Orchard Hills Loop (Irvine Ranch)
This hike explores the foothills on the south slope of Loma Ridge, above Irvine. Being on the suburban side of the ridge, this hike doesn’t have quite the wilderness feel that many other hikes on the Limestone Canyon side provide, but it’s still a good workout with some panoramic city views, especially at dusk.
The route has recently become one of the more popular ones offered by the Irvine Ranch Conservancy, with hikes scheduled almost every week, including morning, evening and night. A variety of routes are offered as well, ranging up to ten miles but most commonly the three mile-plus double loop hike described below. Since you will be hiking with a docent-led group, navigation won’t be an issue, but it’s still good to know what to expect.
As of this writing, an upgraded trail head is being built farther west on Orchard Hills. When opened, that trailhead will shorten the hike by about 0.5 miles; the elevation gain will be comparable. Begin by following the paved road out of the gravel parking area for 0.4 miles and make a hard right on an unsigned single-track, passing groves of avocado and eucalyptus trees. At 0.7 miles, continue straight as another trail (your return route) branches back to the south. A moderate ascent along a ridge brings you to a paved road and a T-junction on the opposite side; the start of the larger upper loop.
Turn right and head downhill toward some service buildings and turn left on a single-track trail that skirts the edge of the orchard. Some gentle meandering brings you the base of the steepest climb on the route, known as Orchard Hills Hill. You’ll gain 200 feet in about one sixth of a mile. If you have to stop to catch your breath, keep an eye out for sandstone caves on the opposite side of the canyon on your right.
At the top (1.8 miles from the start) your efforts are rewarded with a 180-degree view that may include Catalina Island, the Palos Verdes Peninsula, the Hollywood Hills, the Santa Monica Mountains, the Santa Susanas and the San Gabriels. A few eucalyptus stumps make for seats to enjoy the panorama.
When ready, continue by making a hard left and heading south, still along the edge of the orchard. You drop back down to the service road, completing the larger loop. Retrace your steps back to the previous junction and continue straight, climbing up a ridge with nice views of north Irvine before descending back to the service road. Follow it, passing by the single-track turnoff, for a total of 0.5 miles back to the parking area.
