Zion–Mount Carmel Highway and Tunnels
Zion–Mount Carmel Highway and Tunnels Review
Two narrow tunnels as old as the park itself lie between the east entrance and Zion Canyon on this breathtaking 24-mile stretch of Route 9. One was once the longest man-made tunnel in the world. As you travel the (1.1 mile) passage through solid rock, five arched portals along one side provide fleeting glimpses of cliffs and canyons. When you emerge into the daylight you'll find that the landscape has changed dramatically. Large vehicles require traffic control and a $15 permit, available at the park entrance, and have restricted hours of travel. This includes nearly all RVs, trailers, dual-wheel trucks, campers, and boats. The ½-mile Canyon Overlook Trail starts from a parking area between the two tunnels. The road is open April through October.
