East of Madagascar and Reunion Island, the snorkeling in Mauritus offers calm blue water to explore. The best Mauritus snorkeling can be found at Blue Bay Marine Park located on the southeast coast and south of Mahebourg. While it can be access from shore, most snorkelers feel the best snorkeling can be reached only by boat. There is some good snorkeling at Blue Lagoon Beach on the east side point of Blue Bay, but you’ve really got to go to the far western end of Blue Bay Beach around the rocks to reach the Blue Bay Marine Park snorkeling. There you will find large table corals and fuchsia mushroom corals in clear water from 15 to 25 feet deep. While snorkeling Blue Bay, you may encounter sergeant majors, moorish idols, wrasse, clownfish, damselfish, and parrotfish. The area is popular with boaters, so exercise care when snorkeling here. Further offshore are two popular sections called Roche Zozo and Colorado.
A popular snorkeling spot is the Ile Aux Cerfs Lagoon located 1 mile southeast of Trou d Eau Douce on the east coast. This boat accessed snorkeling spot in the middle of the lagoon near the barrier reef tends to have older decaying coral but good marine life. While snorkeling in the lagoon, you may encounter parrotfish, butterflyfish, surgeonfish, damselfish, and giant clams.
On the northwest coast, there are two good snorkeling spots located near each other. The Point Aux Piments snorkel spot near the Recif Attitude Hotel has a protected reef about 600 feet offshore. The water depth is from 3 feet up to 30 feet deep and provides habitat for butterflyfish, chromis, damselfish, goatfish, pipefish, wrasse and surgeonfish. There are also a few hawksbill turtles around. A little further north, the more popular Trou Aux Biches is good for families but watch for boats the further you venture offshore. While snorkeling Trou Aux Biches, you may encounter starfish, damselfish, triggerfish and some dolphins.
Other snorkeling spots include Poste Lafayette on the northeast coast, Flic en Flac beach on the west coast and Le Morne beach on the southwest coast.
The best time of year for snorkeling off Mauritus is during the summer from December through March. The water water is ideal habitat for plentiful marine life and the marine plants bloom. But the water temperature is good all year round for snorkelers.
