Bumpass Hell

Bumpass Hell is the largest discharge from the Lassen hydrothermal system. Water bubbles up from the ground and creates quite a spectacular multicolored view due to the minerals in the water. The start of the hike contains a few great overlooks into the mountainous Sierra Nevadas. Soon enough, you'll descend into the hydrothermal area, where you're required to stay on the boardwalks.

• Start at the Bumpass Hell Trailhead parking lot.
• Continue along the trail away from the road when you get to Lake Helen
• When you smell sulfur (the smell of rotten eggs), you'll know you're close
• Stay on the boardwalks and explore the region as your leisure
• When you're ready, retrace your steps back
