The first public open space in the Conejo Valley was acquired in 1966, in a portion of what is now called Wildwood Regional Park. This led to a goal of conserving a ring of open space in the hills and mountains that surround the Conejo Valley.
Since that time, approximately 15,000 acres of open space have been preserved, accounting for approximately 39% of the city of Thousand Oaks planning area. The City's General Plan envisions that nearly 16,000 acres or 41% of the City's planning area will be open space at build out.
140 miles of multi-use trails have been built in open space. The area has been designated a "Trail City USA" by the American Hiking Society because of this extensive trail system.
The Conejo Multi-use Trails are trails shared by hikers, mountain bikers and equestrians. Dogs are permitted on leash. No motorized vehicles are permitted on open space trails.
Conejo Open Space Conservation Agency (COSCA)
In 1977 The City of Thousand Oaks and The Conejo Recreation and Park District (CRPD) created the Conejo Open Space Conservation Agency (COSCA) through a joint powers authority.
The primary responsibility of COSCA is to hold and manage most of the Conejo open space and to preserve its natural characteristics while providing opportunities for passive recreational enjoyment of the natural resources.
COSCA is governed by a 5-person Board of Directors consisting of two City Council members, two CRPD elected Directors, and one public member.

Conjeo Open Space Trails Advisory Committee (COSTAC)
Formed in 1988, the eleven member committee is composed of hikers, mountain bikers and equestrians who are appointed by the COSCA Board for a three-year term.
COSTAC acts in an advisory capacity to the COSCA Board, reviews issues and makes recommendations to the COSCA Board regarding open space and trails.
COSTAC also coordinates the COSCA Volunteer Corps, which is responsible for several open space programs including Trail Watch, Trail Patrol, Trail Work, Adopt-a-Trail, Non-Native Plant Removal/Resource Management, Trails Education Days, and Public Outreach.
Conejo Open Space Foundation (COSF)
Established in 1995 as a nonprofit corporation for public and charitable purposes. The primary responsibilities are to raise funds to promote and maintain multi-use trail and open space systems, and to educate the public, especially children, about our open space and the environment.
COSF supports the above COSTAC programs financially and provides funding to create and publish open space trail maps.
