Climb challenging State Spur to Cathedral Rock, and then descend into Fremont Canyon while passing some of Orange County’s most spectacular geological formations. The ride continues out to Mini-Moab and then over to Sierra Peak, passing the Tecate Cypress forest, then past Sierra Peak, and over to the last descent down through historic Black Star Canyon.
