Many switchbacks are loose dirt, but otherwise KB trail is mostly rideable. Plenty of poison oak, but easily avoided if paying attention. Also pay attention to log placement to avoid wasting time missing trail as it leaves stream bed.
It was an easy hike, just really exposed for the majority of the time, so bring water and wear sunscreen. Dog friendly (which is awesome) and horse friendly (which is what I didn't like about it because there were massive piles of horse dung all along the trail). Once you go through the tunnel, there's a gate that is typically locked with a no trespassing sign, so go down the trail and take a right along the dried creek to get to the gate. Don't go under the bridge, because that's a different trail and I'm not sure where it leads. It's pretty cool. I'd recommend it.
Nice walk. A little difficult to find which is great. My friend and I were the only people at the rock. I wish they would clear the brush a little better. Pretty soon the path will be very difficult to find and get through. Other than that, it was nice and did get a little creepy after playing with the echoes from the wash behind the gate. The echoes are unlike any other tunnel or echo producing structure. The vibes were a little intense.
Great trail. Loads of options to make the hike more extensive and challenging. Some shade but a lot of exposed trail. Looks like there are some nice single tracks for mountain biking. Trail is dusty and there are some rocky areas so wear good trail runners.
I really liked this little haven. I went twice already. It looks sketchy hiking in threw the angles crest direction. But I seen many park over night with no wilderness pass and got no ticket. How ever I wouldn't recommend it. Lots of shade .. Even in the drought there is water. Drops into a campground and if you follow through it ll drop you off nearly next to JPL. Lots of spots to explore.. Campsite super small.. 5 sites I think... There's bears, cougars.. These are the San Gabriel mountains so be cautious..
This trail isn't exactly breathtaking. It is definitely on the creepy spooky side. There are stories of children who have disappeared and various ghost stories. I recommend bringing a friend or coming in a group. It's interesting. The damn in the bridges are really nice features.
I jog this trail almost very day. The views are beautifull. I go at all times of the day & sometimes run for three hours & never see anyone. When the moon is full, it's heaven. There is a horse trough & dog & people fountain at the Ultimate Destination Trail. There's a great training mountain on Descanso Trail. Yes there is the practice gun range but it is occasional. The people are super friendly!!! Cherry is KING!!!!
