Trou aux Biches is widely regarded as one of the most beautiful and accessible beaches in Mauritius, and it's easy to see why. Nestled along the island's North Coast, this iconic bay boasts a gently shelving lagoon protected by a natural coral reef, creating conditions that are safe, calm, and wonderfully inviting. The name — loosely translated as 'Hole of the Does' — hints at the gentle, peaceful character of this place. It draws everyone from honeymooning couples to grandparents paddling with grandchildren, and it remains one of the top recommendations for first-time visitors to the island.
The beach itself stretches for several kilometres, lined with the shade of casuarina trees that rustle in the warm trade winds. Facilities are good, with sunbeds, beach vendors, and restaurants dotted along the shore, making it easy to spend a full, relaxed day here without needing to bring much at all.
Arriving at Trou aux Biches, you'll immediately notice the remarkable clarity of the water. The lagoon is shallow and protected, so the surface stays calm even when there's a breeze — ideal for young children and anyone who prefers a gentle introduction to the sea. The sandy bottom gives way to patches of coral reef just a short swim from shore, making it one of the most accessible snorkeling spots on the island.
You don't need to venture far to find something wonderful beneath the surface. Within minutes of putting on a mask and snorkel, most visitors are already marvelling at the underwater world below them. The entry points along the beach are easy to navigate barefoot, and the gradual depth makes it comfortable for swimmers of all abilities. Local vendors rent out snorkeling equipment at very reasonable prices right on the beach, so there's no need to bring your own if you're travelling light.
Snorkeling at Trou aux Biches is a genuinely magical experience, even for those who have never done it before. The reef community here is rich and diverse, and it's common to spot a wide variety of tropical fish darting between coral heads just below the surface. Look out for the vivid flashes of parrotfish, their bright blues and greens almost unreal against the sandy lagoon floor. Sergeant major fish — boldly striped in black and yellow — are often seen in small schools near the coral edges, and you may well encounter curious wrasse or the occasional graceful moorish idol gliding past.
Families with children are often delighted by the sea urchins and starfish visible in the shallower patches, and patient observers sometimes spot small reef octopuses tucked into crevices. The coral formations themselves are worth exploring slowly — branching staghorn corals, brain corals, and table corals create a miniature underwater city that rewards anyone willing to simply float and watch.
Trou aux Biches is a year-round destination, but the best conditions for snorkeling typically fall between May and December, when the southeast trade winds keep the air pleasantly cool and the sea visibility is at its finest. October and November offer particularly calm seas and excellent clarity in the lagoon. January through March is the warmer, wetter cyclone season — the water is bath-warm and the beach is still beautiful, but occasional swells can briefly reduce visibility. Even during this period, the protected nature of the lagoon means conditions are rarely unsuitable for a swim.
Early mornings are a wonderful time to snorkel — the light is soft, the beach is quieter, and the fish seem especially active before the main crowd arrives.
Trou aux Biches is located approximately 18 kilometres north of Port Louis, Mauritius' capital, and around 25 kilometres from Sir Seewoosagur Ramgoolam International Airport. By taxi or rental car, the drive from Port Louis takes around 25 to 30 minutes via the M2 motorway. Buses run regularly from Port Louis to Trou aux Biches village, making it an affordable and straightforward journey for independent travellers. Several hotels and resorts line the beach, and many visitors choose to base themselves here for the duration of their stay.
