Walnut Canyon National Monument preserves remarkable cliff dwellings built by the Sinagua people over 800 years ago in a dramatic limestone canyon near Flagstaff, Arizona. Managed by the National Park Service, the monument protects more than 80 rooms built into natural alcoves in the canyon walls, showcasing the ingenuity of ancient Puebloan architecture. Visitors can explore these well-preserved ruins via the Island Trail, which provides close-up views of the cliff dwellings and insights into the daily lives of the Sinagua culture. The monument also protects diverse plant and animal communities that thrive in the unique canyon ecosystem.
