Ishi Wilderness

Ishi Wilderness is a large protected area in the Sierra foothills featuring steep canyons, rocky outcrops, and basalt formations. The terrain varies significantly in elevation, creating diverse environments with different vegetation and wildlife across the landscape.

The Yahi-Yana people lived here for thousands of years until displacement began in the 1800s. It became an official protected area in 1984 through legislation meant to preserve the landscape and its cultural heritage.

The name honors Ishi, the last member of the Yahi tribe who emerged from isolation in 1911. Walking through the area, you can find traces of Native American settlements and sacred sites scattered across the canyons.

The area has hiking trails through forests and along streams where visitors can explore on foot. Spring and fall offer the most comfortable conditions, with moderate temperatures and good trail accessibility.

The wilderness hosts California's largest population of migratory deer that moves through the canyons each year. The streams also support salmon and trout, making it an important habitat for fish species and wildlife watching.
