Master Plan Overview

The Great Redwood Trail Master Plan will be a roadmap for planning, constructing, and managing the future Great Redwood Trail. The master plan will be informed by a robust Community Engagement Plan that will capture community desires, concerns and ideas to develop the Great Redwood Trail. Once complete, the master plan will serve as a guiding document to address issues including but not limited to trail user experience, trail design, operations and maintenance, habitat restoration, project priorities, funding, and management of the trail. The master plan covers Mendocino, Trinity and Humboldt Counties. The Great Redwood Trail in Sonoma and Marin Counties will be planned and constructed by SMART. Share your vision for the Great Redwood Trail by participating in the surveys, events, and meetings listed below.

Vision for the Trail

The Great Redwood Trail (GRT) is envisioned as a 316-mile rail-to-trail project connecting California’s San Francisco and Humboldt Bays. What will be the longest of its kind, this multi-use trail will travel through some of the most 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. The GRT will connect the many vibrant communities of Humboldt, Trinity, Mendocino, Sonoma, and Marin Counties, creating a transformational economic engine and boosting healthy recreation for all in the North Coast region.
