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.
