“A public dirt road that slowly ascends into Trabuco Canyon under a canopy of trees.”
— David Gregg
From Holy Jim Canyon back to civilaztion, this trail becomes a well-used public road that can be ridden faster on a bike than driven in a car. I wouldn't recommend this trail by itself, but as a cool-down from a long, hard ride it's just the right speed. This road parallels Trabuco Creek and its first half is mostly covered by trees except for the last few miles, which are completely exposed on the dry river side.
Hopefully you've set up a shuttle with friends and you can now either stop for recovery food around the corner at the local cantina, or make your way back to Silverado Canyon to retrieve your other car.
