Trail Description
About this trail
This is considered a "beginning" mountain bike trail in the San Gabriels, where most everything is just up or down. After you get your bike and out of your car, go past the yellow gate, and go down the pavement for just under a mile. You'll pass JPL to your left, and several other pseudo-trails on your left and right that don't go anywhere.

You'll reach a fork in the road, and take the left fork. If you take the right fork, you're on the wrong trail. Continue through the wide double track, and you'll be in the forest in no time. At about 2.5 miles, you'll hit your first creek crossing (there are five). The first three are pretty close together, and the second one is usually the worst. The higher you go, the more technical the trail gets. There is one area after the fourth creek crossing that I call "Satan's rock garden" because of the amount of rocks you have to go over with slick wheels from the creek.

Towards the end, the trail becomes singletrack, but it doesn't last long. You'll reach the sixth creek crossing, and you can continue on, but it's a lot of hike-a-bike from that point on.

Turn aronnd, and enjoy the downhill. Just becareful of all the dogs off-leach (no, they're not supposed to be), the horses, the hikers, and all the kids who leave their bikes in the middle of the trail.

The best part about this trail is it's the only shaded trail in the area, which is really nice on a hot summer day.

Review: Was on this trail a week ago after the first week of rain. All of the rock gardens got harder where the trail washed out. The creek crossings were insane and where the trail didn't flood to what appeared to be about 6 feet, it slid and slid. Definitely large pieces of trail missing, new boulders in the middle of flowy downhill sections, and a lot more challenge as the usual hardpack is covered in rocky debris. One old roller looked like it was ruined by a torrent of water and is cut a few inches deep now and sent me over the bars when my wheel hit it and bounced my bike back under me (definitely a hard part of the trail on the return as you now have a cut directly to a small upward rolling hill.) Beginners will walk a lot of this trail in the weeks until the trail smooths back out.

Review: Haven't really ridden this trail since it was washed out several years ago. This is no longer a beginner trail, I would say more blue square. Much more fun than it was before, if you are a fairly good rider. Rocks every where, sand every where, lots of shade, I love it. I would not recommend for beginners or kids, you will not have a good time.

Review: I've been riding this trail weekly for 2 years since I started mountain biking seriously and while it's certainly gotten lots easier as I become I suppose an "intermediate" rider, there's still plenty of fun and challenge to be had with the rock gardens, etc. I'm 54, pretty fit, riding a rigid single speed, and this trail is just about perfect for me and my rigid ss rig, unless I want more climbs. I can get some serious speed going on my ss on this trail (as long as I go during the week when it's not too busy with hikers).

Review: A bit more than a beginner trail. Either wide & sandy or narrow & rocky with a few creek crossings thrown in. Enough technical stuff to make it fun.

Review: I have been mountain biking for many years now, I would not consider myself a beginner. This trail was really challenging for me, lots of rocks all over the place, lots of walking the bike. I'm not saying it is extremely hard, but I would not call this beginner trail. Everyone can get off the bike and push it, I guess anywhere... In my mind easy means that you basically don't have to get off your bike. Am i wrong? I saw other bikers getting off their bikes pushing it. So it's not just me. If this is called easy then I can't imagine what a challenging hard trail is. Do you have to carry the bike above your head? I feel like rating a trail hard means then you basically can't bike just push your bike all the way.

Review: The recent storm washed the singletrack out pretty bad, too many trees and debris in the way to make this ride fun for beginners at the moment. This summer the trail should be broken in again for riders to fully enjoy.

Review: Flat trail along a creek - parts of the ride a unfortunately a bit littered up which is a bummer, but a great place to go with kids or people who just want to ride bikes, not really seasoned MTB vets.

Review: One of the few trail around here that reminds me of Northern California. It's definitely open again, and has plenty of shade and some creek crossings! Just stick to the main path.
