Chino Hills State Park has over 60 miles of trails that work their way through the park. This route uses the main fire road (Telegragh Canyon) and picks up the Raptor Ridge singletrack at Four Corners and drops into the campground. The climb out of the campground on the South Ridge fire road is steep in places.
Need to Know
Parking is $5.00 at the Discovery Center located at 4500 Carbon Canyon Road.
Although this ride is mostly on dirt road, it's a nice cruise through the state park, and worth checking out.
Telegraph Canyon is a gentle climb that passes through Oak trees and along a creek (dry most of the time). Be aware that poison oak is very prevalent in the park. There are several ways to rejoin Telegraph Canyon from South Ridge if the climb on South Ridge takes its toll.
