The east section of the park is a land of sandstone slickrock, hoodoos, and narrow canyons. You can see much of the dramatic scenery along the Zion–Mount Carmel Highway (Hwy. 9) between the East Entrance Station and Zion Canyon. Most of this region invites exploration on your own. Try hiking a canyon or heading up a slickrock slope (the pass between Crazy Quilt and Checkerboard Mesas is one possibility).
Highlights on the plateau include views of the White Cliffs and Checkerboard Mesa (both near the East Entrance Station) and a hike on the Canyon Overlook Trail [1] (it begins just east of the long tunnel). Checkerboard Mesa’s distinctive pattern is caused by a combination of vertical fractures and horizontal bedding planes, both accentuated by weathering.
The highway’s spectacular descent into Zion Canyon goes first through a 530-foot tunnel, then a 5,600-foot tunnel, followed by a series of six switchbacks to the canyon floor.
