This trail is incorrectly named. The trail as marked only goes up to Brindle Peak where the TV transmitters are. Actual distance to Sunset Peak is 12 miles one-way. You can make it a one-way 15-mile hike to Sunset Peak trail head on Glendora Rd just West of Mt Baldy Village. You can also make it a 16-mile one-way hike to Mt Baldy Village. Don't underestimate the climb. It is a constant 12-mile hike to Sunset Peak with only a few flats and slight downhills along the way. It is a fire access and truck road. Most of the hike is exposed with a few shaded segments in the afternoon. Probably best left for a cool weather day or a very early start in the morning (5 AM). Very nice valley and mountain views. Came across one person in my 16-mile trek to Mt Baldy Village. Began at 5:30 PM and got to Mt Baldy Village at 10:20 PM at a fast pace. Plan accordingly as there is no cell phone reception for most of the top 4 miles.

We did not complete this trail fully as our dog ended up hurting his paw so we went about 5.5 miles in. This hike had a gradual incline overall with views of the Angeles mountain range and of Los Angeles city, it was a fire road almost the entire time. Not a ton of shade on this hike

The trail is unmarked, so I only found the trailhead from reading another review (it's behind the cement barrier). Once you find it, it's a steady incline from there on out. The views are beautiful. I ran 9.5 miles in one direction and saw on the map that I wasn't at the end of it, so I ran back down and finished in 19 miles instead of the 17.1 that this app says it is. I'd have to guess it's probably closer to around 21 miles there and back. It's a very secluded trail and I didn't pass by a single person in the 3.5 hours that I was on it. It was a very challenging run and I would love to do it again sometime. The only issue is that I got lost a little bit on the last 1.5 miles trying to find the turn that brought me down to my car because it was a small path that was unmarked.

Nice hike! Challenging hike!! First challenge is to find the trail head. Park right by the fence and the trail head is behind a cement barrier on the other side of the road. It starts narrow and steep. It gets wider after about 0.5 mile and keeps going up with a steady but manageable slope. Outstanding views. The best thing, and sometimes eerie, is the peace and quiet. I hiked 5 miles before heading down the link to Marshal Canyon trail and saw nobody! La Verne and Claremont are right below and yet feel so far away. Now as to the 0.3 mile “expert” link to Marshal Canyon/Cobalt Canyon trail—it is a butt kicker. First, it is almost a mile and not 0.3, and second it is steep and narrow with lots of loose rocks to walk on. I don’t recommend it for most day hikers, and i am sure not many hikers would even find it. Overall a challenging and enjoyable hike. Will do it again, going all the way and back.

Can get some nice views here in the winter when the air is clear. I've hiked the entire length of the trail from Glendora Ridge Road all the way down to the neighborhood at the end of Wheeler. Seen rattlesnakes, people on dirt bikes, bowhunters, and once thought I saw a mountain lion, but it was dark and the possible mountain lion was quick. Scary. Too bad the fire trail by Marshall Canyon has now become private. Takes one more access point to this trail system away.

You go through a narrow trail first for a bit then it opens up to a nice wide trail. No shade so be prepared. Was nauseous when I finished 10 miles. Great wildflowers, great views and a good steady climb! Will definitely do more miles when it is not 90 degrees. I do Sunset Peak via ridge route off GMR so it would be fun to do this longer distance hike. Views off the peak are outstanding!

Not thrilling but a good workout.

Devin, the actual distance of this hike/run is 25 miles, not 17. You stopped about 4 miles short of the actual Sunset Peak. I've done it a few times, and that's what my GPS shows every time. And it's easy to confirm, because, if you take a look at the All Trails map and see where your red line ends, it's about 4 miles short of where you see Sunset Peak marked on the map. When you veered to the right near what you though was the peak, you should have stayed left and then cut up the trail the map map shows keeps going a lot farther. Take a look on the map at the trail that keeps on going well past where your line ends, and you'll find the words "Sunset Peak" and an X marking the spot that is the actual peak. You should try the hike again, the views from the real peak are worth it! :) By the way, I'll pull this review off of AllTrails soon so it doesn't appear to be a criticism. I'm just hoping you'll read this and correct the distance and show the entire route on the map so it doesn't mislead people. It's a nice trail and I've hoped someone would post it on AllTrails, so it's great to see you've called attention to it, but it's important to give the right information here.

Went on this trail a while back but thought it was super cool! It wasn't too bad. Has really nice views. It's kind of hard to find but if you you the other picture on here it's pretty easy. You just have to park right before the dam and you're pretty Much at the beginning of the trail. Just to warn you the trail kind of has a lot of bees going up so make sure you're covered well if you do this one. Definitely a good hike
