The US Virgin Islands are an unincorporated US territory. US citizens travel to the USVI with the same freedom as traveling between US states. No passport is needed. A valid government-issued photo ID (driver's license or state ID) is sufficient for travel between the US mainland and the USVI. There are no immigration formalities for domestic travelers at Cyril E. King Airport (STT) on St Thomas or Henry E. Rohlsen Airport (STX) on St Croix.
The USVI comprises three main islands: St Thomas, St John, and St Croix. St Thomas has the capital Charlotte Amalie, a major cruise port, and duty-free shopping. St John is two-thirds Virgin Islands National Park, with Trunk Bay beach and hiking trails through tropical forest. St Croix, the largest island, has the Christiansted and Frederiksted historic districts (both formerly Danish colonial), Buck Island Reef National Monument, and a growing craft rum scene. Ferries from Red Hook, St Thomas reach Cruz Bay, St John in 20 minutes for $7.50 each way.
