The northern islands of Mauritius—Coin de Mire, Île Plate, Île Ronde, and Île aux Serpents—are uninhabited volcanic outcrops ringed by coral reefs and protected as marine reserves. Reaching them requires a boat excursion departing from Grand Baie, typically aboard a catamaran that combines island views, snorkeling stops, and lagoon navigation. This guide covers departure logistics, what each island offers, and the practical steps to book your trip.
Quick answer
A mauritius northern islands tour departs daily between 08:00 and 10:00 from Grand Baie Public Beach, with most excursions running seven days a week. The islands themselves are free to approach, but transport and guided activities are provided by licensed operators whose fees vary by itinerary, vessel type, and inclusions such as lunch or snorkeling gear. Early departure slots fill quickly during peak season, so advance booking is standard.
The northern archipelago sits five to twelve kilometers offshore, a cluster of seabird sanctuaries and submerged basalt ridges that form one of Mauritius's most biodiverse marine zones. Coin de Mire, the closest and most frequently visited, rises 162 meters from the ocean and hosts red-tailed tropicbirds and endemic geckos. Île Plate, the only island where landing is occasionally permitted under strict wildlife protocols, shelters fossilized coral terraces and the remnants of a nineteenth-century lighthouse. Île Ronde and Île aux Serpents remain off-limits to preserve their populations of Telfair's skinks and Bojer's skinks, species found nowhere else on earth. Most operators structure a mauritius northern islands tour as a half-day or full-day circuit. Half-day itineraries typically sail to Coin de Mire for a snorkeling pass along the reef's drop-off, where visibility averages fifteen to twenty-five meters and parrotfish, surgeonfish, and occasional hawksbill turtles are common. Full-day excursions extend the route to Île Plate or Îlot Gabriel, a shallow sandbank farther north that serves as a lunch anchorage. Catamarans are the dominant vessel—stable in the channel's cross-swell and equipped with shade nets, snorkel platforms, and onboard facilities—though smaller speedboats offer express routes for photography-focused groups. Departure logistics are tightly linked to tide and wind. The lagoon passage from Grand Baie to open water is navigable at all states of tide, but the return crossing is smoothest before midday trade winds build. Operators schedule launches between 08:00 and 10:00 to maximize calm conditions around the islands and ensure return by mid-afternoon. Weather cancellations are rare but do occur during cyclone season, December through March, when swells exceed safe thresholds. Confirmed bookings are typically contacted the evening before if conditions require rescheduling. Prepare for equatorial sun exposure—shade on deck is partial, and reef reflection intensifies UV. Reef-safe sunscreen is mandatory under marine-park regulations, and operators may refuse entry to passengers wearing chemical formulations. Snorkeling ability is not required; most boats provide flotation vests and briefings for first-timers. The seabed around Coin de Mire ranges from three to twelve meters, with shallower coral gardens accessible to all comfort levels. Waterproof phone cases and polarizing filters are recommended for capturing the gradient shift from turquoise lagoon to indigo channel. Contact the Grand Baie departure point directly at +2306312396 for real-time availability, or consult the Mauritian Wildlife Foundation's resource hub at mauritian-wildlife.org for conservation updates and seasonal wildlife activity. The northern islands remain one of the island's least-altered coastal ecosystems, and every excursion contributes to the monitoring data that informs their protection.
