Open Space Preserves

Due to the amount of tree debris and landslides, Foothills Nature Preserve is partially re-opened. Staff are actively working to clear debris to make the preserve's trails and roads safe for visitors. Please check this partial re-opening map and check the Foothills Nature Preserve webpage for updates.

Pearson- Arastradero Preserve is also partially open. Please check this partial re-opening map and check the Pearson-Arastradero Preserve webpage for updates.

The mission of Open Space is to protect and interpret the resources and wildlife entrusted to Palo Alto for the enjoyment of future generations.  The preserves offer trails from the marshes of the bay to the redwoods of the Santa Cruz mountains.


Baylands Preserve

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.

Esther Clark Nature Preserve

Esther Clark Nature Preserve is a good place for quiet meditation or watching the sunset. 

Foothills Nature Preserve

Foothills Nature Preserve 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 all guests.

Pearson - Arastradero Preserve

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.
