San Mateo Peak
San Mateo Peak (elevation 3,591) is the unofficial name of the highest point in the Santa Ana Mountains south of the Ortega Highway. Despite the panoramic views from the top and peak’s proximity to the heavily traveled Ortega Highway, the mountain remains somewhat off the radar of So Cal hikers, not being mentioned in any major guides. The trail appears to receive light but regular traffic from hikers, mountain bikers and equestrians. A few spots are rough but overall it is in good shape and easy to follow.
Begin on the Morgan Trail, following it for 0.2 miles through pleasant rolling terrain. Just before the register box, take a hairpin left turn and follow an unsigned trail. A few tree branches block the way but they are easy to bypass. A sign reading “Rancho Cap. 2, Loop 5” can be seen on the left. The trail follows the upper reaches of Morrell Canyon, passing through more attractive woodlands, crossing the stream bed a few times. At 0.4 miles, turn right at a T-junction and follow it deeper into the woods.
At 0.7 miles, take a hairpin right turn on a trail marked with a dinosaur(!) The trail soon leaves the woods, climbing sharply to a bench where you can see the ridge of San Mateo Peak to the left. You pass another dinosaur on a post as the trail continues to follow the exposed ridge, providing views of San Jacinto Peak and Lake Elsinore to to the east.
At about 1.5 miles, you dip sharply, dropping about 50 feet. After crossing the saddle, you begin your final push to the summit, climbing 400 feet in 0.6 miles. At the summit, a wooden marker generously lists the peak’s elevation at 4,000 feet and a register can be found in a coffee cup, signed by about a dozen or so people monthly.
The wide summit is strewn with boulders that are easy to climb; from this vantage point, you can enjoy a wonderful 360-degree panorama. If visibility is good, you can see (clockwise from the south) the ocean, Catalina Island, the northern Santa Ana Mountains, Baldy, San Gorgoino, San Jacinto, the Santa Rosas, Palomars and Cuyamacas. After enjoying the view, retrace your steps, exercising appropriate caution on the loose, steep sections of the trail.
