Why Choose Mauritius for Snorkelling and Scuba Diving?

Mauritius is surrounded by a 150 km-long barrier reef, protecting its lagoons and providing calm, safe waters for snorkelling. For scuba divers, the island offers dramatic underwater topography, reefs, cliffs, pinnacles, and shipwrecks that attract a variety of marine species. With water temperatures averaging 23–28°C year-round and visibility of up to 30 meters, conditions are almost always ideal.

Best Spots for Snorkelling in Mauritius

Located in the southeast, Blue Bay Marine Park is famous for its protected coral gardens. Snorkellers can see over 40 species of coral and a variety of tropical fish like angelfish, damselfish, and parrotfish. Glass-bottom boat tours are also available for those who prefer to stay dry.

2. Trou aux Biches

On the northwest coast, Trou aux Biches offers shallow, calm waters perfect for beginners. It’s a great place to spot butterflyfish, trumpetfish, and sometimes turtles. The beach here is also ideal for relaxing after your snorkelling session.

Small but lively, Pereybere is another top snorkelling spot. Its proximity to coral reefs makes it easy to spot clownfish, starfish, and even small rays in the clear lagoon.
