Prepare for a lot of up and down on this trip through the center of Whiting Ranch Wilderness Park.

This short but challenging hike leaves from Concourse Park in Portola Hills, and provides a lot of nice views of the Santa Ana Mountains and the surrounding area, in addition to being a good workout.  The trail is almost entirely exposed, so plan accordingly, especially if the weather is warm.  Since most of the climbing is done on the return, this can be a good late afternoon hike as long as you are back by sunset.

From Concourse Park, follow the fire road heading down into the canyon. Soon you pass by a sign indicating the entrance to the park. As you descend, you’ll get great views of Dreaded Hill and the other sites of the park.

In 0.4 miles, you reach the bottom of the hill. Head right and then immediately left on the signed Edison road. A steep ascent brings you to a hill where you get nice views of the area. You curve around the side of Dreaded Hill and make a more gradual descent to the trail’s end. The destination may seem a little anti-climatic, but you do get nice views of Lake Forest, Irvine, and on clear days the San Joaquin Hills.
