It’s usually a good idea to rent a car in St. Thomas. You can probably skip the rental if your only plan is to go back and forth between your hotel and the beach—but if you’re looking to go hiking or explore attractions like Drake’s Seat or the 99 Steps, then *you’ll need a car to get around.
Renting a car in the US Virgin Islands is as easy as renting a car in the states. You’ll just need to visit one of the rental companies at the St. Thomas airport, choose a car, fill out a form, and show your driver’s license. You can usually secure a lower rate by reserving your car in advance.
