Here you will find the most recent trail conditions available. Be prepared for rapidly changing conditions. Thunderstorms are common during the summer months and can turn a clear day into a threatening situation in a matter of hours. Consider all possibilities before you head out on your trip and check out the Trail Safety page for more information on the dangers of wilderness travel.
At the end of September wilderness rangers are removed from the field and updated conditions become less available. You can help us by sending an email to report trail conditions. In general, you should expect winter conditions across the Parks' wilderness. For more information please call the Wilderness Office at (559) 565-3766.
For snowpack data, visit the California Department of Water Resources snow survey website.
Climbing Mt. Langley
During a project to restore the route to the top of Mount Langley, miles of social trails were removed and a new route was marked with cairns. If you climb Mount Langley, please leave the cairns in place and use them to follow the new route.
You may encounter "Drift Fences" in the wilderness. These fences are utilized to keep stock (horses, mules, and llamas) from roaming freely or impacting ecologically sensitive areas. Each fence has either a sliding pole or swinging gate across the trail for visitors to pass through. Please close all gates behind you to protect wilderness resources.
Major Rockfall on Whitney Portal Road
The road is currently gated just above Hogback Road on Whitney Portal Road to prevent vehicle entrance; however, foot traffic past the gate is not recommended due to the hazardous and potentially unstable conditions surrounding the rock fall. Find out more at https://www.fs.usda.gov/inyo/
