Less than three hours from San Francisco in the heart of the Anderson Valley wine region, Hendy Woods State Park protects two groves of towering redwoods. Some of its trees may be more than 300 feet tall and 1,000 years old. Five miles of trails, including Big Hendy Grove’s wheelchair-accessible Discovery Trail, lead through the fern-filled forest. Warmer and less foggy than most redwood parks along the coast, Hendy Woods is a popular spot for swimming in the summer and canoeing and kayaking in late winter and early spring. The park is also known for the Hendy Hermit, a Russian immigrant who lived near the park for 18 years.
