National Historic Site of the United States
The John Muir National Historic Site is located in the San Francisco Bay Area, in Martinez, Contra Costa County, California. It preserves the 14-room Italianate Victorian mansion where the naturalist and writer John Muir lived, as well as a nearby 325-acre tract of native oak woodlands and grasslands historically owned by the Muir family. The main site is on the edge of town, in the shadow of State Route 4, also known as the "John Muir Parkway."
John Muir’s life was a tapestry of roles—fruit rancher, family man, writer—each interwoven with his deep love for nature. As one of America’s most influential naturalists, Muir was more than just an observer of the wilderness; he was its fiercest advocate. His passion for the land drove him to protect the places he held dear, ensuring that future generations could experience their beauty.





The main park site and visitor center are open Tuesday through Saturday from 10:00 A.M. to 5:00 P.M. We are closed on Sunday and Monday.
