Sides of Shell and Sea: Snorkeling with Turtles off Martinique’s Anses-d'Arlet
A calm half-day trip from Les Anses-d'Arlet to snorkel with green and hawksbill turtles and swim by Diamond Rock.
The motor tugs and sighs, and the bow of Captain Greg’s modern traditional boat parts the Caribbean like a slow hand opening a book. Light scatters across the water in pages—pale turquoise close to shore, deep indigo where the reef shelves fall away—and the little bays of Les Anses-d'Arlet appear as chapters, each one a shallow pocket of reef and sand that seems to have been placed there for a private reading. It takes less than an hour from the village harbor to reach the coves where green and hawksbill turtles graze among seagrass and coral, and in that short time the island’s geology, colonial past, and Creole present unfurl with the same plainspoken clarity as the captain’s directions: when you see a turtle, don’t touch; breathe slow; give space.
Trail Wisdom
Use Reef-Safe Sunscreen
Apply a mineral-based, reef-safe sunscreen at least 20 minutes before entering the water to protect coral and marine life.
Bring Your Own Mask
If you have a well-fitting snorkel mask, bring it—rental gear is often fine but a good fit prevents leaks and fog.
Go Early
Morning departures usually mean calmer seas, better visibility, and fewer boats at the snorkeling spots.
Respect Marine Life
Do not touch or chase turtles or corals—observe from a distance and float calmly to avoid disturbing them.

Rocher du Diamant (Diamond Rock) was once fortified by the British in the early 19th century and played a strategic role in naval conflicts; the coast’s coral terraces record Martinique’s volcanic uplift history.
