This is a nice shaded out-and-back trail in the lower part of the Angeles Crest Highway. The first part is a fairly steep incline but is completely shaded. It becomes a more gradual climb up over the saddle and down into grizzly flats.

Good trail. Steep start then you get a nice descent and a flat before doubling back. Maybe 1/4 shady so wear hat and sunscreen. Lots of bees, both honey and carpenter. Great flowers along the trail, very mildly overgrown at points but nothing too bad.

Beautiful trail with aromatic wild flowers and gorgeous scenery. Steep downhill and overgrown with some fallen trees on some particularly steep slopes and narrow unstable trail with sheer drop offs and not much to hold onto. I believe there were 6 thigh-deep river crossings (water friendly/quick dry shoes are a great idea), lots of poison oak, red ants and stinging nettle (quick dry pants and shade hats are a good idea) It was beautiful and pretty empty. the end point was underwhelming and disappointing with trash, poop, toilet paper and some families with super loud music swimming and enjoying their afternoon. Not a problem except I wish it wasn't the end point of the hike. Bathrooms at the end point are open but NOT maintained right now because of the virus. Make sure to head out early and bring plenty of water as we head into the summer months- it's hot and full sun on a good amount of this trail. There are little shady spots along the way though.

Watch out for lots of poison oak about 2/3 through the trail. Beautiful wild flowers in bloom.

The coordinates on this page take you to the Dark Canyon trailhead, which is in a small parking area (~10 cars) on the western side of the Angeles Crest HWY (ACH). We hiked up the trail, turned right at a fork, and continued until we hit a wide, fire road. To continue on Grizzly Flat trail, we crossed the fire road and hiked down a trail marked with a post, 2N80A. Heading left on the fire road eventually takes you to Mt. Lukens. Heading right takes you back to the ACH via Hoy Mountain Road. The trail going down had pretty wildflowers, shade, and views of the canyon. The trail was overgrown in areas, and there were a few trees across the path and poison oak in some spots. We wore long pants and were fine. At the bottom, the trail crosses Big Tujunga Creek in about 4 different areas. It seemed harder and/or was not possible to dry cross on rocks so we waded through the river, which felt nice and cool. At our last river crossing, we came out to an open area and headed right. A few minutes later, we came upon another river crossing in front of the parking lot, which is the end of the trail. We didn't cross because there were a lot of people/families on both sides of the riverbank and, due to COVID concerns, we didn't want to get close to the crowd. Hiking back up the canyon was a slog, especially when plowing through the overgrown areas, but there were lots of shady places to take breaks. We went on a Sunday in mid-May 2020 and we saw 10-15 people total on the trail. This trail was fun and would definitely recommend.

Nice trail, but extremely overgrown in the second half going down. Wear tough long clothes or be prepared to be pretty scratched up. Easy to follow the trail though. Nice views and awesome little river pool for soaking your feet or getting wet.

Super over grown towards the end. Get ready for some scratches. Cool hike overall with tunnels of trees and bushes. Very quiet. Only saw 2 people (a couple).

As marked this trail starts from the lower dark canyon trailhead, not the grizzly flats trail which is a mile further east on the ACH. This is a reasonably steep climb to start, then it is down to Bug Tujunga creek over 2000 feet of descent. It is overgrown in places, but once you get past the grizzly camp ground the views of Big Tujunga and Silver Canyon are amazing. Right now the Big Tujunga creek is running fast, and there is no crossing it without getting wet. The hike back up is a grind, but the grade is actually not horrible, as much of it used to be a fire road and was graded as such. I think this would be less pleasant during the hot dry season, but right now it's impressive.

Most trials in this area seemed too busy to be able to social distance but we got lucky with this one! Didn’t take this exact route just kind of hikes around this trail system and went back to our cars but it was perfect outdoor time with room between others.

At about 2 miles in, the trees are so overgrown you have to walk completely bent over to duck down low enough to get through. We kept going for about half a mile, hoping it would get better, but I got sick of being hunched over so we turned around and went back.

Updating my review below. Starting at the turnout with the Grizzly Flats sign on the Angeles Crest, hike up the fire road and go LEFT at the fork. Soon you will be on the other side of the mountain (recent controlled burn here) and a bit further up at the saddle there will be a trail, left and right. The trail to the left is actually called Dark Canyon. Dark Canyon's trailhead is a quarter mille west (downhill) from the Grizzly Flats sign on the Angeles Crest and unmarked except for some stone steps. If you go right at the saddle this is Grizzly Flats proper but from this starting point there is a lot of chaparral pushed down making the trail a slog, so I turned around once again and took the fire road up to Mt Lukens which is a very good hike. Large, healthy forest and good views. Deer tracks the whole way. I think Grizzly Flats can be done from the other end, starting off at the creek along the road to Palmdale which is why some reviewers mention a lot of water to start.

Confusing but worth it. After the helipad, DON'T go right as another reviewer incorrectly states, GO LEFT and soon you will be on the other side of the mountains with nice views. If you start the hike on the fire road with the Grizzly Flats sign, I think the actual Grizzly Flats Trail intersects the fire road about a mile in. You'll come to a saddle with a trail going down to the right toward the creek along the road to Palmdale. There is a flat area here (could this be Grizzly Flats?). The trail also goes off to the left, through a lushly forested area (the old Christmas Tree farm a hiker told me about?) I think the whole of this trail (left and right) is the actual Grizzly Flats. I explored some of the tree farm area. It's a nice environment but chose to go back to the fire road and hike up the mountain. Technically a different hike, yes, but really nice. Just know that you should GO LEFT at the fork after the helipad and that there are no signs pointing out the actual Grizzly Flats trail. Also, I suspect that the real trail head for GF is back down the angeles crest, west a quarter mile where there are some shaded stone steps and not much else. I'll try that trail head soon and update. For the meantime, very nice views on this hike, JUST GO LEFT!

First part of the trail up to the ridge was being cleared by a group of volunteers as I hiked today, so much more passable now than some of the reports below. Still some slippery spots due to erosion and loose rock in the first bit of the trail.

Very nice trail and pretty steep at first. Did this last Thursday, 12/5 and ran into some areas where down trees completely covered the path. There was also a washed out area where the trail had slide down the side of the mountain. Be careful crossing it!

Did this for the second time. It’s slightly overgrown, but nothing you can’t get by. I still for the life of me can’t figure out where people get lost. The only possible confusion is where you cross the fire road. And that is marked on AllTrails. You just literally go straight at the metal post. Not left, not right. Not the prettiest time of year for this, but a good hike.

great trail if you do it early. we got there around 7am and finished around 11. there is plenty of shade most of the time and this would be an absolutely breathtaking hike during the spring as flowering shrubs line the majority of the trail. the bright yellow ones that smell so good. and the river which was small when we visited is many times bigger in the spring. HIGHLY RECOMMEND
