High Sierra Backpacking Trail
What to Expect
Safety Advisory
Stream crossings can run fast and thigh-deep during snowmelt in June and early July — unbuckle your pack's hip belt before crossing and use trekking poles for stability.
Afternoon thunderstorms are common above treeline from July through September — plan to be off exposed ridges and passes by early afternoon, and know the signs of incoming lightning.
Bear canisters are required for all overnight trips — hanging food from trees does not work in the High Sierra, and rangers actively patrol for compliance.
Trail Details
- 1
Pick up your wilderness permit from the Mineral King or Roads End ranger station the day before your trip — quota permits for popular trailheads fill fast, and walk-up availability is a gamble after mid-July.
- 2
Carry a reliable water filter and plan your fills around mapped streams rather than lakes — moving water is more reliable in late season, and several of the higher lakes can dry to puddles by September.
- 3
Camp at the second lake basin rather than the first — most backpackers stop at the earliest flat spot, so pushing another two miles buys you a campsite with better wind protection and far fewer neighbors.
