Although Guam is a compact island, public transportation is almost non-existent, so opting for a rental car is one of the best ways to get around. A popular route is to drive south to Merizo and the Inajaran Pools. Also, many of the island’s quietest and most beautiful beaches are only accessible by road.
Despite its small size, navigating in Guam can be difficult, especially off the major coastal highways. Most rental companies offer customers the option of adding a GPS or mobile Wi-Fi package onto their rental, allowing for easy navigation without expensive roaming charges. Budget offers both options, a portable GPS system costing around $7.50 per day and mobile Wi-Fi for up to 5 devices costing approximately $8 per day.
Children under the age of 12 must be seated in an age-appropriate restraint that is placed in the rear seats of the vehicle.

A daily fee is usually applicable for this service, such as $10 per day with the rental agency Avis.
Those who wish to rent a car in Guam but are starting their trip with a few days in Tamuning may find it best to pick up their car from a city center location.
