Wilderness Permit Information

Mount San Jacinto State Park and Wilderness is located at a high altitude where the growing season is short. Plant life has little opportunity to recover from overuse from one season to the next, and unless we take the steps to protect these areas, they could be lost to us forever. To ensure the preservation of the natural environment and assure the visitor of a quality visitor experience, the Department of Parks and Recreation has instituted a Wilderness Permit System.

Everyone entering the Mount San Jacinto State Wilderness, both for the day and overnight camping, must have a permit in their possession. Groups are limited to 15 people, and juvenile groups must have at least one adult leader for each 14 juveniles. Dogs are not permitted in wilderness areas of the State Park System.

Day Use Wilderness Permits are free and available 24 hours at:

Park Headquarters in Idyllwild
Long Valley Ranger Station on the Palm Springs Aerial Tramway side

Wilderness Camping Permits are $5.00 per person and are available at:

Online application (must be printed and mailed): Wilderness Camping Permit

The San Bernardino National Forest has a similar permit system in effect for its federal wilderness area known as the San Jacinto Wilderness. Both the State Park and National Forest honor each other's DAY USE PERMITS; however, each agency has its own camping permit system that you must apply for separately. San Bernardino National Forest permits are issued at the San Jacinto Ranger District located at 54270 Pine Crest, Idyllwild, CA 92549, (909) 382-2921.

Winter Conditions

Winters are highly variable in Mount San Jacinto State Park. Wet winters can dump several feet of snow, while dry winters may only result in a few inches here and there. Regardless, always be prepared for snowy/icy conditions. Traction devices like microspikes or crampons are highly recommended if you plan to hike into the wilderness. For up-to-date trail conditions, call the Long Valley Ranger Station at (760) 327-0222.
