Guam
Getting around Guam: trains, buses, driving and domestic flights
There is no train on Guam. Rent a car (US$50–90 a day, 2026 estimate) if you want the south, the north cliffs or any beach outside Tumon; otherwise stay in Tumon and use the trolley (about US$4–5 a ride, day passes US$12–25, check) plus taxis for the airport. Public GRTA buses are rarely worth it for visitors.

Step by step: choosing and using each mode
Decide first whether you will leave Tumon. If your trip is a resort stay with beach days, the trolley plus taxis covers you and a car is optional. If you want Two Lovers Point at sunset, the southern villages, Talofofo Falls or the northern cliffs, book a car for those days.
- Book the car before arrival in peak season; airport counters can sell out.
- Check the under-25 surcharge and whether insurance is included before you sign.
- At trailheads and viewpoints, take valuables with you; break-ins are the known trap.
- For the trolley, buy a day pass if you will make three or more rides; keep the receipt.
- For GRTA, check the route and Sunday service before you rely on it.
- For taxis, ask your hotel to call one; few cruise the streets.
- For island flights, book refundable fares where you can — schedules change.
| If you want | Use | Watch |
|---|---|---|
| South island villages and Umatac | Hire car or guided south tour | Long drive; combine stops in one day |
| Tumon malls, dinner, Chamorro Village | Trolley or taxi | Trolley stops early; Wednesday night market is the busiest run |
| Airport transfer | Taxi or hotel shuttle | US$20–30 to Tumon (2026 estimate) |
| Saipan, Palau or Yap | Flight from GUM | Island-hopper schedules change |
Times are road estimates and vary with traffic.
Notes and traps
Guam is US territory, so road rules, signage and plugs follow US practice. Fuel stations are concentrated around Tumon, Hagåtña and Dededo; fill up before heading south. After typhoons, expect road debris, boil-water notices and short closures at some sites — check before you drive.
- No Uber or Grab; check for local ride apps before you land.
- Some south-island sites have short hours or close on Mondays (check).
- Government offices close on US federal and Guam holidays.
- Beach parks have basic toilets; malls and hotels are the clean fallback.
- Tipping: 10–15% for taxis, 15–20% in restaurants unless a service charge is added.
