Walnut Canyon National Monument, about 7.5 miles east of Flagstaff Arizona, preserves remarkable ancestral cliff dwellings built into limestone alcoves along the canyon walls. Indigenous peoples have lived and traveled through this landscape since time immemorial, and archaeologists use the term Sinagua to describe many of the ancestral communities that lived in the Flagstaff region. Visitors today can view the canyon from overlooks, walk the easy Rim Trail, or descend the strenuous Island Trail for close-up views of ancient dwelling rooms dating primarily from the 1100s and 1200s.

Ancient cliff dwellings built into Walnut Canyon limestone alcoves

Walnut Canyon stretches roughly 20 miles and reaches about 400 feet deep. Over millions of years, Walnut Creek cut through layers of sandstone and limestone, creating steep walls, ledges and alcoves. Those limestone alcoves later provided protected locations where ancestral residents constructed the cliff dwellings that visitors can still see today.

Walnut Canyon's geology records several ancient environments. Sandstone layers reflect an earlier desert landscape, while limestone near the canyon rim contains marine fossils from a later inland sea. Today the approximately 3,600-acre national monument protects not only important archaeological sites but also a diverse mixture of forest, canyon and riparian habitats.

During the 1100s, ancestral residents increasingly built homes in shallow limestone alcoves below the canyon rim. Families farmed corn, squash and beans on the surrounding uplands while using the canyon's plants, wildlife and intermittent water sources. The Walnut Canyon community remained active for roughly 150 years before residents gradually moved elsewhere in the region.

The ancestral communities of Walnut Canyon cultivated corn, squash and beans and made use of the canyon's varied natural resources. Archaeologists later grouped many Flagstaff-area sites under the term Sinagua, but the National Park Service notes that this is an archaeological classification rather than the historic name of a tribe. Thirteen federally recognized tribes are traditionally associated with the Flagstaff Area National Monuments today.

Walnut Canyon Cliff Dwellings & Ancestral History

Walnut Canyon Rim Trail

The self-guided Rim Trail is an easy, fairly level 0.7-mile round-trip walk along the canyon rim. Two overlooks provide views into Walnut Canyon and toward cliff dwellings below. Along the route, visitors can also see a partially reconstructed pithouse and pueblo. The first portion of the trail leading to the first overlook is paved and accessible.

Walnut Canyon Island Trail

The Island Trail provides the closest public access to Walnut Canyon's cliff dwellings. The approximately one-mile round-trip trail descends 185 vertical feet below the canyon rim and passes 25 cliff dwelling rooms, with additional sites visible across the canyon. The paved route includes numerous stairs and is rated strenuous, particularly for visitors not acclimated to the monument's approximately 7,000-foot elevation.

Allow about an hour for the round trip, carry water and wear sturdy shoes. The trail can close because of snow, ice or other conditions, and visitors must begin the Island Trail before its daily closing time.

Walnut Canyon Ranger Programs

Walnut Canyon National Monument periodically offers ranger-led interpretive programs and special hikes. One example is the reservation-only Ledge Hike, which follows an unmaintained route past sensitive archaeological sites and is limited to a small number of participants. Program dates, times and availability vary, so visitors should check the current National Park Service schedule or contact the Walnut Canyon Visitor Center before planning a ranger-led activity.

Walnut Canyon National Monument was established by President Woodrow Wilson on November 30, 1915, to protect ancient cliff dwellings and other archaeological resources from further damage and looting. The monument was initially administered by the U.S. Forest Service and was transferred to the National Park Service in 1934.

Walnut Canyon National Monument is currently open daily from 9:00 AM to 5:00 PM, except for scheduled holiday closures. The Island Trail closes to new hikers at 4:00 PM, and visitors should begin the Rim Trail by 4:30 PM so they can return before the park closes.
