One of the best known hydrothermal
area in the United States outside of Yellowstone.
The trail is easy, but the
elevation may leave you short of breath.
The mountain scenery is
excellent, and there are fine old Mountain Hemlocks along
Bumpass Hell stinks, and
bubbles, and steams, and is very cool. Probably not a
good place to be if the Lassen volcano re-activates, but
until then it makes for an excellent hike.
