In winter, the visibility is poorer as the sea can get rough. Moreover, there are numerous sites to see, each having its own specificity. There are about 20 shipwrecks around the island where diving can be practised and beautiful pictures taken. Night diving is also organized all year round. For beginners, training is offered, usually with a limited number of divers.

The different sites are divided into 3 big diving zones, the North West from Tombeau Bay to the northern islets around Gunners Coin, the South West from Le Morne to Flic-en-Flac, and the East from Belle Mare to Mahebourg. The lagoon itself is not appropriate for scuba diving except Balaclava and Blue Bay Marine parks. The sites outside the coral reefs are suitable for diving and can easily be reached by boat.
