Zion-Mt. Carmel Tunnel

Completed in 1930, the Zion-Mount Carmel Tunnel was the longest tunnel in rural America, stretching 1.1 miles (1.8 kilometers) through solid rock. This engineering marvel serves as the unofficial gateway to the eastern side of Zion National Park, facilitating travel between Zion, Bryce Canyon, and the north rim of the Grand Canyon via the Zion-Mount Carmel Highway, a national historic landmark. Visitors can experience the tunnel’s impressive scale and the dramatic transition from one scenic landscape to another as they drive through.
