“A easy tour around the outside of Irvine Regional Park.”— John McKinney
Family Friendly Though perhaps a bit long for short legs, the hike has mellow grades and escapes the hubbub of the main park.
Monday to Friday the fee to park is $3 per vehicle, and Saturday and Sunday the fee to park is $5 per vehicle. Rates may be higher on holidays or for events.
Remember, many of the trails are multi-use, so know the right-of-way rules and be aware of other users.
At 0.8 miles you'll reach Watertank Lookout. Enjoy the views then continue on the trail; Puma Ridge Trail will join from the south at 1.1 miles. At about 1.3 miles the trail meets Peters Canyon Road. Follow this as it turns north and then west. The trail branches off at 1.8 miles continuing northwest.
Many trails intersect this trail, just follow the main path for Horseshoe Loop Trail. At 2.5 miles at the junction, turn right to head west on Santiago Creek Trail, then at 2.7 miles turn right again to take Roadrunner Loop Trail north. This parallels the road before crossing it to reach the main trail. At the junction, go right to take the eastern leg of Roadrunner Loop Trail north; this leg is better defined than the western one. At about 3.4 miles turn left to stay on Roadrunner Loop Trail which briefly heads west before turning south. Take the western leg of Roadrunner Loop Trail south through willows and riparian growth. At 3.9 miles the trail crosses a connector trail and then turns east. Cross the road and head south to meet Santiago Creek Trail.
At the junction turn right to head west on Santiago Creek Trail, which in about 0.1 miles intersects Horseshoe Loop Trail. Turn left to head south on Horseshoe Loop Trail; it turns east at 4.6 miles and crosses the main park road near the Park Office. At 4.8 miles you'll intersect and turn left onto the trail that heads back to the parking lot.

An assortment of fauna can be seen in the park if you head to the Orange County Zoo! Let's hope you don't see of these unusual critters while out on the trail though!
