10/07/2024 - Annual Fall Trail Work Day!
Come join the COSCA Rangers for our annual Fall Trail Workday at the Wishbone Trail. We will be heading up the west side of Wishbone grubbing out summer mustard, removing slough, tuning up the back slope and cutting back the bush mallow that’s encroaching the trail. All hand tools will be provided as well as gloves. No experience is required. Cold drinks and small snacks will be available as well as a taco truck lunch courtesy of the Conejo Open Space Foundation. Please bring sunscreen, water, a hat, and closed toed shoes. This event is subject to cancellation based on weather conditions. Meet up at the parking lot for the Westlake YMCA off Thousand Oaks Blvd., and please register in advance at www.cosf.org/register/. Thank you!
08/13/2024 - Trail and Parking Lot Closure!
COSCA’s trailhead parking lot in Hill Canyon and an approximately 1-mile section of the Canyon Overlook Trail will be closed from Monday, Aug. 19 to about the end of October to allow Southern California Gas to perform important infrastructure maintenance work. Please avoid use of the Canyon Overlook Trail during this time and check out some of the other great trails in the area instead! Alternative parking will be available in the County lot on the west side of Hill Canyon Road. Thank you!
07/30/2024 - There's a new access route to Paradise Falls! Instead of the traditional way from the Wildwood parking lot at the west end of Avenida de los Arboles, access is available from our trailhead in Hill Canyon. The trailhead is located on Hill Canyon Road off Santa Rosa Road in Santa Rosa Valley. This route eliminates the descending (and climbing on the return trip) and is instead a much flatter option with a fair amount of shade along the latter portion of the trail. From the trailhead, cross the bridge to the south of the lot, continue south for about a mile, bear left at the junction, head southeast for about 1/3 mile, cross our new bridge, and then continue up the canyon to the falls. Check out the Wildwood trail map in the maps section of the website for more info!
07/29/2024 - Access to the Hidden Rim Trail and the Hill Canyon Fire Road from the north side of Rancho Conejo Blvd. remains temporarily closed. We are in communication with the property owner to resolve the issue.
New! Monthly Trail Work Opportunities!
In addition to our Fall and Spring trail workdays, we’re launching a monthly trail work program. The program will take on smaller projects with crews of approximately 20 volunteers. The expansion will provide more opportunities for community members to participate in trail work projects and provide COSCA the opportunity to address a variety of trail projects throughout our open space and trail system.
If you’re interested in participating, please register for events through the Conejo Recreation and Park District at www.crpd.org. Click the pink “Registration” button and search for “COSCA” to find event dates and locations. Each event will have sign-up limits so the number of volunteers is matched to the needs of the project. If you’re interested in getting alerts for upcoming volunteer opportunities, sign up with COSCA’s partners at www.cosf.org.
