It may seem hard to believe that the Santa Ana River, visible to many Southern California residents as nothing more than a cement channel that flows through Orange and Riverside Counties, starts in the depths of the San Gorgonio Wilderness.  Most people are familiar with the bike path portion of the Santa Ana River Trail, but the 28-mile stretch in the San Bernardino National Forest is not as well known.  The route here starts from Glass Road near Angelus Oaks and arrives at the San Gorgonio Campground.

From the parking area, cross Glass Road and begin hiking east on the trail. This section of the trail features both attractive stretches underneath pines and oaks and nice views of the canyon and the peaks–notably Sugarloaf–towering above. There are a few places where the trail clings to the side of the mountain and drops off sharply on the side, which will make you thankful for your poles.

After 3.2 miles of winding in and out of the canyons on the south side of the gorge, you arrive at an intersection.  Take a hard right onto a trail signed for the San Gorgonio and Barton Flats Campground.  The ascent becomes a little steeper here, reaching another junction in half a mile. Take a hairpin turn to the left, and walk the last half mile to the campground. This may seem like somewhat of an anti-climax, but like the Ernie Maxwell Trail in Idyllwild, this section of the Santa River Trail is more about the journey than the destination.

    1. Hi Todd, thanks for reading, liked your pix. I did write up the aspens as part of the trip to nearby Fish Creek Meadows, a nice four mile round trip hike, here.
