A typical catamaran trip in Mauritius is a full-day cruise (usually 9am–4:30pm) that takes you to one or two offshore islands, most often Île aux Cerfs on the east coast. Expect turquoise water, snorkeling stops over shallow reefs, a barbecue lunch served on board or on the beach, and plenty of time to swim or lounge on the deck. The boat carries 15–40 people; it’s social but not a party boat unless you specifically choose the ones with loud music and unlimited rum. The motion is gentle in normal conditions, though it can get choppy if the wind picks up.
The best time is May to October when the southeast trade winds are steadier and the sea is calmer on the east and north coasts. December–March brings warmer water but higher chance of rain and rougher swells. Expect to pay around $70–$130 per person depending on whether it’s a basic tour with lunch or one that includes drinks, better snorkel gear, and a smaller group. Cheaper options often mean bigger crowds and less time in the water.
Pick the east-coast route to Île aux Cerfs if you want a proper beach stop; skip the west-coast versions unless you’re staying on that side—they tend to be more crowded and the snorkeling is usually weaker. Bring reef-safe sunscreen, a waterproof bag for your phone, and motion-sickness remedies if you’re even slightly prone. Book a morning departure so you’re not stuck in the afternoon heat with no shade left on the boat.
