Natural Bridges National Monument covers a relatively small area in southeast Utah, close to scenic highway UT 95 between Hanksville and Blanding. It is rather remote and not close to other parks so is not heavily visited, despite being near many fine, lesser known places in this part of the state such as White Canyon, Cedar Mesa, Grand Gulch Plateau and the La Sal Mountains. There are only three bridges here, though the monument also contains Anasazi cliff dwellings, pictographs and white sandstone canyons. Natural bridges are formed by running water and hence are much rarer than arches, which result from a variety of other erosional forces. This is also the reason why bridges tend to be found within deep canyons, sometimes quite hidden, whereas arches are usually high and exposed, often the last remnants of cliffs and ridges.

The loop road (Bridge View Drive) has several overlooks of the three bridges, currently known as Sipapu, Kachina and Owachomo after their original names were changed to reflect the Hopi Indian history of the area. The last of these three is the most spectacular when seen from the road, and also the easiest to hike to - the path into the canyon underneath the bridge is only a few hundred yards. It is the oldest bridge in the park, and rock falls have reduced the thickness to only 9 feet, so it may not be here much longer. Needless to say, walking on top of the bridges is not allowed, though this would generally be difficult as the surrounding cliffs are tall and steep. Kachina Bridge is the most geologically recent of the three and is still being actively enlarged - 4,000 tons of rock fell from the north side in June 1992 - unlike the others which are now situated some way above the watercourses, however Kachina is difficult to spot from the highway, and requires the longest walk to reach. Although also quite far from the road, the first bridge (Sipapu) is in full view from the overlook, and presents an easily recognizable outline.
