Wilderness Profile


Just three miles off of Interstate 80, Castle Peak Potential Wilderness is among the most scenic areas in the Tahoe National Forest. Home to extraordinary old-growth red fir forests and the little Truckee River, Castle Peak provides clean drinking water to residents of Nevada County.

Ishi Potential Wilderness Additions

Managing agency: Lassen National Forest.

Size: Approximately 48,000 acres.

Location: Extends from ten miles south of Lassen Volcanic National Park to five miles north of Cohasset in Tehama County.

Description:

  • Maintains threatened populations of salmon and steelhead trout.
  • Features the Mill Creek National Recreation and Antelope Creek Trails.

The area is dominated by deep canyons lined with lava rimrock and pinnacles. The upper elevations support ancient forests of ponderosa pine and Douglas fir that provide habitat for several old-growth dependant wildlife species such as the California spotted owl and pine marten. The lower-elevations support oak woodlands, chaparral, and grasslands—a rare landscape in the wilderness system. Deer, Mill, and Antelope creeks are among the few remaining streams in the Sierra Nevada maintaining threatened populations of salmon and steelhead trout, as well as a large array of other native fish.


A portion of the Lassen Trail, an early pioneer route, also passes through the region. Several trails provide access into the area for hikers, anglers, hunters, and equestrians. The Mill Creek Trail is especially popular, and the Antelope Creek Trail is becoming known for its spectacular spring wildflower displays.

The region is rich in Native American culture, and is named in honor of Ishi, the last surviving member of the Yahi Tribe.
