Welcome to Walnut Canyon National Monument
Walnut Canyon is open year round from 9 a.m. - 5 p.m. (except December 25 and January 1). Access to viewpoints of the canyon, and the park trails are not accessible after 5:00 p.m.
Leave I-40 at Exit 204, 7.5 miles (12 km) east of Flagstaff; drive south 3 miles (5 km) to the canyon rim. Warning: Tight turn around for towed vehicles; 40 feet (12 meters) maximum length advisory.
Not all of Arizona is warm dry desert. Weather can vary widely, especially with elevation.
At Walnut Canyon (6690'/2039m above sea level), be prepared for snow in winter, hot sun in summer with afternoon thunderstorms, and, especially in spring, strong gusty winds on the rim and/or in the canyon. Best advice - dress in layers, because the weather can change quickly at any time of year.
Leashed pets are allowed on the Rim Trail and in the visitor center parking lot. Pets are not permitted in the visitor center or on the Island Trail. Please clean up after your pet.
NOTE: Summer heat is intense; pets left in vehicles - even for a short time - can suffer heat stroke and die.
