We went there this Sunday morning to hike the shady trails. There were a lot of mountain bikers out. We were warned to beware of the fast moving mountain bikers that race down that shady portion of the trail. Beware - A section of that path is very narrow and having a cyclist and pedestrian there at the same time is trouble.
We turned back and headed up another path. Of course that was the sunny side. No big deal though. The views are beautiful and it’s always better to be outdoors enjoying nature.

Landed on this trail due to the closures of several Pasadena hikes today. We hiked the first 3.5 Miles, then headed back (which seemed to be a common turnaround for many). The trail actually extends 10 Miles to the Switzer Falls area. The first half mile is less than beautiful due to the proximity of JPL, but after that, you dip into the wilderness for what is a gorgeous, shaded, very EASY hike (more like a walk in the woods) that offers several stream crossings, wooded areas, and looming canyon walls. The air was at least 10 degrees cooler in the canyon, which was very refreshing. There are a few campgrounds along the way. This hike is good for most skill levels, is suitable for dogs, bikes and joggers,. The trail is a mix of single track and walk-and-talk. .
