The three bridges in the park are named Kachina, Owachomo, and Sipapu (the largest), which are all Hopi names. A natural bridge is formed through erosion by water flowing in the stream bed of the canyon. During periods of flash floods, particularly, the stream undercuts the walls of rock that separate the meanders (or "goosenecks") of the stream, until the rock wall within the meander is undercut and the meander is cut off; the new stream bed then flows underneath the bridge.

The bridges and other features present on the Colorado Plateau today were molded by the processes of erosion. The destructive forces of wind and rain, running water, and freezing temperatures attacked the uplifts as soon as all the tectonic havoc started in the Late Cretaceous. The Colorado Plateau has been uplifted about 12,000 feet (3,660 m) since the end of the Cretaceous about 66 million years ago.

The main attractions are the natural bridges, accessible from the Bridge View Drive, which winds along the park and goes by all three bridges, and by hiking trails leading down to the bases of the bridges. There is also a campground and picnic areas within the park. Electricity in the park comes entirely from a large solar array near the visitors center.

In 2007, the International Dark-Sky Association named Natural Bridges the first International Dark-Sky Park, which is a designation that recognizes not only that the park has some of the darkest and clearest skies in all of the United States, but also that the park has made every effort to conserve the natural dark as a resource worthy of protection.

Horsecollar Ruin is an Ancestral Puebloan ruin visible from an overlook a short hike from Bridge View Drive. The site was abandoned more than 700 years ago but is in a remarkable state of preservation, including an undisturbed rectangular kiva with the original roof and interior, and two granaries with unusual oval shaped doors whose shape resembles horse collars.
