Lassen Peak is only one of two active volcanoes in the contiguous United States, the other being Mount Saint Helens (8,364 ft.). Prior to 1914, it seemed to be a volcanic plug, and was believed to be extinct. In 1914, it erupted for the first time in what would be a series of 150 eruptions over the next three years. Its violent fit of eruptions ceased in 1917, but Lassen is still considered active.

Lassen is the southernmost volcano in the Cascade range, located in Lassen Volcanic National Park. The park holds several volcanic peaks, including Cinder Cone (6,913), Prospect peak (8,342 feet) and Mount Harkness (8,039 feet), plus several smaller peaks and great lava fields, hot springs, hot lakes, and mud volcanoes, all connected with an excellent network of hiking trails. All of the cones, including Lassen, are easily climbed.

    On a previous trip to Lassen Volcanic National Park a hike to the peak was not possible. I then planned a second trip to the park with the intention of hiking to the top. The one way distance of 2.5...

    Lots of people--easy trail. Lots of switchbacks. You pretty much can drive to the base and climb in an afternoon. Nice view from the top

    3 hrs with my almost-6-years-old son. Summit in fog. He had a great time, and so did I.

    Should be easy but I did it on a badly sprained ankle. Took forever. Tourist trap.

    i would not go as far to say that this was a major hike. 3 miles is a simple walk. Try whitney or shasta.

    Got a late start (~5:30 pm), but it turned out to be the perfect time: the sunset was amazing! The hike up wasn't too bad (for being a rookie), and the trip down only took 30 minutes or so. I felt...

    My first mountain ever, I think I'm hooked... Warm weather at the base, but cooled off quickly during the ascent. Started out late and saw the sunset at the summit, absolutly astounding. If I could...

    I had 2 summits but many partial ascents (lived nearby). Snow storms and lightening happen fast. It can be a hot day, but freezing on the snow at the summit. Go on a sunny day to see Shasta and Mt...

    WOW! It doesn't seem to accurately describe the view from the top. The hike was a challenge but well worth the view of the valley, surrounding park and Shasta from the top. The trail was clear of...

    We snowshoed from the Ski chalet up the road to the mountain. We then climbed straight up the ridge with the normal summer trail. We took two and a half days. It was a great winter mountaineering...

    In addition to the usual path, there are some interesting simple snow climbing possibilities on the northeast side of the mountain, above the Devastated Area. I'm a little wary of rockfall on the big...

    A straightforward hike with terrific views. This peak would be a great introduction to the Cascade volcanoes for those who have never climbed.

    Climbed Mt. Lassen in 1992 and 1995, both times by the summit trail from the Lassen Park Road. Gorgeous weather both times, but also windier than hell. Nice view north to Shasta.
