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.

Comment on Alternatives for Trail and Boardwalk Rehabilitation through April 7, 2018

The NPS encourages your review and comment on the environmental assessment for the rehabilitation of the Bumpass Hell Trail and boardwalk. The final Environmental Assessment includes three alternatives. A summary is available in the Alternative Comparison Chart on pages 16-19.
