Guam National Wildlife Refuge

Guam National Wildlife Refuge was established in 1993, to protect and recover endangered and threatened species, protect habitat, control non-native species with emphasis on the brown tree snake, protect cultural resources, and provide recreational and educational opportunities to the public where possible. The refuge receives over 90,000 visits a year from island residents and tourists.

The Ritidian unit is located along the northernmost point of Guam.

Access the unit along Route 3A from the Route 9/Route 3 interchange approximately 6 miles from the refuge headquarters. Travel north on Route 3A for 4.5 miles, then turn left and continue downhill 1.5 miles to the refuge.
