Starting at the Ortega Highway, the road climbs steadily, passing Blue Jay USFS Campground. This is the only campground along the trail. If you need to camp, this is it. As you move further up towards the first peaks namely Trabuco Peak, the only vegetation you find are the low shrubs of manzanita and sugarbush. This is a fairly simple trail, though narrow with some loose, uneven surfaces. Your stock 4WD should do a good job here. For the more adventurous, you can use the numerous alternate trails crisscrossing the main one.
As the trail starts to climb, look down into the Temescal Valley towards the east. Lake Elsinore comes into view 2,000 feet below. Keep moving along and on a clear day you can see Mission Viejo, the Joaquin Hills and even the Santa Catalina Island. To the east is Lake Mathews.
When you reach Santiago Peak, the incline reduces and the trail normalizes as this route is used to access the radio towers located to the north.
While you drive along the trail, you might want to pull out and take in the exhilarating views. You can do this easily when you drive along the high ridge east of the Gulf of Santa Catalina. If you want to fully enjoy this trail make sure you do it on a clear, crisp winter day. The cool air and good sunlight will make it a great experience. Moreover, the sweeping views of coastal Southern California are not to be missed.
