Wilderness Landscape & Natural Heritage
Located just northeast of Denver, Colorado, the Rocky Mountain Arsenal National Wildlife Refuge spans reclaimed land once part of a chemical weapons manufacturing site. Transformed over decades, the refuge now covers over 15,000 acres of prairie, wetlands, and ponds, providing critical habitat for more than 330 species of wildlife, including bison, deer, coyotes, and over 190 bird species. The area plays an important ecological role as one of the largest urban refuges in the United States. Visitors can explore more than 20 miles of multi-use trails for hiking, biking, and wildlife observation, with seasonal guided tours and educational programs available. Significant landmarks include the bison herd enclosures, the waterfowl viewing areas, and several historic structures reminding visitors of the site's former military use. The refuge’s proximity to Denver offers a unique opportunity to experience nature, wildlife photography, and interpretive activities without traveling far from the city. It is managed by the U.S. Fish and Wildlife Service, emphasizing habitat restoration, public education, and coexistence between urban development and wildlife conservation.
