Natural Bridges National Monument preserves some of the finest examples of natural stone architecture in the southwest. On a tree-covered mesa next to deep sandstone canyons, three natural bridges formed when meandering streams slowly cut through the canyon walls. The trail to Owachomo is the easiest, though all trails may be hiked by children with appropriate supervision. Kids also enjoy the short interpretive talks and walks offered spring through fall.
