Whale Watching Lagoon Tour

The whale watching tour departs from the port of Mamoudzou, 97600 Mayotte, and heads into the lagoon and the waters just beyond the reef to look for humpback whales. Mayotte is a French overseas department in the Indian Ocean, and its warm lagoon is a calving and resting area for humpback whales that migrate from colder southern waters. The season is short, running from July to October only, and outside these months sightings are unlikely. Tours last 3 to 5 hours in total, with 20 to 40 minutes of travel offshore to reach the areas where whales are most often found.

Tours are run by local operators, including Planète Bleue, which can be contacted on +262 639 693 693. Boats carry small groups, and guides explain whale behavior and ensure that the boat keeps a respectful distance. Visitors may see mothers with calves, breaching, tail slaps and pectoral fin waving. Dolphins, including spinner dolphins, and turtles are also sometimes seen during the same outing, and some operators include a swim or lagoon stop when whales are not found.

A typical outing begins with a morning check-in at the Mamoudzou port, since seas tend to be calmer before the afternoon breeze. The boat travels out through the reef passes, spends the central part of the tour tracking and observing whales, and returns to port around midday or early afternoon. The afternoon remains free for lunch in Mamoudzou and a visit to the waterfront or market.

The best time is between July and October, and the morning departure is generally preferable for sea conditions. Food is not usually served on board, so visitors should bring water, a snack and sun protection, and consider a light windproof layer for the crossing. After the tour, restaurants and snack stands around the Mamoudzou waterfront serve grilled fish, brochettes and local dishes. Booking ahead is wise, since the season is short and places on small boats fill quickly.
