Within Lassen Volcanic National Park, at a chilly 8,000 feet in elevation, is a phantasmagoric location known as Bumpass Hell.
Bumpass Hell is the park’s largest hydrothermal area, but to many visitors, it appears unnatural, like a scene created by the imagination. Just hiking to the location suggests this is an irregular place. First, the pungent odor of rotten eggs rudely greets the nose. Then the landscape changes appearance; friendly greens and browns retreat to display barren, mineral stained soils of tan, orange, and yellow. Finally, looking into the active basin the ground’s surface is reminiscent of another world, it is etched, pocked and corroded; ghostly apparitions of steam hiss into the air while numerous mudpots pop and gurgle, and aquamarine pools roll with superheated water. It is harsh looking and very beautiful.
A wooden boardwalk allows for more safe exploration of the area. Posted signs stress the importance of staying on designated paths for safety reasons. Bumpass Hell was named after an early visitor who severely burned his leg upon falling through the surface’s thin crust and into boiling water.
Upon leaving, the crude odor of Bumpass Hell diminishes with distance, but it haunts the nose for a long time afterward.
The hydrothermal area is accessible by two trails. The popular three-mile hike begins at the Bumpass Hell parking lot, on Hwy 89, and requires several hours for a round trip. The elevation gain is about 300 feet. Be prepared for a crowded parking area and a busy trail in the summer. If you seek a less explored route the trail leading from the Kings Creek trailhead is very rewarding. This five-mile trail passes through majestic forests, crosses gentle brooks, and meanders through an area of volcanic formations that are layered and twisted. Plan for a hike that covers roughly 800 feet of elevation gain. In the summer, look for retreated snow banks that are hidden in the woods just off the trail.
