Natural Bridges National Monument Park

Rank: 239

Park Description

Three majestic natural bridges invite you to ponder the power of water in a landscape usually defined by its absence. View them from an overlook, or hit the trails and experience their grandeur from below. Declared a National Monument in 1908, the bridges are named "Kachina," "Owachomo" and "Sipapu" in honor of the Native Americans that once made this area their home.
