What Is St Martin? One Island, Two Sides
How French Saint-Martin and Dutch Sint Maarten share 87 square kilometres, and what that means for your trip
One Caribbean island with two sides: French Saint-Martin in the north and Dutch Sint Maarten in the south, sharing an open border, a major airport and dozens of beaches.

St Martin is one island shared by two countries. The northern, larger part is Saint-Martin, a French overseas collectivity with the euro, French law and its capital at Marigot; the southern part is Sint Maarten, a constituent country of the Kingdom of the Netherlands with its own government, its capital at Philipsburg and the international airport, Princess Juliana. The border is open and unmarked apart from welcome signs, but currencies, regulations, emergency numbers and entry rules differ, and these guides name the side for every place they mention.
The collection covers where to stay on either side, how the two airports and the onward ferries work, seasons and closures, dining, beaches, family planning, the private Terres Basses area and the day trip to Pinel Island.
One island, two countries: how the French and Dutch sides differ and what that means for planning.
