There are three arches in Natural Bridge National Monument. The
trail to the Sipapu Bridge is the steepest one in the park. To go
there you must hike down by grabbing several metal bars and climbing
three wooden ladders, but most hikers can do it. On the way to the
bridge there are many erosions that form interesting patterns.
Sipapu bridge is the world's second largest natural bridge (The
largest one is Rainbow Bridge in Lake Powell). In Hopi's legend, "sipapu"
is the gateway through which souls pass from this world to another
world.
