A typical catamaran cruise in Mauritius is a full-day trip (9am–4:30pm) that takes you to one or two offshore islands, most often Île aux Cerfs on the east coast. Expect sailing time, a few swimming/snorkeling stops, a barbecue lunch with drinks included, and a lot of time lounging on the net or deck. The boats carry 15–40 people; it’s social but not a party boat unless you pick the wrong one. Water is usually calm on the protected side of the reef, though the trip back can get bouncy if the wind picks up. You’ll see turquoise water and white sand, but the snorkeling is average—don’t expect pristine reefs full of fish.
Best time is May to early December when the southeast trade winds are lighter and seas are calmer. Avoid January–March; that’s cyclone season and rougher water. Expect to pay around $70–$110 per person for a standard full-day trip with lunch and open bar. Private or smaller-group options push $150–$200.
Pick the east-coast departures to Île aux Cerfs if you want decent swimming and beach time. Skip the west-coast “sunset cruise with dolphins” versions—they’re crowded, the dolphins are hit-or-miss, and the experience feels rushed. Bring reef-safe sunscreen, motion-sickness tablets if you’re sensitive, and cash for the optional parasailing or glass-bottom boat add-ons that operators push once you’re onboard.
