Using GPS and navigation apps on St. Thomas can help you find your way, but there are some quirks and limitations to be aware of. Here is a guide to navigation for driving your Alamo, Enterprise, or National rental car on St. Thomas.
GPS Accuracy
GPS accuracy on St. Thomas is generally good on main roads but can be less reliable on secondary roads and in mountainous areas where satellite signals may be interrupted by terrain. Do not rely solely on GPS — use it as a supplement to your own awareness.
Google Maps and Apple Maps
Both Google Maps and Apple Maps work on St. Thomas and provide turn-by-turn directions. However, they may not always reflect the most current road conditions, closures, or one-way streets.
Download Offline Maps
Cell service on St. Thomas can be spotty, especially in mountainous areas and on the east end. Before your trip, download offline maps in Google Maps or Apple Maps so you can navigate without a data connection.
Local Road Names
Some roads on St. Thomas are known by local names that may not match what appears on GPS. For example, Route 30 is also known as the Veterans Drive or the main highway. Ask locals for directions if you are unsure.
Driving on the Left
GPS navigation apps are configured for the driving side of the road. On St. Thomas, make sure your app is set to give directions for left-side driving. Most apps detect this automatically, but verify before you start driving.
Tips for Using GPS on St. Thomas
- Download offline maps before your trip
- Use GPS as a supplement, not a replacement for awareness
- Pay attention to road signs, not just GPS directions
- Have a passenger navigate while you drive

Rental Car GPS
