In brief, a typical catamaran cruise in Mauritius can range from a few hours for half-day trips focusing on activities like snorkeling, to full-day excursions lasting around 7 to 8 hours with multiple stops for swimming, exploring islands, and enjoying onboard meals. Sunset cruises are shorter, usually around 2 to 3 hours, designed to offer stunning sunset views over the Indian Ocean. The specific duration depends on the tour package and activities included, so it’s best to confirm details with the cruise operator.
