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.
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.
Overall, Blue Bay is the 1st most popular snorkel dive spot of all 7 snorkeling dives in Mauritius.
