Rancho Cañada del Oro Open Space Preserve

Planning and Design Underway for Llagas Creek Bridge Crossing to Provide Public Access to Blair Ranch

The Authority has kicked off the planning and design process for the first phase of expanded public access at Rancho Cañada del Oro Open Space Preserve. Once complete, this phase will provide visitor access from the staging area to the former Blair Ranch portion of the preserve.
The project will connect the Llagas Creek Loop Trail to a newly-installed bridge over Llagas Creek. Once across the bridge, visitors will find themselves in an enclosed grassland day-use area, nearly surrounded by riparian woodlands, or forested areas next to a body of water. From here, the trail will continue on to over 5 miles of existing ranch roads, providing seasonal access to rolling grasslands, blue oak woodlands, and mixed oak savannah in the preserve’s backcountry. Visitor use will be open to hikers, mountain bikers, and horseback riders. Future phases of planning for the preserve will evaluate opportunities for new trails, including connections to Sierra Azul Open Space Preserve, a parking area near the southern entrance, a backcountry camp, and other amenities.

This project is funded through Measure Q.
