Quick answer
The best snorkelling in Mauritius is at Blue Bay Marine Park in the south east, the reefs off Gabriel Island and the northern bird islands, and Trou aux Biches in the north. These spots have shallow, clear, protected water with healthy coral and easy entry, which makes them good for both first timers and experienced snorkellers.
The spots worth your time
Blue Bay Marine Park is the headline. It is a protected reserve in the south east with clear water and a lot of fish, best seen by boat over the deeper coral gardens rather than just off the beach. Gabriel Island and the northern islands give you reef snorkelling as part of a catamaran day. Trou aux Biches in the north is an easy beach entry with coral close to shore.
On the west coast, the dolphin trips often include a snorkel stop on the way back, so you can stack two things into one morning.
What you will see
Parrotfish, sergeant majors, the odd moray eel, sea cucumbers, and over the better coral, butterflyfish and angelfish. Visibility is usually strong in the protected bays, often 10 metres plus on a calm day. Morning, before the wind, is clearest.

Tips so you actually enjoy it
Bring or rent a proper mask that seals. Use reef safe sunblock or a rash vest instead of cream over the coral. Never stand on or touch the coral, it is alive and it is protected. And go early.
Coral and conservation, read this
The reefs are alive and protected, especially inside the marine parks like Blue Bay. Never stand on coral, never touch it, never take shells or anything else. Broken coral does not grow back in your lifetime. Use reef safe sunblock or a rash vest. Float, look, leave it as you found it.
What to bring and what to wear
Bring sunblock, a hat, sunglasses with a strap, a light jacket for the wind, and a towel. Wear your swimwear under your clothes so you are ready. A waterproof phone pouch is worth its weight for photos.
Use a rash vest or reef safe sunblock instead of thick cream over the reef, because normal sunblock damages coral and the better spots are protected. Take something for seasickness before you board if you are prone to it, not after, because once it starts it is too late.
How to book and avoid getting ripped off
Book direct with a licensed operator. That is the whole trick. Your hotel concierge can add 30 to 50 percent on the exact same trip, because they take a commission you never see. Cut them out and you keep that money.
Check three things before you pay. One, a real licence number you can see on the site, like TEL licence 17429. Two, clear pricing in rand, not a vague from price that grows at the jetty. Three, a real person on WhatsApp who answers. An operator with only a Gmail address and no licence is a gamble with your holiday and your safety.
Pay a deposit to hold your date, especially in the June to July peak when boats fill up fast. Confirm the day before for weather. A good operator will move you, not cancel you, if the sea turns.
