Bumpass Hell Trail is a 3-mile out-and-back foot trail in Lassen Volcanic National Park, California. Difficulty: moderate, estimated from distance. That is the full hike: the mapped trail line runs 6.38 mi because it also covers connecting trails, so it is not the length of this hike. The figure is for the Park Service's “Hike to Bumpass Hell” hike, which uses this trail.
