Rancho Cañada del Oro Open Space Preserve

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

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 existing 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. Amenities will include an accessible trail, seating, and interpretation about the surrounding natural resources.

As a separate project, the Authority will look at the feasibility of providing access to the southern portion of the preserve. This will include an analysis of over five miles of existing ranch roads, and the potential for providing seasonal future access to rolling grasslands, blue oak woodlands, and mixed oak savannah in the preserve’s backcountry. In the future, visitor use will be open to hikers, mountain bikers, and horseback riders. Join our mailing list below to stay connected and get involved! 
This project is an example of how the Open Space Authority is Investing in Nature.
