Three sport lines and one gear route comprise the hinterlands of the Hairpin Turn Area. These routes see relatively little traffic since they are further from the road.

The Tweener Wall is reached by hiking through the boulder and sand filled wash. Take the path of least resistance, following the faint climber's trail when visible. Watch the left side of the wash for a trail the rises out of the grass to the base of the cliff as you would to reach the Forehand Wall or the Left Hand Wall. Follow the trail north (right / away from the highway) and round a 90 degree corner turning to the left. Hike the scree-filled trail uphill past the Backhand Wall until encountering a faint trail leading north (right / away from the highway). Maintain elevation while hiking for a couple of minutes to reach the Tweener Wall.

The approach takes 20-25 minutes.
