The legal drinking age on the Dutch side of St. Maarten (Sint Maarten) is 18 years old. This is the same as the French side (Saint Martin). In 2026, the island remains a popular destination for younger travelers due to this lower limit compared to the U.S. (21). However, local authorities and business owners have become stricter about checking IDs in recent years, particularly in the popular nightlife districts of Simpson Bay and Maho. While the law is 18, individual establishments have the right to set their own entry requirements (some clubs may require you to be 21 for entry). Additionally, even though the legal age is 18, public intoxication and driving under the influence are taken very seriously by the Korps Politie Sint Maarten, with heavy fines in place to ensure that the island's vibrant nightlife remains safe for both residents and international tourists.
