Dos VientosOpen Space Trails

elcome to the Dos Vientos Open Space trail system. This large open space area consisting of 1,216 acres and 41 miles of shared use trails (hiking, cycling, equestrain) was originally part of the Rancho Guadalasca Spanish Land Grant of 1836. Dominated by chaparral and coastal

sage scrub habitats, this area provides a home for a wide variety of wildlife as well as rare and endangered plants including Conejo buckwheat, Verity’s dudleya, and Conejo dudleya. Mountain lions are known (although uncommon) inhabitants, as are coyote, mule deer, and bob cat. This area is also considered an important wildlife movement corridor into the Santa Monica Mountains National Recreation Area through Point Mugu State Park to the south.

The trail system provides internal and regional trail connections, as well as views of the Pacific Ocean and the Channel Islands. Directly to the south of Dos Vientos Open Space are Rancho Potrero (COSCA), Rancho Sierra Vista/Satwiwa (NPS), and Pt. Mugu State Park, including the Boney Wilderness (CA State Parks) encompassing over 16,000 acres of open space. The Los Robles Trail and Open Space system is located immediately to the east of the Dos Vientos trail system and provides connectivity to Westlake Village. The Dos Vientos trail system is managed by the Conejo Open Space Conservation Agency (COSCA), a joint powers authority created by the City of Thousand Oaks and the Conejo Recreation and Park District in 1977.

Open space and trails are open from sunrise to sunset except during inclement weather and emergency conditions when trails may be closed.
