Warm turquoise waters, perfect coral reefs and an extraordinary variety of marine life, Mauritius has all the ingredients for world-class snorkelling. Sitting in the heart of the Indian Ocean, this volcanic island is fringed by one of the largest lagoon systems in the world, protected by an almost unbroken barrier reef that shelters calm, crystal-clear waters from the open sea. Beneath the surface, you'll find a technicolour world of reef fish, sea turtles, rays, octopus and vibrant coral gardens. Whether you're a first-time snorkeller or a seasoned underwater explorer, Mauritius ranks among the best islands in the Indian Ocean for getting beneath the waves.
Can you snorkel in Mauritius?
Absolutely, and it's one of the island's most accessible and rewarding activities. The protected lagoons that surround much of Mauritius are naturally shallow and calm, making them ideal for snorkelling without the need for specialist equipment or experience. Visibility is generally excellent, particularly during the dry season from May to November, when rainfall is minimal and the water is at its clearest.
You don't need to be a confident swimmer to enjoy snorkelling in Mauritius either. Many of the best spots are just a short wade from the beach and snorkelling gear is widely available to hire at beach shacks and through hotels. For a more structured experience, guided snorkelling excursions are easy to arrange from most resort areas, and these are particularly worthwhile for reaching offshore sites or marine reserves where the underwater life is at its richest.
Snorkelling is a brilliant activity for all ages, making it a highlight of any Mauritius family holiday as well as a romantic addition to a more indulgent getaway.
Top 10 places for snorkelling in Mauritius
1. Blue Bay Marine Park
Blue Bay is widely considered the finest snorkelling site in Mauritius and it fully earns that reputation. Located on the south-east coast near Mahébourg, this protected marine park is home to over 50 species of coral and more than 70 species of fish. The water is shallow, calm and extraordinarily clear, perfect for spotting parrotfish, butterflyfish, moray eels and the occasional sea turtle drifting through the coral gardens.
2. Trou aux Biches
On the north-west coast, Trou aux Biches is one of Mauritius' most celebrated beach destinations and its snorkelling is every bit as impressive as the scenery above water. The lagoon here is calm and sheltered with healthy coral formations and a diverse array of reef fish. It's easily accessible from the beach and ideal for beginners and families.
3. Flic en Flac
Flic en Flac on the west coast boasts one of the longest stretches of white sand on the island and the snorkelling just offshore is consistently excellent. The reef here attracts a wide variety of marine life, including octopus, lionfish and trumpetfish, while the calm conditions make it comfortable to spend extended time in the water.
4. Île aux Cerfs
This stunning offshore island near Trou d'Eau Douce in the east is best known for its picture-perfect beaches, but the surrounding waters offer superb snorkelling too. Boat trips to Île aux Cerfs typically include stops at nearby snorkelling sites in the lagoon, where rays, reef sharks and shoals of vivid fish are regular sightings.
5. Pointe aux Piments
A quieter stretch of the north-west coast, Pointe aux Piments rewards those who venture slightly off the beaten path. The reef here is less visited than some other popular sites, which means more intact coral and more undisturbed marine life including sea turtles, which are frequently spotted in these waters.
6. Grand Baie
As the social hub of the north coast, Grand Baie is well-set up for water sports and snorkelling excursions. While the bay itself can be busy with boat traffic, organised trips out to nearby reefs and offshore islands offer excellent snorkelling in more sheltered conditions. It's also one of the best bases for dolphin-watching boat trips.
7. Mahébourg Lagoon
The broad, shallow lagoon around Mahébourg in the south-east is dotted with small isles and teeming with marine life. The area sits close to Blue Bay Marine Park and shares much of its biodiversity, meaning exceptional coral coverage and a dazzling variety of reef fish. It's also close to some of Mauritius' best beaches, making it easy to combine a beach day with a snorkelling session.
8. Coin de Mire (Gunner's Quoin)
For something more adventurous, a boat trip to Coin de Mire off the northern tip of Mauritius is well worth it. This protected nature reserve rises dramatically from the ocean and its surrounding waters are rich with marine life including large pelagic species not commonly seen closer to shore. Visibility here can be stunning on calm days.
9. Tamarin Bay
Tamarin on the west coast is best known as a surfing spot, but the calmer southern end of the bay offers rewarding snorkelling, particularly around the rocky outcrops where moray eels, sea urchins and a wide variety of reef fish make their home. Spinner dolphins are also regularly spotted in Tamarin Bay, making it a magical place to be in the water.
10. Rodrigues Island
For those willing to venture further afield, Rodrigues Island offers some of the most perfect snorkelling in the entire Indian Ocean. Its vast, shallow lagoon (proportionally one of the largest in the world) is almost entirely undeveloped with untouched coral, abundant sea life and a tranquillity that feels a world away from anywhere.
