Austin Creek State Recreation Area
🌲 6,000 Acres of Backcountry Wilderness Above the Redwoods — Sonoma County’s Wild Heart — Austin Creek State Recreation Area in Sonoma County, California, 6,000 acres of rugged backcountry adjacent to Armstrong Redwoods, 20 miles of hiking trails, Gilliam Creek Trail, oak woodlands and chaparral, elevations 150–1,500 feet, primitive backcountry camping, wildlife habitat, Russian River gateway — Sonoma County, CA
Most visitors to Armstrong Redwoods never leave the cathedral grove. They walk among the ancient coast redwoods — some over 1,400 years old — and drive home. They never see what’s above.
Austin Creek State Recreation Area is the 6,000-acre wilderness that rises above the redwood groves. A steep, narrow mountain road climbs from the forest floor into a different world — open oak woodlands, sun-baked chaparral, grassy ridges, and deep creek canyons where the only sounds are water, wind, and birdsong. This is Sonoma County’s backcountry, and it is almost entirely empty.
What to See & Do
| Feature | Details |
|---|---|
| Gilliam Creek Trail | The signature trail — moderate to strenuous, descending into a forested canyon along Gilliam Creek. Shaded oak woodlands, wildflowers in spring. Can be seasonally impassable at creek crossings during winter rains |
| 20 Miles of Trails | A network of interconnected trails through varied terrain. Significant elevation changes (150–1,500 feet). From ridgeline views to creek-bottom forest |
| Wildlife | Black-tailed deer, wild turkey, bobcat, coyote, and a rich diversity of raptors and songbirds. The transition zones between forest and grassland create exceptional habitat |
| Armstrong Redwoods Access | The park shares its entrance with Armstrong Redwoods State Natural Reserve — home to old-growth coast redwoods including the 1,400-year-old Colonel Armstrong Tree |
| Backcountry Solitude | While Armstrong Redwoods can be crowded, Austin Creek is almost always empty. This is true backcountry solitude 90 minutes from San Francisco |
