NPS Sites of the East Bay Area - part 2 -John Muir NHS
John Muir NHS in Martinez, CA is the site of John Muir's home and orchard. The small visitor's center has a movie about his life and you can wander through the house at your own pace, all the way up to attic and the cupola.
The grounds have fruit trees and it's an easy walk to the Martinez Adobe which Muir's daughter Wanda lived in and now houses a display on the Juan Bautista de Anza National Historic Trail. I was happy to find this display and learn something about it, as I had seen a number of the trail signs along the road.
