The Zion Mt. Carmel Hwy (UT 9) is a gorgeous
scenic drive with beautiful views of the Zion Canyon and the
red-colored sandstone of the surrounding peaks. Enjoying the fine
views comes with a price, the road is steep and narrow with hairpin
switchbacks and a surprise in the form of a narrow tunnel. The
tunnel is so narrow that escorts must accompany oversized vehicles.
There is no light in the tunnel, which is 1 mile long, but there
are windows cut into stone which allow views of the peaks outside
(just make sure the driver isn't watching). The tunnel was carved
through the stone in the early 1900's when the technology available
for such projects was in its infancy. There are turn-offs along
the highway, where you can stop and enjoy the views (no stopping
in the tunnel, though).
