The sheltered bays of the west coast, from Tamarin to Black River and Le Morne, are where wild spinner and bottlenose dolphins come to rest in the early morning, and deeper water just offshore is home to sperm whales, with humpbacks passing through in the southern winter. Seeing them is one of the great experiences of Mauritius, but it needs to be done well, as the bays can fill with boats and the animals are easily stressed. This page links to Dolphins Encounter and Whale Watching with Dolswim, rated 4.6 from more than 180 reviews, a small operator praised by reviewers for keeping its distance from other boats and limiting how many people are in the water and for how long. The speedboat leaves the jetty at Grande Rivière Noire at seven in the morning with a skipper and a guide. You search the bays for dolphins and may slip into the water with snorkel gear to watch them pass beneath you, if conditions and the animals allow; swimming is optional. Then the boat heads out to sea, where a hydrophone lets you listen for whales and the crew watches for blows and fins. Breakfast, lunch, drinks and hotel transfers are included, and groups are capped at fourteen.
How it works: the trip lasts about four to five hours from a 7:00 departure at the jetty on La Jetée Road in Grande Rivière Noire. Hotel pickup and drop-off, breakfast, lunch, soft drinks, water, snorkel gear and live commentary are included. The price varies by date and group, and free cancellation is possible until 24 hours before. The jetty has no facilities, so come ready to board.
What you see: dolphins are seen on most mornings, though never guaranteed. Whale sightings are less certain: sperm whales live off the west coast for much of the year, and humpbacks pass in the southern winter, roughly from July to October. Swimming with whales is not permitted, so whale encounters are from the boat only.
Making the most of it: choose a responsible operator, follow the crew’s instructions in the water and never chase or touch the animals. The sea can be choppy, so take seasickness tablets if you need them. The tour is not suitable for pregnant travellers or anyone with back or heart problems, and children must be with an adult.
