Boulder Lake Peak is just shy of being a member of Idaho’s highest 100 peaks ranked at number 103. It is a seldom climbed summit because of it’s remote location and climbing difficulty which is Class 4.

South Ridge (Class 4)

Follow the Boulder Lake Trail (FST-057 (C)(1)(a)(p. 259) to Boulder Lake. Circumnavigate the lake on its west shore and ascend the eyebrow cliffs from their west side. From here, ascend to the east on steep talus towards Point 11,024, eventually bearing north past this point on the west. Cross ribs to reach ledges and short gullies that lead to the knife edge ridge below the summit.

George Reinier and Pat McGrane reached the summit on August 21, 2008 with no sign of prior ascent.
