When people talk about snorkeling in Mauritius, they often think of Blue Bay or the northern spots. However, the southeast lagoon, around Mahébourg, is probably the best-preserved area on the island. Less touristy, calmer, with diverse marine life and still healthy corals, it's the ideal place for those who truly want to see something underwater.
Why the Southeast?
The coral barrier protects a turquoise lagoon of great clarity, especially in the middle of the day. Currents are gentle, making snorkeling accessible even for beginners. The southeast is also less exposed to mass tourism — there are fewer boats and the spots remain vibrant.
Three types of spots found in the Southeast
Coral gardens near the reef, where you can observe parrotfish, damselfish, trumpetfish, and sometimes green turtles.
Natural 'aquariums' near small islands, shallow areas where light plays on schools of colorful fish. Ideal for children and beginners.
The reef passes, deeper, for experienced snorkelers who want to encounter stingrays, barracudas, or Napoleon wrasse.
Choosing spots based on the tide
The best spot is never the same depending on the time and tide. At high tide, some corals that are too shallow at low tide become accessible; at low tide, other areas reveal their richness. This is why a private trip with a local skipper makes all the difference: they know three to four spots and choose the right one at the right time.
Practical Tips
Use reef-safe sunscreen (without oxybenzone or octinoxate). Do not touch corals or animals. Keep your distance from turtles: they tolerate human presence but don't like being approached too closely. If you're not comfortable with a mask, ask for a float vest — it's free on board.
