We start our ride through OC Parks’ Irvine Ranch Open Space on the paved Hicks Haul Road, the extension of Jeffrey Rd north of Portola Pkwy. As we warm up on the climb to the top of the road, we enjoy increasingly beautiful views over Irvine. We then follow Loma Ridge to the East, with fantastic vistas of Orange County, the surrounding wildlands, and even Catalina Island on clear days. From Loma Ridge, we descend on a single track to Box Springs which provides year-round water for wildlife like deer.

After the springs, we continue to the Sinks, Orange County’s own “Grand Canyon,” where we enjoy our snacks during a short break. On our way back, we ride along Limestone Ridge, a fun singletrack that leads us towards the Augustine Staging area, enjoying views of Saddleback and Santiago Canyon. From there we will climb back up to Loma Ridge, and then coast back down on the paved Hicks Haul Road to our starting point. Motorized recreation vehicles of any class or type are not permitted for use in the Nature Preserve.
