Concerned Off-Road Bicyclists Association - CORBA


The Concerned Off-Road Bicyclists Association was formed in August 1987 in response to threatened trail closures in the Santa Monica Mountains. CORBA was one of the founding clubs of IMBA, and was inducted into the Mountain Bike Hall of Fame in 2014. CORBA works in the Santa Monica Mountains, which includes State Parks, Mountains Recreation Conservation Authority, Santa Monica Mountains Conservancy, National Park Service, LA County, and Conejo Recreation and Parks District. We also work with the Angeles National Forest, Los Angeles County, and several smaller cities and conservancies in the area.
