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.

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.

Sturtevant Trail is one of the most diverse bits of trail in the San Gabriel Mountains. On the way down you'll encounter technical loose switchbacks, flowy sections, rock gardens, decomposed granite, and plenty of roots. Beware that this is a multi-use trail and can be busy with hikers, especially on weekends. Early mornings are the best time to ride, but always watch your speed, particularly around blind corners.

Mount Wilson is a 5,710-foot summit in San Gabriel Mountains. It's easy to distinguish from the other tall peaks around this area due to how many antennas is has near the top of the mountain. They don't interrupt your views once you're up here, though.
