National Historic Site · CA
Information · Martinez Adobe
The Martinez Adobe, located on the western edge of John Muir’s historic orchard, is currently closed due to structural damage. It is unknown when the public will be able to enter the structure. The Muir/Strentzel mansion remains open to visitors.

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.
