One of three national monuments near Flagstaff, Arizona, Walnut Canyon is rich in the early history of Indigenous peoples.
Walnut Canyon has been inhabited off and on for thousands of years, but about 800 years ago, the Sinagua (without water) people stayed and made a mark.
Today, we can walk in their footsteps and wonder at how they used this steep canyon as their home. Archaeologists estimate that at its peak during the 1100s, Walnut Canyon could have been home to anywhere from 50 to 400 people. Early residents built pit houses and pueblos, some atop the “island” formed by a sharp meander in Walnut Creek.
The Island Trail, which includes more than 700 steps, provides visitors with a glimpse into the lives of the Sinagua people, ancestors of some of today’s Pueblo tribes, such as the Hopi and Zuni.
Geology of Walnut Creek
During the Permian age, about 250 million years ago, this area was beachfront property. The sandstone you see today at the bottom of the canyon, the Toroweap Formation and Coconino Sandstone, was once windblown dunes. The hard rim rock atop the canyon is the Kaibab Formation, which also forms the surface of the Grand Canyon.
Not far from Walnut Canyon National Monument is Sunset Crater National Monument.
When Sunset Crater was formed by a volcanic eruption between 1040 and 1100 CE, people living in that area lost the homes and farmlands they had used for centuries.
The Sinagua people began searching for new homes in places like Walnut Canyon.
History of the Ancient Cliff Dwellings
When you visit, you’ll see the remains of stone walls, some of which have been reconstructed. But when the Sinagua people lived in Walnut Canyon, the walls were plastered and floors leveled with clay. These rooms were used for storage, sleeping, and working during inclement weather.
Like other Puebloan people, they would farm on the rim of the canyon, live on ledges in the center, and gather water and hunt at the bottom of the canyon at the creek. They used pottery vessels to store snow and water for use during the dry season. Today, Walnut Creek seldom has water as it has been dammed, and the water is diverted for use in Flagstaff.
The limestone overhang provides shelter for the dwellings below. Building under these ledges provided a roof, back wall, and a floor already in place.
They only had to construct side walls and a front wall with a door, which could have been covered with animal skins, woven sticks, or cotton cloth.
An opening under the door and a window above provided air circulation to draw smoke from the cooking fire up and out.
If you enjoy visiting the pueblos at Walnut Canyon, be sure to visit nearby Wupatki National Monument, where the largest freestanding pueblo in northern Arizona can be found.
Exploring Walnut Canyon National Monument
Walnut Canyon National Monument is located about 7.5 miles east of Flagstaff. From Interstate 40, go south from exit 204, and the visitor center is just three miles down the road.
For those traveling with long RVs, be aware that the parking area has limited turnaround space. The National Park Service recommends a length limit of 40 feet.
The monument is open daily from 9 a.m. to 5 p.m., although it closes at 1 p.m. on Thanksgiving, Christmas, and New Year’s Day.
Walnut Canyon National Monument Tickets
If you have an annual pass or an America the Beautiful Pass, you’re all set to visit Walnut Canyon National Monument. If you don’t have one of these passes, entry tickets cost $25 for everyone in a private car (it’s good for seven days), $20 for a motorcycle, and $15 if you come by bike or foot.
You can also purchase an annual pass that gets you unlimited entry to the three national monuments near Flagstaff for $45.
Note that Walnut Canyon is cashless for admission fees, accepting credit and debit cards or electronic payments only. The store at the visitor center does accept cash, however.
There are more passes available for national parks and monuments you may want to consider.
Weather at Walnut Canyon
At 7,000 feet in elevation, weather conditions can change rapidly, so dressing in layers is always recommended. Summer can bring temperatures above 90 degrees as well as monsoonal thunderstorms. It can snow at Walnut Canyon from winter into early spring, and it can be windy any time of year.
Check current weather conditions on the monument’s website.
Because the monument is at a high elevation, it is important to protect yourself from the sun and to stay hydrated. Wear sunscreen, a broad-brimmed hat, and sun-protective clothing. Take a water bottle with you, which you can refill at the visitor center.
Visitor Center
Walnut Canyon National Monument has a visitor center that includes a museum, film, Western National Park Association store, overlooks, and restrooms.
This is also where you can pick up a Junior Ranger activity book to complete and earn a badge. The best thing is that there is no age limit for being a Junior Ranger: adults are welcome to participate.
Walnut Canyon National Monument Hiking Trails
To get a close-up look at the cliff dwellings at Walnut Canyon, consider hiking the Island Trail, which plunges 185 vertical feet into the canyon and includes 736 stairs. It is considered a strenuous hike, especially when you consider that Walnut Canyon is situated at 7,000 feet above sea level.
Along the way, you’ll see 25 cliff dwelling rooms and be able to look across the canyon to even more.
Entry to the trail ends at 4 p.m. to ensure visitors are back from this one-mile round-trip excursion in time for when the monument closes at 5.
It is not wheelchair or stroller accessible due to the steep canyon terrain and stairs.
A much easier hike is the Rim Trail, which takes visitors along the canyon rim through a juniper and piñon pine forest. At the two overlooks, you can peer down at cliff dwellings below.
On the path, enjoy native plants, a demonstration garden, and a partially rebuilt pit house and pueblo. This trail is .7-mile long, and the section up to the first canyon overlook is paved and accessible.
Walnut Canyon National Monument does not offer any backcountry hiking trails and has no cycling paths. Whether you take the Island Trail or the Rim Trail, respect the history and culture you are exploring. Do not climb or lean on the dwelling walls, and do not take or disturb any features.

Wildlife at Walnut Canyon
The steep canyon walls create two distinct ecosystems: the sunny south side and the shadier north side. On the shady north side, you will walk amongst ponderosa pine and Douglas fir trees, while on the sunny south side, you’ll be in a piñon pine and juniper forest spotted with yucca and prickly pear cactus.
The canyon is home to wildlife diversity, particularly birds, many of which can only be found in a certain season and their preferred ecosystem.
In all, 160 species of birds have been recorded at Walnut Canyon, from tiny Bushtits and Mountain Chickadees to soaring Bald Eagles and Turkey Vultures.
The Mexican Spotted Owl, a threatened species, also makes its home at Walnut Canyon.
Mammals that migrate through or make their home at Walnut Canyon include pronghorn, javelinas, ringtails, bobcats, black bears, many species of bats, plus a variety of squirrels and chipmunks.
Of course, amphibians and reptiles can also be found here. Whether you find a garter snake or a bobcat, your best plan of action is to give the animal plenty of space.
Interpretive Programs
The rangers at Walnut Canyon lead some special hiking opportunities in summer, including exploring the historic Ledge Trail and the 1904 ranger cabin. The Ledge Trail has steep drop-offs, no handrails, 273 stair steps, and uneven footing.
It is limited to only five participants to protect the cliff dwellings that hikers will see along the way. The Ranger Cabin Hike is two-miles round trip and includes a cabin tour. Reservations are required for both of these hikes.
If you visit in March, you can participate in Arizona Archaeology and Heritage Awareness Month, with activities at all three of the Flagstaff-area national monuments: Wupatki, Sunset Crater, and Walnut Canyon. The program is coordinated by Arizona State Parks.
Accessible Features
The three-floor visitor center has an accessibility lift operated by staff, providing access to all levels of the facility. The entry and exit doors open automatically, and there are accessible restroom stalls. The film in the visitor center is closed-captioned. In addition, a wheelchair is available for loan.
Outdoors, there is a wheelchair-friendly picnic table on the accessible portion of the Rim Trail. The first 150 feet of the trail meets ADA accessibility standards, but beyond that, the trail is considered slightly steeper than standard.
ADA service dogs are allowed in the visitor center and on trails. (Please note that leashed pets are welcome on the Rim Trail, but not in the visitor center or Island Trail.)
In summer, when temperatures soar, the trails may be too hot for your dog’s paws.
Where to Stay
There are no campgrounds at the monument, but there are two nearby U.S. Forest Service campgrounds, both open from early May to mid-October with some sites by reservation and some first-come, first-served.
Check out Bonito Campground or Canyon Vista Campground through the Coconino National Forest camping website. Bonito is just outside the entrance to Sunset Crater and Wupatki national monuments. They both have toilets, but no showers or RV hookups.
Flagstaff is the nearest city and offers plenty of hotel options as well as private campgrounds.
