||From Keystone, drive toward Mt. Rushmore on highway 16a and turn left on 16a when the road junctions with 244. Drive 3.1 miles and park on the shoulder of the road where a small, unnamed paved road intersects with the main highway on the right. This is about 1/4 mile after driving through the second tunnel.
There are two major areas here. The main area involves walking diagonally away from the intersection to the southwest on a faint trail. Although this trail is often difficult to follow, if you continue in that direction you will find the area. Head up a gradual incline on to slabby rocks, then at the top you will get to a viewpoint where you can see Turtle Rock to the left. Turtle Rock can be identified by its large slabby 3rd class rock on its north side. Hike down to this to find the main rocks and bouldering. The second area is across the road to the east. From the intersection, find a trail that heads steeply up the hill and quickly arrive at Rubik's Ridge, identified by the overhanging schist at the bottom of the cliff.
