Trabuco Canyon is one of the most beautiful places in the Santa Ana Mountains. The Trabuco Wash ride from the street to the Holy Jim parking area is a great Beginner ride featuring a gentle climb, a lot of it under the canopy of Oak trees. But once at the beginning of the Trabuco / Holy Jim Loop, the terrain becomes a more Advanced type of trail. Trabuco is a narrow, steep and rocky climb with cliff edges in some parts that is challenging even to the most fit riders.
