Open Space Preserves


Our Mission
To protect and interpret the resources and wildlife entrusted to Palo Alto for the enjoyment of future generations.


Palo Alto's open space preserves offer trails from the marshes of the bay to the redwoods of the Santa Cruz mountains. The Baylands Preserve has some of the last remaining salt marsh and mud flat habitats on the west coast. It offers excellent birding year round. Pearson-Arastradero Preserve is a beautiful mixture of rolling grassland and broadleaf evergreen forest. Each area of the preserve has something different: views of the bay, a quiet grassland stroll, or a snooze by the lake. Esther Clark Nature Preserve is a good place for quiet meditation or watching the sun set. Foothills Park is a 1,400-acre preserve with rugged chaparral, woodland, fields, and a lake. Hike on 15 miles of trail, have a picnic,  or enjoy spectacular views of the bay from Vista Hill. This park is open to Palo Alto residents and their accompanied guests only.


Open Space offers a variety of nature programs, hikes, camps, walks, and other activities in the preserves.  Activities and Programs

History of Waste and The Baylands

The area now known as the Palo Alto Baylands started as a waste disposal site in the early 20th century. Over time we learned how to better treat and dispose of our waste, and even convert some of it into useful energy. The landfills are now closed and being turned into additional parkland.
