Monument Valley is one of the truly iconic places of the United States. It has been the setting for hundreds of Western movies, and its unique sandstone formations are instantly recognizable the world over.
The Valley is home to Navajo families that have lived there for generations.
Monument Valley is a part of the Navajo Nation. It is located on the Utah/Arizona border, east of Highway 163. The park entrance is in Utah. Admission to the park is $5 per person, and free for children under the age of 9.
For visitor information, contact Monument Valley Navajo Tribal Park.
The park is open daily from 6am to 8pm from May through September and from 8am to 5pm from October through April.
From Flagstaff, head east on Highway 40 to Highway 89 (Page, Grand Canyon Exit). Travel north on Highway 89 to Highway 160. Travel east on Highway 160 to Highway 163 (Kayenta exit). Travel north into Utah to Goulding’s Lodge then take Indian Route 40 southeast to the entrance to Monument Valley. The closest airport is Farmington, New Mexico. It is about two and a half hours east of the park.
Most of the scenic locations within Monument Valley are found within the Monument Valley Navajo Tribal Park. At the edge of the valley, there is a visitor center, a small convenience store and the Haskenneini Restaurant, which specializes in both native Navajo and American cooking.
As this is not a federal park, National Park Passes or Golden Eagle Passes are not valid here.
“It’s breathtaking. You can’t believe it. It’s very photogenic; it has a kind of mythic feeling of age, of legend. . . . You’ve seen it in the movies, but when you see it in life, it’s so epic in its proportions that it almost stands for the whole of the West.” -Filmmaker Peter Bogdanovich.
