The Four Corners is the only location in the United States where four states come together at one place. Arizona, New Mexico, Utah, and Colorado meet at the Four Corners. Here, a person can put each of their hands and feet in four states at the same time. The unique landmark is on Navajo Nation land and is open for visits from the public.

Originally surveyed and established by the US Government Surveyors and Astronomers in 1868, The Four Corners Monument has been refurbished in 1992 with a bronze disk embedded in granite. Each of the state boundaries radiate from the disk and each state's seal rests within that state's boundary.

The Visitor Center is open year round. In the Demonstration Center, Navajo vendors sell handmade jewelry, crafts, and traditional foods. Picnic tables and restrooms are available. No water is available at the park. Services and accommodations within a 30-mile radius are limited to small cafes, grocery stores, and self-service gasoline stations. All amenities are available in larger communities in Utah, Colorado, and New Mexico.
