Offering excellent views of the east side of Lassen Peak, this easy walk introduces visitors to effects of the Lassen Peak eruptions. A short ways in, the trail forks and can be followed in either direction. Wandering through pink and gray lava rocks, interpretive plaques along the trail describe the creation of the devastated area and the remnants it left behind. This short, informative trail is an excellent choice for families or those unable to take longer trails.

The Devastated Area parking area is located on the park road 19.1 miles from the southwest entrance or 9.7 miles from the northwest entrance. The marked trailhead begins in front of the restrooms on the east side of the parking area.
