Northern-islands catamaran trip

The classic day out

This is the island-classic excursion from Grand Baie: a day on the water heading north to the dramatic basalt islet of Coin de Mire, then on to Île Plate (Flat Island) and Gabriel Island, with snorkelling stops over the lagoon and a barbecue lunch on or near the sand. Seats on a shared trip start from around ₨2,500 (about £39) per person, usually with the snorkelling and lunch bundled in; private charters cost more. Trips run as full-day excursions, typically leaving mid-morning and back late afternoon, weather permitting — and they do get cancelled in rough seas, so build in a spare day if it matters.

It’s a relaxed, scenic day rather than a wildlife expedition. The water is the star: turquoise lagoon, snorkelling over reef fish, and a couple of hours ashore on Gabriel Island’s sand. Manage expectations and you’ll have a lovely time.

Choosing the right boat

This is where it pays to be choosy. Two rules: book a Ministry of Tourism-permitted operator, and before you cast off, count the life jackets — there should be enough for everyone aboard, children included. Don’t board a boat that looks overloaded or under-equipped, and check the latest GOV.UK travel advice for Mauritius before you go.

On the experience itself, a smaller speedboat usually beats the big party catamarans. The large catamarans are cheaper and more sociable, but they pack people in and can tip into booze-cruise territory, with everyone snorkelling the same patch at once. A smaller boat means fewer passengers, more flexibility at the stops and a calmer day. Read recent reviews of the specific operator rather than booking the first leaflet you’re handed, confirm what’s included, and you’ve got the best full day the north coast offers.
