Select participants and date
The speedboat punches through the Indian Ocean like a live wire—spray fanning the sun, the engine's chorus urging the island forward. You feel the boat climb each swell and drop, the shoreline of Mauritius shrinking into a strip of palm and reef as the guide points the bow toward Ile aux Cerfs. On a day like this the sea is a palette of blues: nearshore aquamarine over the coral beds, a deeper navy beyond the reef.

Adventure Tips
Use reef-safe sunscreen
Blue Bay is a protected marine park—choose reef-safe sunscreen and reapply sparingly to protect corals.
Bring a snug snorkel mask
Masks included, but if you have one that fits well you'll see more and waste less air; leak-free masks improve the experience.
Plan for motion
If you get seasick, take medication before boarding; morning departures are generally calmer than afternoon runs.
Carry a small waterproof bag
Keep phone, ID, and cash dry—there are short island stops but limited secure storage.
