CANCELLED due to Trail Conditions: Intermediate Mountain Bike Ride from Irvine to Limestone Canyon

We start our ride 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 the Box Spring which provides year-round water for wildlife like deer.

Oak trees provide shade and acorns, which the Indians used to grind into acorn meal. 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 down on Limestone Ridge, a fun singletrack that leads us towards the Augustine Staging area, enjoying views of Saddleback and Santiago Canyon. From there we will follow the Shoestring Trail to climb back up to Loma Ridge, and then coast back down on the paved Hicks Haul Road to our starting point.
