St. Martin offers a variety of wildlife viewing opportunities across both its French and Dutch sides. For marine life, the St. Martin Nature Reserve in the northeast is the premier spot; you can see humpback whales and dolphins in the Man of War Shoal Marine Park or snorkel at Pinel Island to find sea turtles and vibrant reef fish. Birdwatchers should visit the "Important Bird Areas" such as the Great Salt Pond or Little Bay Pond to see pelicans, herons, and egrets. On land, the Emilio Wilson Estate and various hiking trails like the Froussards footpath are home to endemic reptiles and iguanas. For a more structured experience, Parrot Ville Bird Sanctuary on the Dutch side allows for up-close interactions with exotic tropical birds. In 2026, eco-tours and horseback rides through the mangroves remain popular ways to witness the island's biodiversity while supporting conservation efforts aimed at protecting the local seagrass beds and coral reefs.
