This route starts on Skyline Road (fireroad) from the Corona side of the Santa Ana Mountains and meanders up to Main Divide then Beek's place (a remaining stone foundation of an old structure). There are great panaromic views that range from Mt. Wilson to San Jacinto, with Mt. Baldy and San Gorgonio in between. On the way back down, there are some exceptional and challenging singletrack sections which parallel the road.
11/25/14 Ate it riding down skyline in the dark today. The bike got away from my center of balance and my front wheel lost traction. My forehead hit the ground pretty hard. My helmet saved my Mellon. Walked away with only scratches on my left finger knuckles due to wearing open finger gloves. Bike no problems. I may consider more aggressive tires going forward. I'm running tubeless Specialized Ground Control tires now.
