Cruise up the coastline for a half-day of snorkeling and swimming in the calm, shallow waters. Lying just off the coast of Grand Case, the small island is the perfect place to spy coral reefs and their tropical inhabitants.

Set out from Simpson Bay, and travel through the lagoon up the St. Martin coastline, sightseeing along the way to Little Bay. When you arrive, ready your snorkeling gear as Captain Junior anchors the boat before you jump into the Caribbean waters. Float on the water's surface, peering into the underwater world of coral reefs and tropical fish.

After you finish snorkeling, climb back into the boat to enjoy a cold beer while snacking on a freshly made French baguette and Gouda cheese. Pick a spot in the sun to catch some rays on deck while the captain meanders down the shoreline back to the marina where you departed.
