Saint Barthélemy (or St. Barth if you’re short on time) is where the Caribbean goes when it wants to be a little more polished. Think powder-soft beaches, low-key luxury, and a surprisingly relaxed island rhythm once you step away from the superyachts in Gustavia. It’s small, French, and effortlessly photogenic, with quiet coves, excellent food, and that “how is the water this blue?” kind of coastline. Don't be surprised if you spot a celebrity or two!
