Bumpass Hell Trail

The trailhead for the Bumpass Hell Trail is located in Lassen Volcanic National Park. Parking is available at the trailhead, but it can fill up quickly, especially during peak season. Arriving early in the morning is highly recommended to secure a spot.

Due to significant snowpack at its high elevation, the trail is typically only open in late summer and fall, often opening around the Fourth of July weekend. Always check current trail conditions before planning your visit, as snow can linger into early summer.

The trail is considered easy to moderate. The first mile is mostly flat with a hard-packed dirt and rock surface. However, the last half-mile descends about 300 feet into the basin, involving some rocky steps and steeper slopes. The high elevation (8,160 to 8,400 feet) can also make the hike more challenging due to thinner air. Good hiking shoes are recommended.

You'll experience diverse scenery, including panoramic views of Little Hot Springs Valley and volcanic peaks like the five remnant peaks of the ancestral Brokeoff Volcano. Highlights include the Brokeoff Volcano Vista, a View of Crumbaugh Lake, and Cold Boiling Lake. The main attraction is the Bumpass Hell basin itself, with its vibrant hydrothermal features, including fumaroles, hot springs, and bubbling mud pots, accessed via a boardwalk.

No, dogs are generally not permitted on trails within Lassen Volcanic National Park, including the Bumpass Hell Trail. This is to protect both the park's wildlife and your pet's safety. Service animals are an exception.

While a specific permit for the Bumpass Hell Trail is not required, you will need to pay an entrance fee to enter Lassen Volcanic National Park. This fee covers access to the park for a set number of days. Check the official NPS website for current fee information.

The hike is approximately 3 miles round trip and generally takes about 1 to 3 hours to complete, depending on your pace and how much time you spend exploring the geothermal basin.

The trail is famously named after Kendall Bumpass, an early settler who, in the 1860s, discovered the area by inadvertently stepping through a thin crust into a boiling mud pot. He severely scalded his leg, which later had to be amputated, and reportedly called the place "Hell," leading to its memorable name.

Yes, safety is crucial. Always stay on marked trails and boardwalks within the Bumpass Hell basin, as the ground can be a thin crust hiding acidic boiling water and mud. The strong sulfur smell is normal, but be aware of the high temperatures of the thermal features. Also, be prepared for high elevation conditions, including thinner air and potential for lingering snow.

The Bumpass Hell Trail is generally considered accessible to a wide range of ages and abilities, making it suitable for families. However, the descent into the basin has some steeper sections, and the high elevation can be a factor. Always supervise children closely, especially around the geothermal features, and ensure everyone stays on the boardwalks.

Given the high elevation and varied terrain, it's advisable to pack plenty of water, snacks, sun protection (hat, sunscreen), and layers of clothing as temperatures can change. Sturdy hiking shoes are a must, and trekking poles can be helpful for the steeper sections. Don't forget a camera for the incredible scenery!
