Surrounded by the gorgeous Caribbean water on all sides, one of the more popular activities on the island is to get off it! Sailing, kayaking, windsurfing, snorkeling, diving and any other watersport you can imagine is easy enough to schedule, and many companies stand ready to take you out for the day. Since St. Martin is in the heart of the Lesser Antilles, it's also quite popular to visit other islands, such as Anguilla, St. Barts and Saba.

Day sails or specialty boat tours that offer everything from eco-snorkeling to party-in-the-sun itineraries are quite common. Daysailing companies that receive excellent reviews from past visitors include Soualiga Destinations Boat Tours and Captain Alan's Boat Charters.
