Humboldt Bay Trail


The Humboldt Bay Trail is a network of paved paths connecting the communities around Humboldt Bay. Efforts are actively underway to complete a continuous 14-mile, non-motorized trail from central Arcata to the southern end of Eureka. This trail will increase road safety, provide a low-cost travel alternative, expand recreational opportunities, improve community livability, and promote active, healthy transportation. The trail is being constructed in phases by the cities of Eureka and Arcata and Humboldt County, with support from Caltrans, the North Coast Railroad Authority, California Coastal Conservancy, and many other entities. Construction funding is secured for all but the final four miles of the trail, a section called the “Humboldt Bay Trail South” Project, which extends from the Target store near Eureka Slough to the Bracut Industrial Park near Bayside Cutoff.

Humboldt County intends to adopt a mitigated negative declaration of environmental impact for the Humboldt Bay Trail South Project for compliance with the California Environmental Quality Act (CEQA). The public review period for the CEQA environmental document is February 16, 2018, through March 19, 2018. Comments can be submitted via e-mail to or mailed in hard-copy form to Humboldt County Department of Public Works, 1106 Second Street, Eureka, CA, 95501.

Partnerships For Trails

Three local agencies are currently leading the development of segments of the Humboldt Bay Trail:
  1. County of Humboldt
  2. City of Arcata
  3. City of Eureka

Humboldt County is leading the development of the Humboldt Bay Trail South segment which will provide the interconnecting link between Eureka’s and Arcata’s trail projects.

The County was allocated funds in 2015 through the State Transportation Improvement Program to complete preliminary engineering, environmental studies, and permitting and to develop engineering plans and specifications for the Bay Trail South project. Right-of-way, permits, wetland mitigation, and funding for construction still need to be secured. Preliminary cost estimates for construction range from $14 to $16 million. The goal is to have engineering plans, funding and permits in place to initiate construction by 2021.

Humboldt Bay Trail: Travel and Trail Use Survey

The County of Humboldt is pursuing the funding necessary to construct the final four miles of the Humboldt Bay Trail between Eureka and Arcata.

Do you currently use the Humboldt Bay Trail to commute to work, to run errands, or just for fun? Would you be more likely to use the trail if it connected Eureka and Arcata? The County of Humboldt would like to know how a completed Humboldt Bay Trail would impact you and your family.

Please complete a survey at to share your experience.

The results from this survey will be used to help potential funders understand the benefits this project could bring to communities around the Humboldt Bay – your input is much appreciated.

Humboldt Bay Trail South Public Meeting

Completing the Humboldt Bay Trail between Eureka and Arcata


Meeting Presentation

Comment Form – general comments

Comment Form – CEQA environmental document

The County of Humboldt sponsored a public meeting to discuss the plan to complete the Humboldt Bay Trail between Eureka and Arcata. The meeting began with an informal open house to view exhibits of the current design and talk with planners and engineers, followed by a project update presentation and question-and-comment session. Approximately 135 people attended.

Please see News Flash for more information about this meeting. 

The Humboldt Bay Trail Fund

The Humboldt Bay Trail Fund was established at the Humboldt Area Foundation to provide a mechanism for private donors to assist in the continued development of the Humboldt Bay Trail by focusing on the critical need for trail maintenance funds. The fund will give priority to on-going emergency trail maintenance with emphasis on supporting volunteer efforts. Make an online donation!
