The Los Robles Trail Re-route Is Open!

The long awaited Los Robles Trail Re-route is now open and getting great reviews from our first riders and hikers. The re-route is located in the Southern Ridge Open Space and offers spectacular views of the Conejo Valley. The new trail segment can be accessed most easily via the Rosewood Trail. The trail passes over a private road in this area and visitors are asked to stay on the trail. The trail was built by COSCA's dedicated rangers along with the The CREW - Concerned Resource & Environmental Workers  and volunteers from the Conejo Open Space Trails Action Committee. Looking for a great hike or ride? Give this one a shot.  A map and more info are available in the press release.
