Sint Maarten is small — you can drive around it in two hours — but its two best assets are hard to enjoy without help: the sea, and the fact that the interesting places are scattered over two countries. A good boat trip or a well-run island tour solves both.
Everything below is booked through GetYourGuide, which means live availability, free cancellation on most options and reserve-now-pay-later on many. Prices are indicative "from" starting points in US dollars and change with the season — tap any card for the current rate. Before you book, check three things on the listing: where the tour starts (the cruise port, a Simpson Bay marina and the French side are 20–45 minutes apart), the start time against your ship or your plans, and whether you need a passport — you do for anything that lands on Anguilla or St Barths.
Cruise passengers: independent operators here are used to ship schedules, but the responsibility for being back on time is yours. Choose tours that end at least two hours before all-aboard, and read our cruise-day guide first.
