Hi-Yo Arroyo Trabuco Professional Guide
Detailed Trail Description from our Guidebook
"Hi-Yo Arroyo Trabuco crams a little bit of everything into a 12.05-mile loop in Rancho Santa Margarita. The route includes paved roads, paved paths, and dirt trails—the trails include wide-track and singletrack, both flat and steep.
As suggested by the title, the ride’s feature is the Arroyo Trabuco, which is a seasonal wash that contributes to draining the Santa Ana Mountains. (“Hi-Yo” was, of course, the Lone Ranger’s signature shout-out to his horse, Silver—the equestrian equivalent of an ignition switch.)"
