El Cariso–Trabuco Peak Epic Professional Guide
Detailed Trail Description from our Guidebook
"The El Cariso–Trabuco Peak Epic is indeed that. Give yourself plenty of time to complete this 32.8-mile clockwise loop that travels from Temescal Valley into the Santa Ana Mountains, and back down. The ride opens on the road, then goes off-road to head up into the mountains, and to descend, and then finishes with a short road segment.
The net elevation difference of 3,325 feet is the greatest of any in this book. The high elevation of 4,474 feet is reached as Main Divide Road North passes by Trabuco Peak, which is the third highest in the Santa Ana Mountains."
