Viewpoint Overlooking Ritidian Beach in Guam National Wildlife Refuge

The Ritidian Unit of Guam National Wildlife Refuge, known to the Native Chamorro people as Puntan Litekyan, is located on the northern tip of Guam and encompasses approximately 1,217 acres, including 385 terrestrial acres and 832 acres of submerged areas offshore.

The Ritidian Unit was established in 1993, in response to the 1984 listing of six species as endangered, and was designated critical habitat in 2004 for three of these species: the Mariana fruit bat, the Guam Micronesian Kingfisher, and the Mariana crow.
