San Juan, Puerto Rico
Founded by the Danish in the 1600s, the busy cruise ship port of St. Thomas is the primary gateway to the U.S. Virgin Islands. The island’s main town of Charlotte Amalie is chock-full of 17th-century buildings, West Indian antiques, and cobblestone streets that offer a glimpse into what life was like during colonial times. As the most commercialized destination in the USVIs, it's also home to a slew of shopping and dining options. If it’s sun and sand you’re after (and really, why else would you be here?!), there’s no shortage of outdoor activities, including kayaking through mangrove lagoons, water sports galore, and miles of hiking trails that wind through the hilly landscape. St. Thomas has certainly proven itself as a prime tropical destination for those seeking a laid-back vibe with a bit of exotic adventure thrown in, and no matter how long you spend on this sun-drenched island, you’ll be sure to love every minute.
