Swimming with wild dolphins on the west coast of Mauritius is an unforgettable experience — provided it's done with respect for the animals. The dolphins of Tamarin and Black River Bay are wild animals, free to come and go. A good trip is not one where you 'force' an encounter; it's one where the boat knows how to position itself so that the dolphins come naturally.
Where do you see dolphins?
Spinner dolphins and bottlenose dolphins come to rest each morning in Tamarin Bay and around Black River after a night of hunting offshore. Opportunities to observe them are best between 7 AM and 10 AM, when the water is still calm.
Rules to follow
Do not approach closer than 50m by boat. Cut the engine when stopping. Never swim in the middle of a group: move to the side and let the dolphins come to you. Limit presence time to 15-20 minutes per group to avoid disturbing their rest. A reputable operator adheres to the code of conduct issued by local authorities.
Private or Group?
Large group dolphin tours (sometimes 20 to 30 boats concentrated in the same area) are stressful for the animals and frustrating for visitors. A private boat trip, maximum 6 people, with a skipper who knows the habits of the pods, allows for a gentler approach. Time in the water is also better managed: you wait until the dolphins are in a social and curious mood before getting in the water.
What to bring
Swimsuit, fins (provided), mask and snorkel, reef-safe sunscreen. No need to be an expert swimmer: a life vest is available. The trip lasts about half a day, departing early in the morning.
