Route and access notes

A remote high-elevation wilderness trail from Crescent Meadow across the Great Western Divide to its junction with the John Muir Trail above Kern Canyon.

Planning this route

The refreshed connected geometry is 77.4 km, matching the National Park Service's 49-mile High Sierra Trail to the John Muir Trail junction. The optional continuation on the JMT to Mount Whitney is not included in this page.

Access and source limitations

An overnight wilderness permit is required. NPS currently reports downed trees and a washout between Mehrten Creek and Bearpaw, and stock restrictions at Chagoopa and Guyot Flat; high water, snow, fire and altitude hazards remain possible.
