The 30-mile park highway connects the northwest (Manzanita Lake) and southwest entrances of the park. This scenic route passes through dense forest, traverses a ridge with views of Lake Almanor to the south, crests at 8,512 feet near Lassen Peak trailhead, and descends steep volcanic slopes into the southwest area. There are no guardrails on this route due to snow removal requirements. The southern section of the highway is windy and includes a handful of switchbacks. Designated turnouts and parking areas provide opportunities to enjoy the highway highlights.
