St. Martin is unique because it is not a single country, but an island divided between two different European nations. The northern part, Saint-Martin, is an "Overseas Collectivity" of France. It is part of the European Union, uses the Euro as its official currency, and follows French law. The southern part, Sint Maarten, is a "Constituent Country" of the Kingdom of the Netherlands. While it is part of the Kingdom, it is not part of the EU and uses the Netherlands Antillean Guilder (though the U.S. Dollar is widely accepted). In 2026, the border between the two sides remains "open," meaning tourists can drive from the French side to the Dutch side without showing a passport, though the cultural differences are stark: the French side is known for gourmet dining and a relaxed vibe, while the Dutch side is famous for its casinos, nightlife, and cruise ship terminals. Collectively, they are often referred to as "The Friendly Island," managed by two distinct local governments.
