Guam National Wildlife Refuge (NWR) hosts a unique and fragile blend of native plants and animals found nowhere else in the world. It stands as a special place and source of pride for all. Here at Guam NWR, the U.S. Fish and Wildlife Service works with others to conserve and restore the precious resources of both land and sea. Guam’s native wildlife flourish in the native limestone and coastal forests, and sea creatures are bountiful in the tropical blue waters. Visitors seek out the beauty and tranquility provided and enjoy seeing and learning about wildlife. The Refuge is a vital link between Guam’s cultural and natural heritage, a vibrant reminder of the place nature holds in all our lives and a treasure for future generations.


Refuge Highlights:

  • Our Scenic Overlook, located on route 3A prior to the refuge entrance, offers unrivaled views overlooking the refuge and beyond. On a clear day the neighboring island of Luta (Rota) may be visible just off in the distance.
  • The Nature Center features interpretive murals depicting Guam’s natural environment before European contact 500+ years ago.
  • Visitors can explore 2 miles of trails through the majestic jungle and historic coconut grove, along which they can see a Spanish stone well, latte stones, and the site of the historic Spanish church, Casa Real.
  • Ritidian’s beautiful white-sand beach invites visitors to relax and enjoy its crystal clear waters. Note: There are no lifeguards on duty. Swim at your own risk. For visitors' safety, we ask that you use personal flotation devices for water activities, stay close to shore, avoid cuts in the reef, be aware of rip currents and what to do if you get caught in one, and do NOT go beyond the reef.
  • Visitors can participate in tours, including a cave tour to view pictographs, ancient pottery pieces and latte stones—a symbol of the Native Chamorro (Chamoru) people—and a tour an ancient latte village to experience an ancient Chamorro (Chamoru) village, untouched since the seventeenth century. See Events for upcoming tour dates.


A 2-mile loop down the forest road and returning along the beach is available to hikers.

Hiking is not allowed east of Ritidian Cut. The coral reef, beach, and forest east of Ritidian Cut and the Nature Center are closed to the public for the protection of marine life and forest wildlife.
