Guam May Be Far In Miles, But It’s A Lot Like Home

One of the nice things about Guam is that it is a territory of the United States, and most travelers from the USA will feel right at home.

And no, you don’t need your passport if flying through Hawaii. But it’s good to have.

However, if you are not from the US, read our article, “Do I Need a Visa To Tour Guam?”


  • English and Chamorro are the official languages, with some Spanish spoken. Tour guides will frequently also speak Japanese or Korean.
  • Guam was Spanish territory for over 300 years, which is why Chamorro sounds so much like Spanish. 85% of the population is Catholic.

Electricity & Communications:

  • You won’t need electrical adaptors coming from the mainland; Guam uses the standard socket for 110V.
  • Your cell phone provider will almost certainly charge steep roaming fees, so take advantage of the readily-available WiFi, and make your calls on Skype or FB Messenger.

Before You Come:

  • Make sure you are up-to-date on all vaccines.
  • Consider also getting vaccinated for Hepatitus A and Typhoid (recommended by the CDC.)

Bring Contact Information for:

  • A friend or relative at home.
  • All doctors / health care providers.


  • We hope you won’t need it, but you’ll find Guam Memorial Hospital in Tamuning, a full-service hospital with 158 beds and 24-hour emergency services.
  • Bring a Travel First Aid Kit, including:
    • Prescription medicine and copies of prescriptions in case medicine gets lost.
    • Health insurance card or documented supplemental travel health insurance.
    • Glasses or contacts, or both, if you need them.
    • Sunscreen, insect repellent. Sunglasses & hat.
    • Aloe gel for sunburn. Hydrocortisone cream in case of bug bites or rash.
    • Antacid. Diarrhea medicine. Mild laxative. (You don’t want to be hunting for these in the middle of the night!)
    • Condoms, if desired. (They are hard to get in Guam, due to the Catholic influence noted above.)
    • Decongestant/antihistamine. Cough suppressant.
    • Bandages, antibacterial ointment, and hand sanitizer.
    • Acetaminophen, aspirin, or ibuprofen.
    • Consider adding a mild sedative, in case of jet lag.

Entering & Exiting Guam:

  • If you are coming from the mainland & flying through Hawaii (meaning, you’re in the USA the entire journey), US citizens can travel to Guam without a passport. However, it is recommended that travelers without a passport bring a government issued photo ID and copy of their birth certificate.
  • Entry requirements for non-U.S. citizens are the same as for entering the United States from any foreign destination.
  • Upon departure, a passport is required for all but U.S. citizens.


  • Currency is in US dollars.
  • ATMs are common throughout Tumon, and virtually all larger establishments accept major credit cards.
  • Hotels, banks, and money exchangers can exchange money for a fee.
  • Sales tax of 4% is included in the price of most goods and services.


  • 10%-15% gratuity is usually added to your restaurant bill. (Check to confirm the exact amount.)
  • You may add more for exceptional service.
  • Many people also tip: bellmen, porters, hotel maids, taxi drivers & tour guides.
