Anderson Marsh State Historic Park contains 1,065 acres of oak woodland, grass-covered hills, and tule marsh. One of the largest groups of people in prehistoric California, the Southeastern Pomo, knew this land as home. Today, descendants of the Pomo still live nearby.
Anderson Marsh's archaeological sites hold clues to the lives of the Pomo. Some sites are over 10,000 years old, making them among the oldest in California. The park protects several habitats including freshwater marsh, oak woodland, grasslands, and riparian woodland.
If you like to hike, you can take advantage of miles of trails. Trailside signs offer insight into the native plants and animals of the park. The park is also popular for bird-watching, hiking and picnicking. Explore the past at the historic Anderson Ranch, with its nineteenth century structures. The park has a popular Bluegrass festival the 2nd weekend in September.
The park is located on the southeast corner of Clear Lake, the largest natural lake completely within the borders of California. Between Lower Lake and Clear Lake on Highway 53, north of Calistoga in the wine country.
