Jack London State Historic Park spans over 1,400 acres in the Sonoma Valley, preserving the former estate of the American author. The site contains the ruins of Wolf House, a 15,000-square-foot mansion destroyed by fire in 1913 before London could inhabit it. Visitors can view the author's gravesite, marked by a moss-covered volcanic boulder. The House of Happy Walls museum, built by London's wife Charmian, serves as a visitor center showcasing the couple's personal artifacts and literary collection. A network of over 20 miles of trails traverses redwood forests, oak woodlands, and open grasslands. The property maintains the original cottage where London wrote several of his works, including 'John Barleycorn'. Historic agricultural infrastructure, such as the stone winery buildings, remains visible on the grounds. The site functions as a non-profit operated park under a partnership with California State Parks.
