Spanning 1.1 million acres across northeastern California, Lassen National Forest offers a rugged landscape shaped by volcanic activity and alpine terrain. Established in 1905 and named after pioneer Peter Lassen, this forest borders the Sierra Nevada to the south, the Modoc Plateau to the east, and California’s Central Valley to the west.
The forest’s proximity to Lassen Volcanic National Park makes it an ideal basecamp for exploring one of the most geothermally active regions in the country. Two large lakes anchor the recreation area, providing opportunities for fishing and water activities during summer months.
Hikers will find trails winding through mixed conifer forests, past volcanic formations, and along alpine ridges. The varied elevation—ranging from valley floors to mountain peaks—creates diverse ecosystems and stunning viewpoints throughout the forest.
Twenty-four campgrounds dot the landscape, including popular sites like Merrill Campground, Hat Creek, and Almanor near the lake. Gurnsey Creek and Christie Campground offer quieter alternatives for those seeking solitude.
The forest headquarters in Susanville serves as the gateway community, located approximately 80 miles east of Red Bluff via Highway 36. This accessibility makes weekend trips feasible from Sacramento and the Bay Area.
Peak season runs from late May through October, when roads are clear and campgrounds fully operational. Summer brings warm days perfect for hiking, while fall delivers golden aspens and fewer crowds. Winter transforms the higher elevations into a snow-covered backcountry, though many roads close seasonally.
