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 Mtβ€―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.

For a ride with history and views, check out the Ye Alpine Tavern ruins in the San Gabriel Mountains. Once a popular mountain resort, it burned down in 1936 and was later demolished, but you can still spot the stone fireplace, foundation, and water tank.

Great view of Downtown LA. The climb up into the hills to reach the viewpoint is challenging, but it is worth the effort for the excellent vistas.
