Telegraph Canyon–South Ridge Loop Professional Guide
Detailed Trail Description from our Guidebook
"Enjoy a meandering stroll through 14,100-acre Chino Hills State Park, where rolling grasslands and groves of oaks and sycamores share history, natural preservation, and solitude. The preserve provides an open-space experience in the middle of urban Southern California. This lovely route travels through the heart of Chino Hills State Park, starting at Rolling M Ranch and making a 4.0-mile loop through rustic and peaceful countryside. The hills begin to turn green in January, just after the seasonal rains. A few short weeks to months later, the wildflowers are in bloom. Groves of oaks and sycamores are found in and alongside the canyons. During spring, the namesake rolling hills are verdant and green."
