A boat trip is one of the most popular day activities in Mauritius. Expect a full-day outing (usually 8am–4pm) that includes cruising along the coast, stops for swimming or snorkeling, and a barbecue lunch served on the boat or on a beach. The water is typically clear and warm, but the experience is social—boats carry 15–40 people. You’ll see turquoise lagoons, a few small islands, and sometimes dolphins. It’s relaxing if you like being on the water; it can feel long and crowded if you don’t.
The best time is April to early December, outside the main cyclone season. May–September usually offers the calmest seas and best visibility for snorkeling. Expect to pay around $60–$110 per person for a standard full-day catamaran or speedboat tour with lunch and drinks. Private charters or luxury options run $250+ per person. Book through your hotel or big platforms to keep flexibility for weather changes.
Pick a smaller catamaran tour to the northern islands if you want decent snorkeling and fewer crowds. Skip the big party-style speedboat trips to Ile aux Cerfs if you dislike loud music and lots of people. Bring reef-safe sunscreen, motion sickness remedies if you’re sensitive, and a waterproof bag for your phone.
