Natural Bridge State Monument

  • Geological Site

Fodor's Review

At Natural Bridge State Monument the Boulder River disappears underground, creating a natural bridge, then reappears as roaring falls in the Boulder River canyon. Hiking trails and interpretive signs explain how this geologic wonder occurred. The Main Boulder Ranger Station, a few miles past the bridge, is one of the oldest in the United States and is now an interpretive center.
