San Jacinto Wilderness

Unique among designated areas, the San Jacinto Wilderness lies split in half by Mount San Jacinto State Park and its wilderness area, which is managed by the California Department of Parks and Recreation. The boundaries embrace the grand San Jacinto Mountains (elevations from 6,000 feet to 10,000 feet), and the flora and fauna varies from desert to alpine.

Steep cliffs and ridges descend dramatically from pine-covered peaks in the northern half of the wilderness. In the central section, high mountain plateaus shelter lush, stream-splashed meadows surrounded by magnificent forests. In the south, a section known as the Desert Divide lies densely covered with stands of chaparral. On this divide's eastern flank, you'll find several deep, eroded, boulder-strewn desert canyons.


A free permit is required for day hiking and overnight trips within the federal wilderness area. Please see information below about how permits work for long-distance PCT hikers or when crossing into the state wilderness area managed by Mt. San Jacinto State Park.

Keep yourself safe on the trails while protecting your vehicle and valuables back at the trailhead with the following tips:

  • General Hiking Tips: Trails in the federal and state San Jacinto Wilderness areas are recommended for the intermediate to expert hiker. Elevations range from approximately 6,400 ft. at the Devils Slide Trailhead to 10,804 ft. at San Jacinto Peak. Please review the Forest Service's hiking safety tips before heading out on your trip.
  • Winter Hiking: Dangerous conditions exist when snow and ice conditions are present. This is especially dangerous on portions of trails that are exposed to steep terrain, such as the Pacific Crest (PCT), Devils Slide and South Ridge trails. Visitors should take extreme caution and only go with proper gear (e.g. traction devices, ice axe, etc.) and experience/training using that gear.
  • Protect Your Vehicle: You'll be away from your vehicle for a few hours to a few days. Help protect your vehicle and valuables by reading the Protect Your Car section on the Forest Service's crime prevention webpage.
