Rocky Mountain Arsenal National Wildlife Refuge
The Rocky Mountain Arsenal northeast of Denver, Colorado occupies more than 15,000 acres and has many easy hiking trails and a self-guided Wildlife Drive auto tour. Visitor activities include wildlife observation, photography, environmental education, nature programs, and fishing. You may see over 330 species of wildlife there. Trails and Wildlife Tour map Although I have been told there are ADA-compliant trails there, the brochure only gives the lengths of the many short trails. Location map
