Bumpass Hell Trail and Boardwalk Closed in 2018 for Rehabilitation

More information on specific closure locations is coming soon. We recommend visitors plan to visit another of the park's many hydrothermal areas this summer due to limitations in access necessary to ensure visitor and staff safety.

A Multi-Year Project

In 2018, the NPS will begin a multi-year project to rehabilitate the Bumpass Hell Trail and boardwalk. The purpose of project is to ease maintenance for the Bumpass Hell Trail and boardwalk, while preserving natural and historic resources, improving interpretive opportunities, and accommodating high visitor use to and within the Bumpass Hell Basin.

The hottest and most vigorous hydrothermal features in Lassen Volcanic National Park are at Bumpass Hell. A three-mile round-trip trail―one of the most popular in the park―provides access to the Bumpass Hell basin. Within the basin, a boardwalk traverses a portion of the hydrothermal area and additional trails offer access to the southern portion of the basin and connect to additional area trails. While Bumpass Hell is a popular destination for park visitors, it is also a dynamic geologic area in which the only predictable element is change.
 

Draft Environmental Assessment with Alternatives for Rehabilitation

An Environmental Assessment (EA) is being prepared by the National Park Service (NPS) for rehabilitation of the Bumpass Hell Trail and boardwalk. The alternatives have been vetted with the public and three have been selected for analysis in the EA:

1. No Action: Continue with current management
2. Expand Opportunities for Visitor Use
3. Improve Visitor Use

The EA will be posted for a 30-day public comment period in February 2018. The Finding of No Significant Impact (FONSI) will be signed shortly afterward.

Learn more with the alternatives description document (35 KB, doc), alternatives matrix (26 KB, doc), or alternative maps.
