02Walnut Canyon National Monument

Hiking the trails of Walnut Canyon feels like stepping back in time. This beautiful area is home to a remarkably well-preserved pueblo that was once inhabited by the ancient Sinagua people. The trails are marked with educational exhibits to help you learn more about the history and geology of the area. Most of the trails are fairly short, but they can be strenuous so be sure to wear appropriate hiking clothes and bring plenty of water.
