The southern part of the island, known as Sint Maarten, is the Dutch side. It is a constituent country within the Kingdom of the Netherlands. The northern part, Saint Martin, is a French overseas collectivity. In 2026, the Dutch side is famous for being the "livelier" half, hosting the major international airport (Princess Juliana/SXM), large casinos, duty-free shopping in Philipsburg, and the world-famous Maho Beach where planes fly low over sunbathers. While the French side is known for gourmet dining and a "European-village" feel, the Dutch side is the commercial hub. There is no hard border between the two, allowing 2026 tourists to drive freely between the "French flair" and "Dutch fun." A supportive tip: while the Euro is the official currency in French St. Martin, the Dutch side uses the Antillean Guilder but almost exclusively transactions in US Dollars in 2026.
