This one is fine if you want a quick hike. It’s very pretty but the graffiti everywhere is a huge bummer

Not a bad trail for a full day. Would of been a 5 star but you walk along the 5 freeway. Otherwise beautiful views through the hills.

Probably awesome for trail running... As a hike it's pretty boring. Not very scenic. Keeps you in the lower foothills for one half and then in between 2 golf courses and the 5 fwy for the second half. There is a tunnel that is flooded in front of the new zoo. You literally have to get off the trail and cross in front of the 5 fwy off ramp / on ramp to get around it. As far as the old zoo...there are much better trails that you could incorporate with that to make it more fun.

This is longer than 7 miles. One tunnel by the new zoo is flooded.

First half was good. We added bee rock to our hike. The coming back to the car through park playgrounds and the golf course parallel to the freeway sucked. Just wasn’t the atmosphere we were looking for. Seeing the “ruins” of the old zoo was awesome.

we did this on Christmas Day and if was a little rainy but it was surprising how many people were up there hiking and some pretty nice views and it greened up real well because of the rain

Great loop ! The outlined trail is not accurate when you get to Old Zoo Trail. There are a lot of little trails that go everywhere, I would suggest staying on Old Zoo Trail and coming out on paved road that leads you to Crystal Springs Dr. I got 7.2 miles and 664 ft elevation gain. There is little bit of everything in this loop, definitely will be doing it again. You can also start from anywhere and cut it shorter or add more mileage easily.

The former zoo is a bit disturbing, but is fortunately a very small part of the course mapped. The course is definitely easy to moderate. 90+% fire/horse trail. I would enjoy this one again.

I only give this 1 star. It's more of a walk/run than a hike. The last part is walking/running on a trail off the street between two golf course. I recommend if you want to truly hike. Make it and in and out with a couple of the other trails mixed in. There are many trails that branch off this loop. Don't take the loop unless you just want the miles.

a lot of horse shit. especially in the beginning of the trail. a long walk by the road and it smells like gas.

Great trail to walk your dog. Views include the 5 N and the valley. There are horses on the trail, make sure you move out of their way and your dog doesn't spook them. My dog sat in awe as I fed him treats and he watched them walk right past him. Stay away from the sides of the trail, rattlesnakes like to hide in all the leaves.

This is a nice long and convenient hike. There is some shade (by LA standards). The trail is not well marked so we go lost several times. There were not a lot of people and the trail was very well preserved.

Way too many people on the trail. If you like nature then don't come on this trail because there's not much of it.

Easy hike there is no shade, but the old zoo is the major attraction..

Super chill trail. I’m always cautious about hiking alone but you’re never too far from the main road. There are some narly steep inclines (not many). Good for trail running, except some parts are very grainy & sandy so traction isn’t the best at certain points. Fun hike though, good sight seeing :)

Beautiful short trail. This was a nice Sunday mid day hike. You are next to the freeway so expect to hear it. You also get a cool view of Burbank once you hit the top. Also lots of wildflowers are blooming!

Great hike, but don't leave anything in the car. My dumb mistake. I left my purse in the car...covered, but someone smashed the window and stole my purse and boyfriend's backpack. Just be aware.

CW direction (above Ventura Hwy) is nice. CCW part is awful. Be sure not to park on museum parking (it closes at 4 pm).

great trail for the first half or two thirds. after that is freeway side path back. dont worry too much about going on the wrong trail, most of them come back together anyway. just keep an eye on the gps.

Great hike. If you follow signs you won’t get lost and if you get off track, jus explore a new place. This is a nice hike for early morning. No bikes allowed in the trail, which is great. As the afternoon approaches you will encounter horseback riders, just remember they have the right-of-way. Enjoy.

Trail was very confusing at points and covered with horse poop for the first 2.5 miles. Most of this hike is directly next to roads, but the zoo part is cool and the trails are pretty
