5★ Peru, Punta Olimpica 2017-09-25

The approach to this pass was spectacular up a steep paved road, with multiple switchbacks and glaciers hanging from the mountains. The ultimate summit was undercut by a tunnel but the old road to the original pass remained. We camped at 4670m altitude above the tunnel, and overlooking a stunning turquoise glacial lake. In the morning we attempted the original pass but were blocked by rock falls, and so reverted to the tunnel. map
