Guam, the westernmost territory of the United States, is located in the Pacific Ocean and is known for its strategic position, unique Chamorro culture, and beautiful beaches. The island blends American and Micronesian influences, offering visitors a mix of modern shopping, historic sites from World War II, and natural beauty ranging from coral reefs to waterfalls. Tourism, US military bases, and agriculture form the backbone of its economy.
Guam is the largest island in Micronesia, measuring about 48 kilometres long and up to 15 kilometres wide. The north is a limestone plateau covered with forest, while the south is volcanic with rugged hills and valleys. Surrounded by the Philippine Sea and Pacific Ocean, Guam features coral reefs, sandy beaches, and a mountainous interior dominated by Mount Lamlam, which rises 406 metres.
Antonio B. Won Pat International Airport serves as Guam’s gateway, with flights mainly from Asia, Hawaii, and the US mainland. Public transport is limited to a bus service, so most visitors rely on rental cars or taxis. Driving is straightforward, but distances can be deceiving due to hilly terrain and traffic in urban areas.
As Guam is a US territory, entry requirements are the same as for the United States. UK visitors generally require an ESTA or visa under the US Visa Waiver Program. Immigration procedures follow US federal law, and visas should be arranged before arrival. The nearest British Embassy is in Manila, Philippines.
The US dollar (USD) is the official currency. ATMs and card payments are widely accepted, though cash may be useful in smaller establishments. Goods and services tend to be more expensive than on the US mainland, as many items are imported.
Healthcare facilities are reasonable but limited compared to the US mainland. The main public hospital is Guam Memorial Hospital in Tamuning, with private clinics also available. Serious medical conditions may require evacuation to Hawaii or the Philippines. Mosquito-borne illnesses such as dengue and Zika occur, and the island is prone to powerful typhoons. Comprehensive travel insurance, including cover for evacuation, is essential.
