Wilderness Landscape & Natural Heritage
The Guam National Wildlife Refuge is a critical habitat located on the island of Guam, providing protection to various native species that are found exclusively on the island. Encompassing both the Ritidian Unit and a series of submerged lands, the refuge is characterized by limestone cliffs, beaches, and coral reefs, fostering biodiversity within its boundaries. The refuge plays an integral part in conserving the habitats of the endangered Mariana fruit bat, Guam rail, and other rare species. Historically, Guam was an important strategic location during World War II, and remnants of this era can still be observed around the island. Visitors can explore hiking trails that offer stunning vistas of the Pacific Ocean and the island’s interior landscapes. Engaging in wildlife observation, particularly bird watching, is a highlight, with opportunities to see species that are found nowhere else on earth. The refuge is also home to some of the oldest cultural and archaeological sites on Guam, supplying plenty of historical intrigue for visitors.
