Getting There
This area is located between El Segundo and Whitney Portal Buttress directly above the switchback of the Whitney Portal Road. Best approached from the Wood Road, as with Premier Buttress. 35 minutes.
The Classics
Mountain Project's determination of some of the classic, most popular, highest rated routes for Hairpin Wall:
The route seemed a little stiff for 5.9, more like easy 5.10. And it doesn't really need an 'R' qualifier. The protection and belay bolts on the first pitch (the best one) have been replaced. Should only get three stars.
