Hines Peak is a challenging summit of 6696 ft. To reach the summit is recommended as a multiday backpacking trip, or it can be done as a very long one-day trip. The knife-edge rock formation, close to the top, is the most difficult part of the trail, with very eroded terrain, so be sure to take extra caution at this part.
