Dolphin Watching, Tamarin Bay
Every morning, pods of spinner and bottlenose dolphins come to rest in Tamarin and Black River bays. The dawn boat trip, sometimes with a swim, is the west coast's signature experience.
Tip: Departs 6-7:30am from the Black River jetty (trips only allowed 6am-12pm); pick a respectful operator (distance, no encircling). Whales possible July-October.
What you'll see
Two species frequent the west coast: the spinner dolphin, known for its twisting leaps, and the bottlenose dolphin, bulkier and less acrobatic. After hunting offshore at night, they rest in the sheltered bays of Tamarin and Black River in the morning, and that rest is exactly what the rules are designed to protect.
What Mauritian law says
The activity is governed by the Tourism Authority (Dolphin and Whale Watching) Regulations 2012 (GN No. 154 of 2012, in force since 1 November 2012), enforced by the Mauritius Tourism Authority. Only a licensed operator, with a certified skipper, the Authority's label displayed on the boat and an approved propeller guard, may sell a trip. Swimming requires a separate licence.
Within 50 m of the nearest dolphin, no boat may enter; between 50 and 150 m, it must move at no-wake speed with no sudden changes of speed or direction. Boats approach from the side and run parallel: no approaching from behind or head-on, no circling, no driving through a pod. Feeding, touching or making noise to attract dolphins is banned.
For swimming: no more than 3 people in the water at once, lifeguard included; a lifeguard, first-aid kit and oxygen on board; the Alpha flag flying; a signed waiver and a briefing on calm, quiet swimming. Paid trips, whether watching or swimming, are only allowed from 6am to noon (amendment GN No. 228 of 2012). Kitesurfing, jet skiing and diving are banned within 500 m of the animals.
What about whales?
For whales, the no-go zone grows to 100 m and the regulated zone to 200 m. Swimming, diving or snorkelling with whales is prohibited, and in July 2024 the Tourism Authority reminded operators that allowing it is an offence. Be wary of any tour that promises otherwise.
Prices, times and getting there
Trips leave early, between 6 and 7:30am, from Tamarin or the Black River jetty, 45 minutes to an hour from Port Louis and 15 to 20 minutes from Flic en Flac. A shared 2 to 2.5-hour outing sells for roughly €45 to €65 per adult on booking sites; a full speedboat day with dolphins, Ile aux Bénitiers and a BBQ costs about Rs 2,400 per adult with a local operator (checked October 2026). Sightings are never guaranteed.
Choosing a responsible operator
Before boarding, look for the Tourism Authority label on the hull and ask whether swimming is covered by the licence. On the water, a good skipper throttles back well away from the pod, lets the dolphins come closer and puts swimmers in quietly, a few at a time. If several boats are racing towards the same pod, stay on board: you are responsible for your own behaviour. Bring a mask, snorkel, fins and seasickness tablets if needed.
Pair it with Ile aux Bénitiers and Crystal Rock, Whale Watching in the southern winter, Tamarin Bay or the Tamarin salt pans.
