View of the Reservoir

Peters Canyon Regional Park is centrally located in the city of Orange, near foothills of Tustin and Irvine. Because it’s located smack dab in the middle of Orange County, and because it actually has some decent hills with views extending to the coast, Peters Canyon is one of the more popular places to hike in OC. The trail described here is a lollipop-loop, returning along the original ridge that you hike out on. For an easier hike, or just to mix it up, you can alternatively hike the canyon trail rather than the ridge line.

Peters Canyon History

The land that is now Peters Canyon Regional Park was part of a Spanish land grant, Rancho Lomas de Santiago. In 1897, the rancho was purchased by James Irvine, who leased out the canyon to several farmers, including James Peters, who farmed in the upper part of the canyon.

To support Irvine Ranch’s water needs, two reservoirs were built within Peters Canyon. The upper one was completed in 1931 and the lower one in 1940. Both were used to regulate the Irvine Company’s water supply draft from Santiago Reservoir, known today as Irvine Lake. During World War II, Peters Canyon was used as a training area for the U.S. Army. Known as Camp Commander, it was established near the lower reservoir.

Hiking the Peters Canyon Loop

The official entrance to Peters Canyon is on the north side, with ample parking on a gravel lot for $3. This hike begins at the southern entrance, with free street parking. You could easily begin this loop from the north side — just review the map linked below for details.

After parking on Peters Canyon Road, you’ll see a sign for the trail at the end of the street. There is both a paved bike path as well as a well-groomed dirt trail at the beginning, winding around a catch basin (formerly Lower Peters Canyon Reservoir).

The Beginning

As you wind around the catch basin, you’ll bear right through an opening in the fence and up a hill covered in eucalyptus trees. Follow this up the hill to the ridge line.

Looking forward to our first hill

The trail follows the ridge line parallel to the toll road. You may be able to hear the cars, but the tollroad itself is well-concealed by a berm, making this trail all the better.

The Trail Ahead

This ridge line offers tremendous views, especially on a clear day. You can see the San Bernardino mountains to the east, and even Catalina Island to the southwest. No wonder this trail is popular!

Working your way down towards the lake, you’ll take the Willow Trail. During the winter months, it looks quite bare, but this grove of willow trees will require you to watch you head in places. Be sure to stay on the trail here; there are patches of poison oak, and you can pick it up even when there are no leaves.

Stay on the Trail

When you emerge from the Willow trail, bear left and cross the main parking lot. The trail starts up again on the northwest side of the lot.

You make your way around the lake, up and over a pretty decent hill and back down into the canyon. At the junction of the Peters Canyon trail, you have a choice: return via the more rigorous ridge line trail or take the easier canyon trail? I chose the ridge line, but either trail will take you back to your starting point.

Ridgeline or Canyon?

The views on this trail can be pretty awesome. It’s easy to forget you’re in the middle of suburbia.

About Peters Canyon Regional Park

Peters Canyon Regional Park is open from 7am to sunset, seven days a week. Like most parks in Orange County, it is closed for three days following rain. The trails are open to hikers, mountain bikes and equestrians, so plan accordingly. Street parking on Peters Canyon Road (the “back” entrance) is free, but read the signs to avoid a parking ticket. The park has paid parking for $3 on the north end (the “front” entrance).

Getting to the Trailhead

To get the “back” entrance used on this hike: From the 5 Freeway, exit Tustin Ranch Road and head towards the foothills. Drive approximately three miles. Get in the left hand lane and turn left on Pioneer Way. Get into the right lane and take the next right on Pioneer Road. This road will wind around Cedar Grove Park. Continue to the first stop sign and turn left on Peters Canyon Road. Take this road down around a little curve and park on the right side of the curb at the end of the road. There is a sign for Peter’s Canyon Trail at the end of the road. Pay attention to the “No Parking” signs, as tickets are issued frequently to those who park in that zone.
