This is a trail to Lassen Peak during winter months when the park road is closed. The trail begins from the Southwest entrance of Lassen National Park. It follows the windy park road, with some cross-country trek, as it weaves between scattered pine trees and past Sulphur Works, an active geothermal area where steam puffs out of the ground. The road ends at the base of Lassen Peak and makes several tight switchbacks as it makes a steep ascent to the summit. There are several amazing views from beginning to end of rocky jagged peaks and valleys all covered in snow. This trip is generally done as an overnight. Lassen Peak is exposed with slope degrees ideal for avalanches. High winds and avalanches are common, check with the park for weather conditions. The park road is generally open to vehicles in April when plowing begins, again, check with the park for open and closure dates of the road as they are dependent on snowfall. Restrooms are available at the parking lot.
