Panorama of Conejo Valley showing open space and trails

Conejo Open Space Conservation Agency


January 19, 2023 - COSCA Trails are now open!  Thank you for your patience and helping to protect our trail network during the unusually long series of atmospheric rivers the region encountered.  Repairs to some storm-damaged areas may still be in progress, so please be mindful when passing through these areas.  Updated closure info is also available Here.

Buying an E-Bike this Season?
E-bikes are increasingly popular, but not all of them are permitted on all trails. If you're shopping for one this season, make sure it's allowed where you want to ride. Check out this handy Buyers Guide from our friends at Trails are Common Ground and IMBA, and find COSCA e-bike info HERE.

Leave No Trace Guidelines
Keeping our community open spaces clean, healthy, safe, and enjoyable takes a community-wide effort. By following a few simple guidelines, you can be part of COSCA's open space care team. For tips on outdoor ethics, see our Leave No Trace page.
