The Arboretum at Flagstaff is a 200 acre (800,000 m²) arboretum that is home to 2,500 species of drought-tolerant native plants representative of the high-desert Colorado Plateau, home to the Grand Canyon and Zion National Park. It is located 3.8 miles (6 km) south of Route 66 on Woody Mountain Road, on the west side of Flagstaff, Arizona.
The Arboretum was originally forest and a working ranch, and the home of Frances McAllister in the late 1960’s. In 1981, she began her long-held dream of creating an arboretum when she donated the land and created its endowment.
