Thomas, the most developed, is brimming with activities and world-class shopping. St. Croix, bigger but sleepier, is the place to go for diving, snorkeling, and beach life. Both extend a warm welcome and both have interesting culture away from the beach.

Choosing between St. Croix and St. Thomas depends on your preferred vacation pace. St. Thomas is the quintessential "busy" island, known as the gateway to the USVI. It is home to Charlotte Amalie, a major cruise port famous for world-class duty-free shopping and a high-energy nightlife scene. It is perfect for travelers who want easy access to Magens Bay and the ability to "island hop" to St. John via a short ferry ride. In contrast, St. Croix is the largest but least visited of the three main islands, offering a much more "local" and laid-back atmosphere. It is a haven for history buffs, featuring the charming Danish colonial towns of Christiansted and Frederiksted. St. Croix is also home to the Buck Island Reef National Monument, one of the best snorkeling spots in the Caribbean. If you want luxury resorts, bustling crowds, and shopping, pick St. Thomas; if you prefer secluded beaches, diverse diving, and a quiet, authentic Caribbean feel, St. Croix is the superior choice.
