Chantrey Flats is the natural end for those riding the Sturtevant Trail. If you shuttled to Mt. Wilson with a friend then this is likely the end of the line for you. Others might need to ride back down to Altadena if they took the shuttle offered by SCOAoutdoors.net. And still others might be climbing their way back up to the top via the myriad of roads and trails that depart from this picnic area.

The Lower Monroe Truck Trail has a mix of terrain, starting with a flat, rocky doubletrack section that transitions into a gradual, twisty eight-mile climb up to Glendora Mountain Road. It starts with a 1.7-mile rock garden creek section; the trail features intermittent tree cover and narrows to singletrack in spots. After a sharp right turn, the trail climbs steadily for 6.2 miles, mostly exposed, with great views of the San Gabriel Valley at the 3.3-mile plateau, a popular rest point. At the top, a gate marks the turnaround for the fast-paced, twisting descent. Riders navigate rocky and rutted sections with trail-hugging vegetation, so gloves and water are essential. Be ready for the occasional pedestrian encounters, a cowbell comes in handy.
