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.

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.

Andrea Wilson Triangle is a small protected area along Chaney Trail in Altadena. Though not a developed trail, it’s part of a larger effort to preserve open space and wildlife habitat in the foothills near Angeles National Forest.

Mostly smooth fire road through Monrovia Hillside Wilderness, but with some steep and technical sections that might challenge beginners. Ride counterclockwise from Canyon Park and follow the signsβ€”many side trails cross private land. The descent includes tight switchbacks and a short singletrack section. You can stick to the main road or take the β€œadvanced” trail, Cactus Road, for more climbs, exposure, and a fun technical finish.

The road south creates a nice, fast, gradual descent from the north side of Altadena. Just be safe and keep an eye out for cross-traffic at the intersections.
