Foothills Park

Boronda Lake at Foothills Park


Bounded by Portola Valley, Los Altos Hills, Pearson-Arastradero Preserve and Los Trancos Open Space Preserve, the 1,400-acre Foothills Park is a nature lover's paradise. Miles of trails provide access through rugged chaparral, woodlands, fields, streams, and a lake, and provide spectacular views of the Bay Area. Wildlife abounds, and it is common to see deer and coyotes; if you are lucky you might catch a glimpse of a bobcat.

The land for Foothills Park was sold to the City of Palo Alto by Dr. Russel Lee, founder of the Palo Alto Medical Clinic, and his wife Dorothy in 1958, on the condition that it be preserved as open space. The park was formally dedicated in 1965. The Interpretive Center in the park is housed in a building originally built by the Lees as a horse stable.
