NPS

For John Muir, Mt. Wanda and the surrounding hills were common hiking spots and a place where he passed his love of nature to his daughters.

“Another lovely day, mostly solid sunshine. Took a fine fragrant walk up the West Hills with Wanda and Helen, who I am glad to see love walking, flowers, trees, and every bird and beast and creeping thing.” --John Muir, April 12th, 1895, Alhambra Valley, Contra Costa County, California. As cited in John of the Mountains: the Unpublished Journals of John Muir by Linnie Marsh Wolf

The natural landscapes that Muir and his daughters explored in Martinez can be experienced by all at the John Muir National Historic Site. The park works to protect these landscapes and provide present and future generations with the opportunity to enjoy them.

Mt. Wanda stands at about 650 feet and consists of over 325 acres of natural open space and hiking trails. It features the iconic and diverse natural habitats commonly found in the east San Francisco Bay Area.
