Come out and enjoy the evening with us on the Orchard Hills loop trail. This trail meanders around an avocado orchard on the edge of the open space preserve and provides fantastic ridge-top views of Irvine and the Pacific coastline.

The three-mile loop has several very steep climbs and uneven terrain. This hike is done at a moderate pace. Your effort is rewarded with a beautiful, unobstructed view to the west. This hike is not suitable for children under 12. Wear sturdy, closed-toed hiking shoes, bring water and a red LED flashlight.

Ready for a workout? Forget the gym for the day and head outside! Join us for an exhilarating morning fitness hike on the paved Hicks Haul Road in OC Parks’ Irvine Ranch Open Space. This hike allows you to choose between a 3, 6, or 8 mile route, all of which are conducted at the speed of about 3.0 to 3.5 miles per hour. The footing on the asphalt paved road is smoother than dirt roads and single track trails normally found in Limestone Canyon Nature Preserve, but is beginning to show its age with cracks, crevices and an occasional dip. Otherwise, the terrain is smooth, so this is a great walk for anyone who wants a “wilderness experience” without getting dirty! The 6 and 8 mile routes experience two fairly steep ascents and descents. The 3 mile route takes you to the top of Loma Ridge and back down. Along the way, you will have sweeping views of much of Orange County and the Santa Ana Mountains. Various animals, like hawks, deer, and lizards are also frequently seen in this area.

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.
