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.

A solid entry to the Verdugo Mountains with rewarding climbs and views, but watch the startโ€”there are ruts and leftover metal pieces on the trail. Stay alert and pick your line carefully to avoid punctures or spills before the smoother sections begin.

Just below the Mtโ€ฏWilson 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. Youโ€™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 itโ€™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.

Cherry Canyon Park is an area of 130 acres in the San Rafael Hills, close to La Caรฑada Flintridge. It features multiple trails and fire roads for horses, mountain bikers and hikers, but also various single tracks that are only for hiking. From the trails, you will get a great overview over the area.

This tunnel was blasted into existence in 1942 to form the old Mount Lowe Motorway.

Great viewpoint from the top of Ridge Motorway. Once you complete the climb to the top, reward yourself with a short break to take in the great vistas. You will be able to see Burbank and La Tuna Canyon Park.
