"The trail follows beside, across, and through Borrego Canyon Creek and reaches the more open and undeveloped hillsides. Eventually you strike out onto the narrow and very scenic Red Rock Canyon Trail, which meanders through oak woodland and coastal sage scrub to 100-foot-high red sandstone cliffs in Red Rock Canyon. In 2007 the Santiago Fire burned nearly 90 percent of the park. As of this writing, the park is open and in the process of natural recovery. Please respect the process by staying on established trails and following park rules." Read more
"Limestone-Whiting Wilderness Park en compasses 4,000 acres on the north end of Lake Forest and Foothill Ranch in the foothills of the Santa Ana Mountains. The park, an old cattle ranch, contains riparian and oak woodlands, rolling grasslands, scrub-covered slopes, and dramatic rock formations. Four seasonal streams—Borrego, Serrano, Glass, and Aliso Creek—wind through the parkland canyons. Twenty-six miles of graded roads and foot trails traverse throughout the park for hikers, bikers, and equestrians. Borrego Canyon and Serrano Canyon are the two largest drainages in the parkland. This hike leads up Borrego Canyon to Vista Lookout, a 1,500-foot knoll on the northwest corner of the park. From the overlook are views of Red Rock Canyon, Limestone Canyon, and the Santa Ana and San Gabriel mountains. Viewing scopes atop the knoll highlight Old Saddleback, Luke Mesa, Caspers Wilderness Park, and Catalina Island. The Santiago Fire burned 90% of the area in 2007, but the landscape has been steadily recovering." Read more
"Red Rock Canyon is a narrow canyon surrounded by dramatic 100-foot red sandstone cliffs in Whiting Ranch Wilderness Park. The wind and water-carved formations cast a red terra cotta tint from oxidized iron in the rock. Shellfish and marine fossils can be seen in the fluted and chiseled sedimentary cliffs. To help preserve the fragile serrated outcroppings, Red Rock Canyon is open to hikers only. This hike follows stream-fed Borrego Canyon to its upper reaches in Red Rock Canyon. The trail winds under a dense canopy of twisted live oaks, towering sycamores, and willows to the weathered rock sculptures in Red Rock Canyon." Read more
"Like most trails in the Whiting Ranch Wilderness Park, the Borrego Trail is open to mountain biking and horseback riding, as well as hiking. Mountain bikers, however, are not allowed to ride all the way to Red Rock.
At the beginning, you immediately plunge into densely shaded Borrego Canyon, alongside a stream that happily trickles through the winter and spring. Often in the late fall and winter, frigid air sinks into these shady recesses overnight, and by early morning, frost mantels everything below eye-level." Read more
