About Lost Horse Wall

Lost Horse Wall is one of JTree's tallest single walls — a southwest-facing sweep of clean quartz monzonite about 300 yards from Lost Horse Road, downstream of Real Hidden Valley and the Brown Wall. Holds a concentration of the park's best moderate multi-pitch routes: Dappled Mare (5.8, 4 pitches) is the classic at the grade; The Swift (5.7, 3 pitches) is the easier intro; Bird on a Wire (5.10a, 3 pitches, established 1977) is a must-do winter moderate on Miramontes's must-do 5.10 crack list. The southwest aspect means it's sunny most of the day and dries almost immediately after the rare desert shower — ideal winter destination. Short approach from Lost Horse trailhead.
