Here is a loop ride that takes you through the southeastern portion of Chino Hills in an area that offers isolated riding, and good scenery. The Sidewinder singletrack at the north end of ride can be quite overgrown but enjoyable and challenging. DIRECTIONS: Take the Riverside Freeway (#91) to the Corona Expressway (#71) north. Immediately after entering, you will see a left turning lane taking you into a large parking area. This is the start of a fun ride.

08/25/10 I actually climbed up the Overlook pass to east fenceline trail. This trail is fun but hardly used so you will ride through overgrown foliage. There are also areas you need to portage through but overall, fun.
04/04/10 One of the most scenic rides I have completed. One of the features is the overgrown vegetation that covers the trails. You'll encounter tons of gnats halfways through the loop. Try not to breathe them in!
