About Guam

Guam, a tropical island in the western Pacific Ocean, is the largest and southernmost of the Mariana Islands and a vibrant U.S. territory known for its stunning beaches, rich Chamorro heritage, and strategic geopolitical role.

The island spans roughly 30 miles long and 4–6 miles wide, featuring limestone plateaus, volcanic hills, and the striking limestone cliffs of the Tumon Bay coastline; its interior is dotted with dense tropical rainforests, hidden waterfalls, and the iconic Mount Lamlam, the highest point in Guam, rising 1,332 feet above sea level.

Guam's culture blends ancient Chamorro traditions with Spanish, American, and Asian influences, evident in its lively festivals like the annual Liberation Day parade, the traditional latte stone architecture, and a cuisine that fuses fresh seafood, pork adobo, and the beloved kelaguen dish, all enjoyed to the rhythm of island drums and modern pop.

A pivotal moment in Guam's history occurred on July 21, 1944, when American forces liberated the island from Japanese occupation during World War II, an event commemorated each year as Liberation Day and marking the island's transition to becoming an important U.S. strategic outpost in the Pacific.
