Other signs identify natural features such as the many different types of trees that live in the canyon, including the Arizona black walnut, the canyon's namesake. The Rim Trail is another feature at Walnut Canyon. Also a paved route that is 0.7 miles long, it passes a picnic area, and many rim-top structures the Sinagua left behind. Walnut Canyon is located just east of Flagstaff, and is a popular destination for outdoor activities such as hiking, hunting and biking, most of which are allowed only in the western part of the canyon. To reach Walnut Canyon National Monument, travel 10 miles east on Interstate 40 from Flagstaff, and take exit 204.
Signs clearly point the way to the visitor center.
The monument offers other off-trail hikes guided by park rangers on a regular basis.
