Top-rated rental companies and the best ways to get around the island
A rental car is the single best investment you can make on a Guam trip. The island has no train system, buses run infrequently on limited routes, and taxis/rideshares quickly become expensive for multiple excursions. With a car, you can explore the north coast's pristine beaches, the south's dramatic cliffs and waterfalls, historical WWII sites, local village restaurants, and scenic coastal drives — all on your own schedule. Most rental companies are concentrated near the airport and Tumon hotel strip.

Car rental companies in Guam operate from two main locations: Antonio B. Won Pat International Airport and pickup points in Tumon near the major hotels. Airport pickup is convenient on arrival but often marginally more expensive due to airport access fees. Hotel-area pickup is slightly more competitive on price and available from most major brands including Hertz, Avis, and Budget alongside locally operated companies. Local Guam rental companies often offer lower daily rates than international brands with equivalent vehicle quality. Booking at least one week in advance is recommended during peak season (December–March), when popular vehicle classes — SUVs and minivans for families — sell out quickly.
Roads in Guam are well-maintained in Tumon, Tamuning, and on the main Route 1 coastal highway — but can narrow significantly in southern villages. GPS or Google Maps navigation is reliable across the island. Fuel prices are similar to US mainland levels. Parking is generally available and free at malls, beaches, and most attractions. The drive from Tumon to the southern tip of the island (Merizo) takes around 45–50 minutes via Route 4; the northern loop to Ritidian Point takes 35–40 minutes from Tumon. Rush-hour congestion occurs on Route 1 between Tamuning and Hagåtña on weekday mornings (7–8:30 AM) and evenings (4:30–6 PM). Seatbelt use is mandatory for all passengers.

questions & answers
Do I need a car in Guam?
For visitors staying only in Tumon and doing organised tours, a car is optional — everything in Tumon is walkable and taxis cover the main strip. However, for anyone wanting to explore southern villages, visit Ritidian Beach, discover local restaurants in Tamuning, or visit WWII historical sites, a rental car transforms the experience. Most visitors who rent a car cite it as one of their best decisions.
What side of the road does Guam drive on?
Guam drives on the right side of the road, the same as the US mainland. Speed limits are in miles per hour. Japanese and Korean visitors accustomed to left-side driving should take extra care at intersections. Roads are generally well-maintained, though rural southern routes can be narrow. An international driving permit is required for foreign licence holders.
How much does car rental cost in Guam?
Car rentals in Guam typically cost $35–$70/day for a compact or economy car, $50–$90/day for a mid-size sedan or SUV, and $70–$120/day for full-size SUVs or minivans. Rates are lower through local companies than major international brands. Weekly rates offer significant discounts — often 20–30% below the daily rate multiplied by seven. Always check if insurance is included, as Guam rental companies often offer collision damage waivers separately.
