Great Redwood
Trail Agency

The Great Redwood Trail Agency (GRTA) is a local agency established to develop and manage the Great Redwood Trail in Humboldt, Mendocino and Trinity counties.

Great Redwood Trail Agency

The GRTA was established in 2021. The GRTA’s service area is the former North Coast Railroad Authority (NCRA) rail corridor in Mendocino, Trinity, and Humboldt Counties. The rail corridor in Sonoma and Marin Counties was transferred to Sonoma – Marin Area Rail Transit (SMART). The Great Redwood Trail is a 307-mile, world-class, multi-use

rail-to-trail project connecting California’s San Francisco and Humboldt Bays. The legacy trail will travel through some of the most remote and scenic landscapes in the United States, traversing old growth redwood forests, running alongside oak woodlands and vineyards, and winding through the magnificent Eel River Canyon.
