Board a short boat from Sosua and slip into warm Caribbean water to explore two vibrant reefs—Three Rocks and a bay reef—then spend the afternoon on Sosua Beach. This half-day tour pairs easy snorkeling with a relaxed beach finish for travelers of all levels.

The boat slips away from Sosua's breakwater with a low, familiar hum. Salt air fills the small cabin and the Atlantic stretches flat and blue; the reef line—three dark shadows under the surface—appears like a promise. At the first stop, Three Rocks, the water is warm and clear enough to read the reef like a map: brain coral plates, spur-and-groove ridges, and curly-tailed parrotfish that flick through the corals as if chasing sunlight. The guide hands you a mask, fits your fins, and the ocean seems to lean forward, inviting you in.
