The Zion - Mt. Carmel Tunnel is located on the park
road between the East Entrance and Zion Canyon.
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
because they are too large to stay in their lane while
traveling through the tunnel. Nearly all RV's busses,
trailers, 5th wheels, and some camper shells will
require an escort.
Visitors requiring an escort must pay a $10 fee per
vehicle (subject to change in 1997), in addition
to any entrance fee. Pay this fee at either park
entrance before proceeding to the tunnel. The fee
is good for two trips through the tunnel for the same
vehicle during a 7-day period.
