Mostly smooth fire road through Monrovia Hillside Wilderness, but with some steep and technical sections that might challenge beginners. Ride counterclockwise from Canyon Park and follow the signsβmany side trails cross private land. The descent includes tight switchbacks and a short singletrack section. You can stick to the main road or take the βadvancedβ trail, Cactus Road, for more climbs, exposure, and a fun technical finish.

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.
