This loop is my favorite after work ride for many reasons. It’s only 7 miles and it has a perfect combination of trails. You get your steady, extended climbing on well-maintained fire road, some killer single track, a fast downhill ride on Telegraph, and one last brief, but tough climb to complete the loop. In about an hour or so, you are done and you get a great workout. There is plenty to enjoy and explore in Chino Hills state park including classic trails like Raptor Ridge, North Ridge, Bane Canyon, and Scully Ridge, just to name a few. The South Ridge loop is also great for the beginning to intermediate rider who is looking to take their skills to the next level.
