Guam Travel Information
Electricity in Guam is 110/120 volts, 60Hz. Two-prong, flat-blade plugs are standard.
English and Chamorro are the official languages of Guam.
Although no vaccinations are required for travel to Guam, hepatitis A and hepatitis B vaccinations are recommended for all travellers. A Japanese encephalitis vaccination is recommended for those planning to spend time in rural areas or outdoors. An MMR (measles, mumps, rubella) vaccination is recommended if not previously given.
Do not drink tap water in Guam unless it has been boiled, filtered, or chemically disinfected, and don't have ice in your drinks. There are medical facilities available on the island but for life-threatening injuries or diseases you may well need to be transferred overseas to receive treatment; comprehensive travel insurance is recommended. It is best to bring along any medication you require, with a signed and dated letter from your doctor detailing the medication you need and why.
Trips to Guam are usually trouble free but travellers should take precautions to protect themselves against petty theft and pickpocketing. Make sure you have duplicate copies of your travel documents and don't carry all your valuables in one pocket or bag. Make use of hotel safes and don't flash wealth.
The urban population of Guam is diverse and generally accepting, but modest clothing is always good etiquette. The native Chamorro people are predominantly Catholic, and respect for the elderly and authority figures is crucial.
