Visit the Refuge

Guam National Wildlife Refuge Ritidian Unit welcomes the public between the hours of 7:30 a.m. and 4:00 p.m. Visitors can relax on the Unit’s pristine beach, explore the two miles worth of trails, visit latte stone sites, or schedule a tour of the numerous caves found along the Refuge. Visitors can also experience what Guam may have looked and sounded like 500 years ago, by visiting our Nature Center (hours vary), where four 16-foot murals depict Guam’s natural environment before European contact.
