a drive into the mountains. Departures at 08:30 and 10:45 take advantage of the calmer morning sea, when the light is also ideal for photos.

The west coast of Réunion seen from the sea

Once out of the harbour, the boat follows the west coast at a gentle pace. From the water you see the line of the coral reef protecting the lagoons, the beaches of Boucan Canot and the Hermitage area, and above them the dramatic outline of the island, a volcanic peak that rises from deep ocean to more than 3,000 metres. Close to the shore the sea drops quickly to great depths, which is why large marine animals come so near.

Even on a day with few sightings, the trip is a beautiful way to see Réunion from a new angle. The crew stops for photos and explains the geography and the marine life along the way. A light snack is served, with tea, coffee, water and juice and pastries or samosas depending on the departure time.

The dolphins of Réunion Island

Dolphin watching in Réunion is possible all year. Spinner dolphins, famous for their spinning leaps, often travel in large groups along the west coast, while Indo-Pacific bottlenose dolphins are seen in smaller pods closer to the reef. Watching them ride the bow wave or surface around the boat is the moment most guests wait for, and children are usually delighted.

The boat follows local guidelines for approaching cetaceans: a slow, steady approach, a respectful distance and a limited time near each group, so the animals are never stressed or chased. Swimming with the animals is not part of this cruise. Your crew explains the behaviour of each species and how the waters around Réunion are protected.

Humpback whale season off Réunion

From about June to October, during the southern winter, humpback whales migrate from Antarctic waters to the warm sea around Réunion to mate and give birth. This is the best time for whale watching in Réunion Island: you may see blows on the horizon, mothers resting with their calves, tail flukes rising above the water and, on lucky days, a full breach.

Whales are wild animals and their numbers vary from year to year, so sightings are never guaranteed, even in season. Outside the whale months the cruise focuses on dolphins and the coast. If you are planning a trip specifically for whales, July to September is usually the peak, and early departures often offer the calmest sea.
