This route consists of nearly every singletrack and fire road that the Chino Hills State Park has to offer. The rollercoasters on the South & North Ridge fire roads require a constant leg and lung effort but the views and pleasant singletracks make this route a must! Expect gorgeous scenery and marvelous views as far out as Santa Catalina Island. The final 3.5 miles of the ride is arguably one of the best fire road descents available to mountain bikers. Special thanks to Sky King for sharing this route with us.

Was quite surprised with the weather there. At home it was quite warm but in Chino seemed like it was going to rain. No rain but quite cool.
Nice long solo ride Wednesday. Little bit of a brake pad problem but rolled it all the way back to trail head. Thought for a minute I might be walking home in the dark!
Last half hour in dark.
Nice to do for a change.
Nice day for a ride.
