Dark Canyon Primitive Area TH, UT It was getting dark with no campsite to be found when we rounded a curve and found this perfect overnighting site west of Blanding, UT in the Manti-La Sal National Forest. This is one of the jumping-off points for the Dark Canyon Primitive Area. From Blanding, go west on Utah 95 to Utah 275. Drive about 1 mile on UT 275 to Bears Ears Road(228 RD). Follow the main dirt road up to this wooded plateau. Note: Parts of the road may be muddy at certain times of the year and may require 4WD. The roads are 2WD when dry.
