The Conejo Canyons Open Space consists of 1,628 acres (659 ha) of open-space areas in northernmost Newbury Park, Ventura County, California.

[1] It consists of deeply eroded canyons, numerous ridgelines and plateaus in the northwestern portion of the Conejo Valley.

[8] These wetlands are connected to the Arroyo Conejo, which ultimately discharges into the Pacific Ocean by the Mugu Lagoon.

[9] The Conejo Canyons Bridge, which was opened in February 2012, established a connecting trail between the Arroyo Conejo Open Space and the Santa Rosa Valley and beyond to the Mount Clef Ridge of Wildwood Regional Park.

[10][11][12][13][14] The Conejo Canyons Open Space is operated and owned by the Conejo Open Space Conservation Agency (COSCA), and is used for mountain biking, hiking and horse-back riding.
