Description

One of the fastest ways to get above treeline in the Sierra. In just 7 miles you climb from South Lake to Bishop Pass (11,972ft) and drop into Dusy Basin: a sprawling granite playground of tarns, slabs, and massive peaks. This is a weekend trip that delivers scenery most people spend a week hiking the JMT to reach.
