A rental car is the most flexible way to explore Guam beyond Tumon. The island's main road — Marine Drive and Route 1 — is straightforward to navigate, and most destinations are within a 30-minute drive of Tumon. Rental desks are located at Antonio B. Won Pat International Airport and at several hotels in Tumon. A valid driver's licence from your home country is accepted; an International Driving Permit is recommended but rarely required in practice. Drive on the right; speed limits are in miles per hour.
why this category matters
Car-rental usefulness depends on island layout: essential in some places, optional in others, and actively inconvenient in dense walkable resort zones.
The best listing is often the one with the cleanest pickup/drop-off logistics, not the lowest headline day rate.
This category should usually be evaluated alongside your hotel base and itinerary shape, not as a standalone bargain hunt.
planning notes
A rental car is strongest when your trip includes scattered beaches, villages, early starts, or island loops that would be awkward by taxi or tour pickup. If you are staying in one dense resort area and mostly walking, the category may still be useful but not essential.
Check airport access, insurance clarity, fuel rules, and where you will actually park. The cheapest listing can become the weakest option if pickup is inconvenient or if your itinerary does not justify the fixed hassle of having a car every day.
questions & answers
Do I need an International Driving Permit (IDP) to rent a car in Guam?
Most rental companies in Guam accept a valid national driver's licence for Japanese, Korean, and other international visitors without requiring an IDP. However, it is advisable to carry one as a backup since individual company policies vary. IDPs are available from national automobile associations in your home country.
How much does a rental car cost in Guam?
Basic compact cars start from around USD $40–60 per day for walk-in rates; advance online booking can reduce this significantly. SUVs and larger vehicles cost $70–100+ per day. Fuel is priced similarly to mainland United States. Most rental agreements include basic liability insurance; check whether your credit card provides collision damage waiver (CDW) coverage.
