A trip to the U.S. Virgin Islands is one of the most fulfilling Caribbean experiences a traveler can get. The three main islands, St. Croix, St. John and St. Thomas, offer a wide variety of activities, from historical sites to national parks, and attract two million visitors a year.

For U.S. citizens, visiting the U.S. Virgin Islands is easy. Because it’s a United States territory, U.S. citizens do not need a passport to enter. This makes the group of islands a popular cruise stop as well as a convenient location for destination weddings.

The U.S. Virgin Islands are diverse and each of the three main islands offers something different. St. Thomas attracts travelers looking for active beaches, bustling nightlife, excellent shopping and a historic downtown district. The island, which is also home to Charlotte Amalie, the territory’s capital, welcomes many travelers every year and also has the most popular cruise port in the Caribbean.

St. John is perfect for travelers looking for a vacation full of outdoor adventure. Much of the island (7,000 acres) makes up the Virgin Islands National Park, part of the U.S. National Park Service. The park has 20 hiking trails as well as many beaches, coral reefs and historic ruins ready for exploration. St. John also has many opportunities to relax in luxurious villas and vacation rentals, and many amazing beaches to visit.

St. Croix strikes a good balance between St. Thomas and St. John. It’s the largest of the main islands as is referred to as the “big island”. It offers plenty of opportunities for outdoor activities, like snorkeling and hiking in the rain forest, but also has a good amount of city-based activities, like visiting museums, historic sites or the horse track. Diving is also a popular activity on St. Croix, where you can see coral reefs, shipwrecks and a natural underwater wall all in one day.

Traveling between the three main islands couldn’t be easier – travelers can choose to island hop by ferry, plane or water taxi. This allows travelers to experience the entirety of the U.S. Virgin Islands, which is an unforgettable destination.
