The John Muir Trail: Planning Your Sierra Nevada Traverse
Permits, resupply, direction and timing for California's famous long trail from Yosemite Valley to Mount Whitney.
The John Muir Trail runs through the High Sierra from Yosemite Valley to the summit of Mount Whitney — at 4,421 m, the highest point in the contiguous United States. Along the way it crosses a series of high passes, granite basins and hundreds of lakes. Much of it overlaps the Pacific Crest Trail.
Permits
Permits are the biggest hurdle. Most hikers apply through the Yosemite wilderness permit lottery for a southbound start. Demand far exceeds supply, so apply for multiple dates and trailheads, and consider starting from an alternative trailhead outside Yosemite.
Direction
- Southbound (SOBO): The most popular direction. You start at lower elevation and acclimatise gradually, finishing on Whitney.
- Northbound (NOBO): Easier permits but a brutal start, with high elevation from day one.
Resupply
There are few road crossings, so resupply takes planning. Common options include Tuolumne Meadows, Red’s Meadow, Vermilion Valley Resort and Muir Trail Ranch, where you can mail a bucket of food ahead. The longest stretch without an easy resupply can be 8–10 days of food.
Bear canisters
Approved bear-resistant food containers are required along the entire trail. They’re bulky, so plan your pack around one.
When to go
July to September is the main window. Early season means snow on the passes and high river crossings; late season brings cold nights and the chance of early storms.
