More than 15,000 acres are designated as permanent open space in the Ventura County section of the Conejo Valley. 150 miles of trails weave through the open space, providing wonderful opportunities for open space enthusiasts to enjoy nature.

Volunteer

The COSCA Volunteer Corps has many ways for you to help maintain and preserve the open space that surrounds our beautiful Conejo Valley. By joining with other residents, you can insure that the trails, canyons, and ridges will remain in good condition for future generations.
