CORBA is an all-volunteer non-profit organization serving the mountain bicycling community of Los Angeles and its surrounding areas including Southern Ventura County. We are dedicated to preserving open space, maintaining public access to public lands, and creating more trail opportunities for all to enjoy.

We are passionate about the mountain biking experience and the mountains and trails that are available to us. We are also committed to our community and offer several programs that give back and contribute to positive trail experiences for trail users.
