Tips from the Community
Short tunnel on the eastern slope below San Gabriel Peak, part of the old Mt Lowe Motorway, that was never paved. The tunnel is very short, so you don't have to worry about bringing light. The road continues to the trailhead half a mile uphill.

Tight, rocky, and exposedβthis oneβs a classic if you like your rides technical. The climb is tough, but the views are worth it. Watch for hikers, take the switchbacks, and ride early if you want to avoid the crowds. Not for beginners, but a fun challenge if you're up for it.

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.
