Guam FAQLearn what Guam is known for, where to visit, how long to stay and what currency and languages travelers can expect.
What is Guam known for?
Guam is known for tropical beaches, clear Pacific water, coral reefs, duty-free shopping, Chamorro culture and significant World War II sites.
Tumon Bay is the main resort district, while the rest of the island offers scenic viewpoints, villages, waterfalls, hiking and historical locations.
What are the best places to visit in Guam?
Guam is one island and Tripmasters lists Guam Island as the principal destination, so visitors normally use a single hotel base or change resorts rather than build a multi-city itinerary.
How many days should I spend in Guam?
Approximately 4-6 days works well for a first visit, with additional time useful for diving, beach relaxation or a slower resort stay.
Tripmasters vacation packages are customizable, allowing travelers to select nights, hotels, transportation and activities in each destination.
What currency is used in Guam?
Guam uses the U.S. dollar (USD), since it is an unincorporated territory of the United States.
Which languages are spoken in Guam?
English and Chamorro are official languages. Filipino languages and several other Micronesian and Asian languages are also widely heard.
Best Time to Visit GuamCompare Guam’s drier and wetter tropical periods and account for the island’s exposure to Pacific tropical storms.
When is the best time to visit Guam?
The drier period generally runs from roughly January through June, while July through December is wetter. Tropical storms and typhoons are possible, with risk generally higher in the second half of the year.
January – March
Drier Season
Humidity is somewhat lower and rainfall is generally reduced, making this a popular period for beaches and sightseeing.
Best for: Beaches, snorkeling, road trips and outdoor activities.
April – June
Warm Transition
Hot conditions continue with increasing humidity toward the start of the wetter season.
Best for: Diving, beaches and island touring.
July – September
Wet Season
Rainfall, humidity and tropical-weather risk increase. Heavy showers can interrupt outdoor plans.
Best for: Flexible resort stays and value travel.
October – December
Late Wet / Transition
Typhoon risk can remain elevated before conditions gradually move toward the drier season.
Best for: Indoor-outdoor itineraries with weather flexibility.
Tipping in GuamUnderstand gratuities in restaurants, hotels, taxis and guided tours while traveling in Guam.
Is tipping customary in Guam?
Guam generally follows U.S. tipping practices more closely than most Asian destinations. Restaurant, hotel, taxi and tour gratuities are common when service is not already included.
Which currency should I use?
Use U.S. dollars.
Restaurants, cafes and bars
Around 15-20% is customary for table service when gratuity is not already included.
Hotel staff
Porters, housekeeping and valet staff are commonly tipped in U.S.-style amounts.
Taxi drivers
A gratuity of roughly 10-15% is customary for good service.
Tour guides
Guides, dive crews and activity staff commonly receive tips depending on service and trip length.
Check resort bills for automatic service charges before adding another gratuity.
Getting Around GuamA rental car is the most flexible way to explore Guam, supplemented by buses, trolleys, taxis and local ride services.
What is the best way to travel around Guam?
Guam has no passenger rail system. The island is small on a map but attractions are spread out, sidewalks are limited outside resort areas and public transportation is less comprehensive than in major Asian cities.
What should I verify before traveling?
- Drive on the right
- Carry a valid U.S. or accepted driving license as applicable
- Allow time for limited bus frequencies
- Check tropical-weather advisories before long outdoor days
- Do not plan on rail travel within Guam
- Use U.S. dollars for all ordinary payments
The legacy country page contained copied ferry information from St. Vincent; Guam has no regular inter-island passenger ferry system and should be planned around road transportation and air connections.
