Open Space Preserves

Note: We welcome you to enjoy a walk in a park or an open space preserve while maintaining social distancing of more than 6 feet from persons outside of your household.  When letting others pass on trails, be aware of snakes, ticks, Poison Oak and your footing when making room off the trail. In order to help stop the spread of COVID-19 and protect the health of the public and staff, please follow the Santa Clara County Health Order.  

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.
