Snorkeling in Mauritius: What You Need to Know

Expect warm, clear water over shallow reefs teeming with colorful fish, occasional turtles, and the odd ray. Most trips last 4–6 hours and combine two or three snorkel stops with time on a boat. The experience is gentle and suitable for beginners; the water is usually calm inside the lagoon, though it can get choppy if you head to the outer reef. Visibility is typically very good (15–25 m) but drops after rain or on windy days.

The best time is October to April when the sea is warmest (26–29 °C) and winds are lighter. June to August is cooler, windier, and cheaper, but the water can be a bit rough and visibility more variable. Expect to pay around $65–110 per person for a half-day trip that includes gear, snacks or lunch, and transport from your hotel. Private or small-group catamaran options sit at the higher end; larger shared boats are cheaper but more crowded.

Pick a small-group tour that visits two reef sites rather than one that adds a long stop at Ile aux Cerfs for photos and crowds. Skip anything promising dolphin swims—wild dolphin encounters are unpredictable and the boats often chase pods, which isn’t great for the animals or your snorkeling time. Bring your own mask and snorkel if you have them; rental gear is usually average.
