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.

Just below the Mt Wilson Trailhead on Red Box Road, this overlook and memorial is a perfect place to pause. Sit and take in sweeping views of the San Gabriel Valley, and read the memorial plaque honoring early conservation efforts.

Henninger Flats sits along the road with views of Altadena. You’ll pass by it while climbing the Mt. Wilson Toll Road and can take a moment to catch your breath while enjoying the views. The route features a steady climb with minimal shade, so it’s best to start early, especially in summer. At the top, enjoy panoramic views of the San Gabriel Valley and explore the area, which includes a visitor center, picnic spots, and a tree nursery.

There are lots of vintage shops and cafes in the historic downtown. Library Park is a great place to rest in the shade with a bite to eat before continuing your ride.
