Clevenger Canyon is part of the Coast to Crest Trail of the San Dieguito River Parkway, a 70-mile trail that will eventually connect Volcan Mountain with the ocean at Del Mar. The Clevenger Canyon North trail has suffered from frequent fires and vandalism. Despite these degradations, it retains a number of attractions that make it worth a visit. Ignore the graffiti and take the short hike down to and along Santa Ysabel Creek. It is rich in wildflowers and blooming chaparral shrubs in season. The stream, whose banks are lined with oaks, willows, and sycamores, provides shade on hot days. The trail from the stream up the side of the canyon is a challenge some hikers will avoid, but if you do it you will be rewarded with amazing views as well as some vigorous exercise.
The trail descends quickly from the parking area. After passing through a short rock-framed tunnel and going down some stone steps, the descent becomes more gradual, reaching Santa Ysabel Creek in about 0.25 mile. Be sure to look for vines (wild cucumber, honeysuckle, and virgin’s bower) draped over yellow-flowered bush penstemon, mission manzanita, California sagebrush, or scrub oaks while hiking the trail. Some of the wildflowers you might see include wild hyacinth, larkspur, golden yarrow, wild heliotrope, wishbone bush, and white pincushion.
You likely won’t find a bubbling stream when you reach the canyon bottom. During drought years, you are likely to find only damp sand. Still, there is enough moisture remaining to support a forest of tall sycamores and both coast live oaks and Engelmann oaks along the stream banks. A dense growth of arroyo willow, wild grape, and false indigo grow under the trees. This oak woodland forest is a green ribbon running through Clevenger Canyon, up to the San Pasqual Valley Agriculture Preserve that begins just to the west.
The trail stays only briefly in the canyon before climbing up the bank and out of the forest. It follows the creek along a bench about 50 feet above the forest before ascending the south-facing slope of the canyon. It continues up this steep hillside through a series of switchbacks. This part of the hike can be strenuous and a good place to turn around if hiking on a hot day. It is about 1.25 miles to the top of a ridge, with about a 1200-foot gain in elevation. There is no shade and you are likely to be in the sun most of the way. Also, the trail becomes progressively indistinct and hard to follow near the top. Be sure to check your backtrail as you proceed to the top so that you can easily find your way back. A few years back the trail continued for some distance on top of the ridge, extending to three viewpoints, but wildfires led to the abandonment of this part of the trail. Still, you will be rewarded upon reaching the top of the ridge by views of the San Pasqual Valley and the surrounding hills. When you have rested, retrace your steps to your vehicle.
