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. .

The first 2 miles are not very nice and very crowded. Stick with it, the trail becomes lovely after that. Loved crisscrossing the creek. Be prepared for wet feet. :)

it is hard to find shaded trails in southern California. this is one of them. Be prepared to cross streams with water. A great trail to experience wilderness within 2 miles of starting on this trail. limited parking near trailhead but plenty on the street. if hiking with kids, consider doing a short distance. many picnic benches on the route .

My family and I did about 2 miles of this, ages 8 & 9 and grandmother. Easy walk by a stream, however, we went after the rain and it was like a river. The river actually made it impossible to pass at the 2 mile mark without getting wet up your knees. So we turned around. Can't wait to come back

My 4 kids and I went up with our mountain bikes and had a blast. Definitely loved the terrain. Water streams strong and high thanks to all the rain. So be ready to get wet and push through.

The description above states that this is a 20 mile moderate hike. However, the group I went with today took the cutoff to Paul Little camp ground and the trail ended at a man made dam/waterfall, which is less than half that distance round trip, and it is an easy fairly level trail.

After years of being a couch potato, I started hiking again only about a month ago, and have bad knees and bad back, so the group pace was a bit fast for me. The furthest I had gone previously was 5 miles, so I thought the touted 7 mile round trip would be a sizable jump for me. However, it turned out that from my car in the middle of the lot till I got back to it exactly 4 hours later is, according to my pedometer app, 9.7 miles, which was a huge jump for me. Granted that towards the end my steps were probably getting a bit shorter, but I still guesstimate that the distance was probably between 9 and 9.5 miles. Probably closer to 9.5. I figure that I was at least 20 minutes behind the group, since I got a text about 15 minutes before I got to the car, from one of my carpoolers that they were taking Uber.

I highly recommend this trail for beginning hikers and those like me who have injuries. I also recommend that they go at their own pace rather than trying to keep up with a group of people, unless that group consists of equally slow hikers. I wish I could find a group like that.

Rocky in places, but so beautiful. It was so refreshing to see, hear, & smell the wetness of the streams. Glad I brought water for my husband, myself & for the dogs. Dogs love the hike. We are in our 70's & felt it was mostly an easy hike. We go usually on the week days. Much less crowded.

Cool hike that I didn't find to be too crowded. my son enjoyed it, and the scenery changed enough that it was diverse enough. We actually backpacked into Golden Mesa, setup there and hiked to the "waterfall". it was pretty nasty... the kids all ran under it, but it looked like it was just a runoff and the whole cement wall was covered in algae.
