The Armstrong Woods Trailhead in Armstrong Redwoods State Natural Reserve provides access to a compact but demanding network of trails set within the redwood grove and surrounding hillsides. While the trails are well maintained and highly scenic, routes from this location involve sustained climbing and significant elevation gain. Even shorter loops are vertically dense, with limited flat running. The reserve connects easily to adjacent open space, allowing for longer routes without excessive repetition.
