Guam Regional Transit Authority (GRTA) provides Guam with affordable, reliable, and accessible island-wide public transportation services.

The official GRTA App is an excellent way to keep informed about GRTA, notifications, and schedules. The bus schedule is a core feature of this app, making it a must have for regular riders or those who are thinking about riding the GRTA buses. The app also provides information about Paratransit reservations. Plus, it provides a neat Trip Planner.

When viewing the bus schedule, you may view it by village, by stops, by lines, or simply use the Trip Planner, by choosing the stop where you want to catch a bus and then choose your destination. Based on your choices, the app will give you the bus routes to make your trip successful.
