The San Marcos Historical Society and hundreds of volunteers have spent countless hours restoring the Cox and Bidwell houseses to make them available to the public. Docent led tours provide a short history of the Twin Oaks Valley area of San Marcos, an introduction to some of the past homeowners, and what their life in San Marcos would between 1890 and 1930. The houses provide a glimpse of the past for visitors of all ages.
