A mile or so before you get to Boulder Basin Campground, there is a switchback in the road, with a large turnout and many many boulders sitting on either side of the road. Upper OK Corral features boulders tucked away from the sight of passing drivers, featuring many challenging problems.
Getting There
Roughly 5 miles from Highway 243 on Black Mountain Road and 1 mile before arriving at Boulder Basin Campground is OK Corral Right. Park in the turnout at the apex of the switchback. Walk uphill and behind the large set of boulders sitting just past the apex of the switchback if going to Boulder Basin.
