Hawthorns, a 78-acre historic estate named for a hedge once lining its boundary, is one of the last remaining islands of open space in residential Portola Valley. The property was generously gifted to Midpen in 2012 and is now part of our Windy Hill Preserve.
In 2021, Midpen is tentatively expecting to begin exploring the feasibility of introducing public access to the western area of the property, including the possibility of a small parking area and loop trail. Hawthorns' rolling grasslands, oak woodlands, evergreen forests and year-round flows in Los Trancos Creek support a diverse community of native plants and wildlife.
The property was originally developed in the late 1880s as a summer estate, and its historic buildings are the subject of a separate planning process. A Preliminary Use and Management Plan for Hawthorns was approved by Midpen's board of directors on May 23, 2012. For more information visit the Hawthorns Historical Complex page.
A planning and public engagement process for public access to Hawthorns is tentatively expected to begin in 2021. Sign up on the email list below to be kept informed.
Developing a new trail in the Hawthorns area of Windy Hill Open Space Preserve and opening it to public access is a project identified in Midpen's Vision Plan Portfolio #6, and is supported by voter-approved Midpen Measure AA funds.
