About Bumpass Hot Springs

Bumpass Hot Springs offers a raw, natural experience amid the rugged landscape of Lassen Volcanic National Park in California. This warm spring features bubbling pools formed by geothermal activity, surrounded by steaming fumaroles and striking volcanic terrain that connects you directly with the earth’s fiery heart.

Getting There

You reach Bumpass Hot Springs via an approximately 3.5-mile moderate hike from the parking area along a well-marked trail. The path winds through forest and meadows, so bring sturdy shoes and be prepared for some elevation changes. Parking is available but fills early on busy days, so an early start helps.

What to Expect

The spring pools vary in temperature, offering soothing warmth but occasional cooler spots where fresh mountain water mixes in. The surroundings feel wild and dynamic with steam rising from rock cracks, creating a sensorial outdoor hot tub. Crowds can build on weekends and holidays, but the space remains spacious enough to find a quiet corner. Facilities are minimal—there are no developed restrooms or changing areas nearby.

Tips for Visitors

Visit during weekday mornings or shoulder seasons to avoid crowds and enjoy a more tranquil soak. Bring water, snacks, and layered clothing as temperatures fluctuate after soaking. Remember there is a small entrance fee for Lassen Volcanic National Park. Respect the delicate environment: keep to trails and pack out all trash to preserve this active volcanic area.
