Summary: This hike take you into one of the loveliest sections of the San Gabriel mountains. The hike meanders back and forth across the stream running down the spectacular Arroyo Seco Canyon. The stream is lined with oaks and alder, with the water cascading over granite into mirror-like pools. The hike travels high above the 50 foot high Switzer falls, where the trail bears right to head towards Oakwilde Camp.

The trail traverses the hillside high above the Arroyo Seco, then drops down into the densely wooded Long Canyon. At the junction of Long Canyon and the Arroyo Seco, a lovely two tier 50 foot waterfall drops down into a gleaming pool. The section of this trail between Long Canyon and the Oakwilde camp is considered to be the most gorgeous of the entire Arroyo Seco, with its souring walls, cascades, and dense woodland.

Trailhead: From Interstate 210 in La Canada, take Highway 2 north and drive 10 miles to Switzer picnic area on the right. Descend to the parking area outside the campground. You will see a footbridge over the stream leading to the trail head. (Lat:34.26609 Lon:-118.14559)

Mostly burned in fires. Surrounding areas also burned for miles. The trail is closed for now.

Hi, where does the trail split off to the Upper trail? My best friend and I broke off the trail and went along the trail at the only point there was a sign (on the really narrow path). We hiked along a very narrow and scary trail and it finally stopped after a rock slide almost fell on our heads (very scary).

My neighbor Nick and I did a 10 mile point-to-point hike from Switzer Camp all the way down the Arroyo to JPL in Pasadena. The past two days of heavy rains was a blessing and a curse. The scenery was stunning, with the big waterfalls roaring and many small waterfalls caused by the runoff. Thats the upside. The downside was that we had 34 stream crossings, with about half of them calf to knee deep. Nothing dangerous, but we definitely got wet. Took us 5 hours of steady hiking without a break. Definitely recommended!

I hiked down the steep use trail from ACH to Oakwilde. I then climbed the Ken Burton Trail and continued up a steep use trail to the top of Brown Mtn. From there descended to Tom Sloan Saddle and hiked down Bear Canyon. I reconnected to the Gabrielino trail and took it through the Upper Arroyo Seco. A wonderful ridge and canyon experience with lots of water!

(did hike on: 9-22-08)Awesome hike!!!! I really enjoyed this hike for myself. We jumped into the top of the waterfall that made a pool and was cold as hell, great experience!!!! There was beautiful sites and scary trails but all in all... VERY WORTH IT. Really nice people and good place to just lose yourself.

Excellent outing! We went down to Oak Wild and back. Lots of birds, lizards, and even trout!! Watch out for poison oak, and keep in mind as you casually make your down to Oak Wild, you have to come back up!! Makes for a great 5 hour hike! Our GPS tracked only about 9 miles, not sure why.
