The Zion-Mt. Carmel Tunnel is 1.1 miles long. It was blasted and cut in the thick Navajo sandstone during the early 1900s. The task of cutting through 2,000 foot thick sandstone, in those days, was not easy and was considered to be an engineering marvel. Blasting was used to enlarge the hole and railcars hauled off the debris. On the tunnel's south side, working on the tunnel was not any easy task because the drop off to the canyon below is 800 ft.
RV/Coaches/Trailers/All Large Vehicles
Drivers of large vehicles traveling through Zion National Park on Utah State Route 9 need to be aware of the large vehicle size restrictions.
Vehicles sized 7'10'' in width or 11'4'' in height, or larger, are required to have an ''escort" (traffic control) through the Zion-Mt. Carmel Tunnel. Vehicles this size are too large to stay in their lane while traveling through the tunnel. Nearly all RV's, buses, trailers, 5th wheels, dualie pick up trucks, and some camper shells will require an escort.

Wir haben den privaten Campingplatz benuetzt und fast wieder den selben Platz am Bach bekommen, wir vor 7 Jahren
Die Wanderung zum Hidden Canyon war sehr schoen. Kaum Menschen und tolle Aussicht.

Nach ein paar Tagen bin ich aufgewaermt und ready for the road again.
