This 34-square-mile island in the eastern Caribbean comprises two territories—a northern French side (Saint Martin) and a southern Dutch side (Sint Maarten). The French side is known for its long sandy beaches, upscale boutiques, outdoor markets and—naturellement—superb cuisine. The Dutch side offers a younger vibe and a greater number of lively resort beaches, a vibrant—and often rum-fueled—nightlife scene, and cruise-baiting duty-free emporiums selling jewelry and liquor. The island is so tiny you can enjoy two entirely different countries and cultures without breaking a sweat—the ultimate dual-destination vacation.
