Welcome to Lexington Reservoir County Park. This beautiful and scenic 950 acre park and reservoir is just minutes from the urban centers of Santa Clara County. The park includes the 338 acre man-made reservoir available for shoreline fishing. The County park is also part of a chain of parks and open spaces connected by the Bay Area Ridge Trail, which, when completed, will connect Sanborn with Almaden Quicksilver County Parks as well as Sierra Azul Open Space Preserve and other parks in the greater San Francisco Bay region.
