When traveling to the U.S. Virgin Islands, U.S. Citizens enjoy all the conveniences of domestic travel – including online check-in – making travel to St. Croix easier than ever. As a U.S. territory, travel to St. Croix does not require a passport for U.S. citizens arriving from Puerto Rico, the U.S. mainland, or St. Thomas and St. John. Please ensure you carry a valid picture I.D., such as a U.S. driver's license, as you will need this to get through security from your departing airport. Entry requirements for non-U.S. citizens are the same as entering the United States from any foreign destination. Upon departure, a passport is required.

English is the official language of St Croix. During the fall and winter, 12 p.m. on the east coast of the United States is 1 p.m. on the island. During U.S. Daylight Savings Time, it’s the same on the eastern seaboard as it is on the island.

St. Croix’s temperature remains constant year-round, averaging about 80°F (27°C) each day with water temperatures around 70°F (21°C). Trade winds provide constant cooling and there is a rainfall in the late summer and fall season.

There is no need to purchase bottled water in St. Croix, as the island's tap water is safe to drink.
