The steep slopes in the Southwest Area of the park, near the Kohm Yah-mah-nee Visitor Center, are popular with experienced sledders. Be sure to choose a slope that is right for your group and the conditions. Sledding is the number one cause of visitor injury in the winter season. Each winter rangers treat and evacuate sledders with head and spine injuries, lacerations, and broken bones. Icy snow creates very fast sledding conditions and trees and rocks abound in this area. Eskimo Hill, located north of the park in Lassen National Forest, is also a popular sledding area.

Bring your own equipment and enjoy Lassen's vast winter wonderland. If you're new to snowshoeing, considering joining a free ranger-led snowshoe walk offered on weekends in the winter; snowshoes are provided for the program only. The Manzanita Lake Area and the snow-covered Park Highway Route offer gradual climbs with limited avalanche danger, however avalanche terrain exists at the upper end of the Manzanita Creek trail near Loomis Peak. Numerous routes out of the Southwest Area offer trails of greater difficulty, many with spectacular winter views. Most of the primary snowshoe routes in the southwest area pass through frequent avalanche terrain.
