A magnificent redwood forest 2 miles north of Guerneville, the 805-acre Armstrong Redwoods State Reserve was saved from the saw by a 19th-century lumber magnate. Short interpretive trails lead into magical forests, with trees 30-stories high. Beyond lie 20 miles of backcountry trails, through oak woodlands, in adjoining Austin Creek State Recreation Area , one of Sonoma County’s last-remaining wilderness areas. Walk or cycle in for free; pay only to park.
