Visit the Refuge

Guam National Wildlife Refuge, Ritidian Unit welcomes the public free of charge. Visitors can explore roughly two miles worth of trails, visit latte stone and other cultural sites, relax on a beautiful white-sand beach, or schedule a tour of the numerous caves found along the limestone cliff line. Visitors can also experience what Guam may have looked and sounded like 500 years ago, by visiting our Nature Center building, where four 16-foot murals depict Guam’s natural environment before European contact. Disclaimer:  There are no lifeguards on duty and ocean currents can be very strong. Stinging jelly fish (Man of war) are also occasionally found . Therefore, caution and the use of life-jackets is highly recommended for water activities. For other tips and safety suggestions, we recommend checking out our Plan Your Visit page.
