Overview

The Lassen Peak trail is a strenuous but rewarding hike that culminates at the summit of Lassen Peak, the southernmost active volcano in the Cascade Range. The trail, a 4.8-mile round trip with 1,957 feet of elevation gain, is a test of endurance and determination. Most of the way, the trail is steep with about a 15% grade, typically taking 4-6 hours to complete. The trailhead is located at the Lassen Peak parking area, about 6.75 miles north of the southwest entrance of Lassen Volcanic National Park off the main park road. Points of interest you will pass include: Sulphur Works, Bumpass Hell, Helen Lake, and Emerald Lake.

The trail is well-maintained with switchbacks and is easy to follow. This high-altitude hike starts at 8,500 feet and reaches the highest point in the park at 10,457 feet. The steep grade and high elevation can aggravate pre-existing medical conditions.

Trail Conditions

The trail is generally open from July to October, depending on snow conditions. However, it can be icy and snowy early and late in the season, so hikers should be prepared for winter conditions. The trail is exposed to the sun and wind for most of the hike, so hikers should bring sunscreen, hats, layers, and plenty of water.

Highlights of Hiking Lassen Peak

The views from the summit of Lassen Peak are spectacular, offering panoramic vistas of the surrounding mountains, forests, and valleys. The trail passes through a variety of volcanic features, including lava flows, cinder cones, and fumaroles. Hikers may also see wildlife, such as marmots, pikas, and deer.  You can see Mt. Shasta, about 80 miles to the north, from the top of the trail.  Prospect Peak is in the northwest corner of Lassen Park, and many of the lakes in the park, and Lake Almanor to the southwest, can be seen.

Take your time hiking to rest and enjoy the views and vistas on the Lassen Peak Trail.

A highlight for many is experiencing the California Tortoise Shell Butterflies when they are migrating in the summer months.
