St. Maarten (and the French side, Saint Martin) offers several incredible spots for turtle encounters in 2026, with the most reliable being Tintamarre Island. Located within the French Nature Reserve, this uninhabited island is a haven for green sea turtles that graze on the abundant seagrass beds just off the beach; you can reach it via a short boat excursion from Cul-de-Sac. Another top-tier location is Pinel Island, where the shallow, calm waters make it easy for snorkelers of all levels to spot turtles. On the Dutch side, Divi Little Bay is a frequent haunt for hawksbill and green turtles, often found swimming near the rocky outcroppings. If you are lucky, you might even see them at Mullet Bay or while snorkeling around the Underwater Sculpture Park. For the best 2026 experience, hire a local catamaran charter that specializes in "eco-snorkeling," as they know the exact coves where these gentle creatures are most active.
