One overlook we decided we couldn't miss on the way out was the Head of the Rocks Overlook.
From A Route Guide to Scenic Byway 12
Head of the Rocks Overlook provides expansive views out across the Escalante Canyons where colorful slickrock stretches almost as far as the eye can see. Some 168 million years ago, these striated cream-and-red sandstone formations were sand dunes. In the distance one can see the southeastern edge of the Aquarius Plateau (i.e. Boulder Mountain) to the north, the Henry Mountains ... to the east, and Navajo Mountain and the eastern edge of the Kaiparowits Plateau to the south and west.
