Volunteers invited to first Humboldt Bay Trail cleanup between Eureka, Arcata

Trash, brush and invasive plants were among the first maintenance issues targeted on the new Humboldt Bay Trail, where volunteers were invited to take part in the corridor’s first community cleanup between Eureka and Arcata.

The effort reflected how quickly the 4.3-mile paved segment has become more than a path. County materials describe the Humboldt Bay Trail as a network of multi-use routes for walking, running, biking and rolling, and the Eureka-to-Arcata connection, completed in 2025, now serves as one of the region’s most visible shared public spaces. That visibility is part of the reason early stewardship matters. A trail built for recreation, commuting and tourism can only stay welcoming if litter, overgrowth and other small problems are dealt with before they harden into bigger ones.

The cleanup centered on places where the trail meets the ground realities of a coastal corridor. At the Arcata end, volunteers met in the parking lot north of the City of Arcata Corporation Yard and worked to clear brush, remove invasive plants and pick up trash. A second cleanup was planned for the Eureka end at the Samoa Bridge boat launch parking lot. The work was modest in scale, but the message was larger: the new trail is already being treated as a public investment that needs care, not just construction.

County project materials say the Eureka-to-Arcata segment was built from 2023 through 2025 and includes three new bridges, major rehabilitation of the 750-foot Eureka Slough Bridge, shoreline repair, flood protection work and trail amenities such as map kiosks, interpretive signs, automatic trail counters, wayfinding signs and benches. The broader Humboldt Bay Trail vision is a continuous route of about 13 miles, linking into both the Great Redwood Trail and the California Coastal Trail. In that context, keeping the newest section clean and safe is about more than appearance. It helps protect a corridor that was designed to connect neighborhoods, support active transportation and strengthen the bayfront experience for residents and visitors alike.

Public Works Director Thomas K. Mattson has said the project was intended to restore shoreline access, protect the shoreline and provide a stand-alone paved route for people traveling by bicycle, skateboard, stroller, wheelchair and other mobility devices. A county planning study released in February 2026 identified the Eureka-to-College of the Redwoods connection as the next regional priority, a sign that the trail’s opening was not the finish line. It was the start of a larger effort to build and protect one of Humboldt County’s most important east-west links along the bay.
