An 8.7-mile (14 km) hike beginning at 9,000 feet (2,743 m) above sea level which is relatively level the first 7 miles (11.3 km) becomes very steep the last mile (1.6 km) and ascends to Jackass Pass at 10,800 feet (3,290 m), crossing the continental divide. From there one must descend a steep half mile (800 m) to Lonesome Lake, which is one of four lakes in the cirque. Expect the trail to be busy in July and August as the cirque is the most popular hiking and climbing destination in the Wind River Range. Lonesome Lake was the first lake in the Wind River Range whose water was deemed unfit for consumption due to human waste and consequently, no camping is permitted within a quarter mile (400 m) of the lake.
