Siskiyou County

Siskiyou County sits in northern California between the Cascade Range and the Sierra Nevada. The landscape includes coniferous forests, rivers, and mountains that cover a large area.

The administrative unit was created in 1852 from parts of two neighboring territories during the Gold Rush era. A year earlier, a gold strike in Yreka had drawn thousands of people to the region.

The land preserves Native American heritage sites and incorporates the Klamath National Forest, offering extensive outdoor activities and seasonal celebrations throughout the year.

Interstate 5 runs north to south through the territory and connects towns such as Yreka, Mount Shasta, and Dunsmuir. Lodging ranges from hotels in the towns to campgrounds in the forested areas.

Mount Shasta rises as a freestanding volcanic mountain within the borders and reaches over 14,000 feet (4,267 m). Its summit remains snow-covered year-round and defines the skyline of the entire region.
