I-15 passes west of the Park and connects with UT-9 and 17 to the Park. US-89 passes east and connects with UT-9 to the Park. The Zion Canyon Visitor Center is a short distance from the Park's South Entrance adjacent to Springdale. The Visitor Center at the Kolob Canyons entrance is accessible from I-15, exit 40.
BY RV/COACHES/TRAILERS/ALL LARGE VEHICLES:
Drivers of large vehicles approaching Zion National Park from the east on UT-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, and some camper shells will require an escort.
(Note: It is possible to visit Zion with a large vehicle without going through the Zion-Mt. Carmel Tunnel. To do this enter and exit through the south entrance of the park, near Springdale).
Visitors requiring an escort must pay a $15 fee per vehicle in addition to the entrance fee. Pay this fee at a park entrance before proceeding to the tunnel. The fee is good for 2-trips through the tunnel for the same vehicle during a 7-day period.
*Vehicles over 13 feet 1 inch tall.
*Vehicles carrying hazardous materials. *Vehicles weighing more than 50,000 pounds. *Single vehicles over 40 feet long.
*Combined vehicles over 50 feet long.
