Getting There

As of September 2020, trails in this area are closed due to wildfire. See park page for more information. A strenuous loop to the 10,068' summit of Baldy. Any Southern Californian can point out the white topped Mt. Baldy - actually it's real name is Mt. San Antonio. Baldy is a SoCal icon that stands out boldly as a snow-covered backdrop for much of the year. At 10,068 feet above sea level, the snow often sticks around well into June. This loop begins at the Manker Flats trailhead (National Parks Adventure Pass required), taking the winding fire road up Baldy Notch, then hiking the Devil's Backbone to the summit. The return route takes you down via the steep Baldy Bowl trail, passing the Sierra Club Ski Hut and San Antonio Falls on the way back to Manker Flats. This is the third of six southern California summits in the 6-Pack of Peaks bundle. Done in sequence, they provide great training anyone preparing for bigger hikes such as Mt. Whitney or Half Dome. Each hike in the 6-Pack is progressively higher in altitude, and all have respectable distance and vertical elevation gain. When you're at Baldy Notch, there are several paths that head towards Mt. Baldy (none of the marked). DO NOT take the far left path. That will take you to the foot of the Turkeyshoot ski run. It may be the most direct, but your legs will never forgive you for going up that run. No matter how you get there, though, all of the trails take you to Devil's Backbone, which leads you to Baldy. It's not so bad before the final ascent, but there are places where both sides of the trail drop away, and you could get some vertigo, if you're prone to it. But the ascent is the real butt-kicker. When you round Mt. Harwood and head for Baldy, the rest of your path is brutal and relentless. The views at the top are incredible, and there's wind-breaks other folks have constructed out of stones, so you can take a breather behind one of those if it's too gusty. From there, you have your pick of ways down, either back the way you came, down the Baldy Bowl/Ski Hut trail, or the Bear Canyon trail. Good luck. Make sure to check when the ski lift closes, if you plan to take it back. NOTE: Be sure to park outside of the white line along the road. It can be difficult to see in the snow but the police will have you towed if parked incorrectly.

You will need a US Forest Service Adventure Pass to park at the San Antonio Falls parking area at Manker Flats, if you don't park at the ski lift.

California Travel and Tourism Commision, P.O. Box 1499 , Sacramento, CA, 95812-1499, Phone: 800-862-2543

Check with the Baldy Village ranger station (909-982-2829) for the latest conditions. Avoid hiking the Devil's Backbone or Baldy Bowl trail when they are covered in snow, unless you are trained and equipped with crampons and ice axe. You can do this hike in reverse, for a strenuous, really steep climb up with a more gradual return. Over half of this trail is partially or fully-exposed to the sun. Be prepared with proper sun protection (wide-brimmed hat, sunscreen, etc.). No permits are required for day hikes on these trails. If snow is on the summit, bring crampons and an ice axe. Only attempt when there is snow if you have the training and experience. As always, bring your 10 essentials, plenty of food and water. This is not a pleasurably stroll through the woods, this is a strenuous day hike. Not for the out of shape or unprepared.

Directions from Claremont, CA: Drive up San Antonio Canyon to the Mt. Baldy ski lift. Ride the ski lift up to Baldy Notch, about 7,800 ft. elevation. The lift operates weekends and holidays year-round and daily when snow conditions warrant.

FYI. All trails in the Mt Baldy area (all of the Angeles National Forest) remain closed. Went up there today to potentially hike it but despite the USDA website indicating that the trail is open, sadly it is not.

Tuff hike. Started at Manker Flats at 8:40 am and made it to Mount Baldy at 2 pm. The way back down through Baldy Bowl is steep and dangerous. Made it back by 6 pm. Great work out but very strenuous. Take at least 4 liters of water, Gatorade, and snacks. Long journey but a great accomplishment. (Don't get lost) Several paths that take you to other locations. Be careful.

This trail was easy to find parking was available. I drove a lowered Scion TC and had no issues parking in the gravel. Definitely great views everywhere the trail is travelled a lot so its hard to get lost.

Trail was super hard for me but it was amazing! We went up Devils Backbone and came down Baldy Bowl. The way down is super steep no matter where u choose, but I’m glad we decided to do the loop. I brought 4 liters water + 32oz Gatorade. BRING FOOD YOUR BODY WILL WANT IT! I have asthma, and the altitude definitely affected it, just a head up for anyone. Also got a little bit of altitude sickness but oh well lol. No complaints about the trail or anything like that

Trail was in expected shape, no real problems beyond the usual grueling exertion it's known for! Popular spot today with ample foot traffic heading both ways.

Great Hike ! Mt Baldy trail up and back is very challenging. It final 3 steep incline up towards the summit is really difficult. Recommend take your time and not rush. It’s a kicker. Started at Mt. San Antonio Trailhead 07:30 return safely 15:15. Beautiful day!

HikingGreat!Rocky

8/25/20 Started the trail around 6am and finished around 1:30pm with a big 45min break at the summit and few rest stops along the way to the summit. Hiked the trail clockwise and turned out to be worth it because it was easier on the knees, however it’s a steep incline going to the summit. Parking is free along the side of the road. Started off with 3L of water and drank about 2L alongside with trail mix. The weather was pretty good the highest it was around 85 degrees but this was like the last few miles of the looped trail. The summit is windy and exposed. I recommend bringing a hat on this hike. Another plus, there were very few bugs. This hike is fantastic with a waterfall right at the beginning of the trail and panoramic views of the different peaks surrounding the Cucamonga wilderness. I was lucky because the horizon was extremely clear and filled with plenty of breathtaking views. One of my top trails no doubt.

Got to the trailhead at 730 am on a Saturday and it was packed, not much parking left. Did the route counter clockwise. First part of the hike up until the ski lodge is deceptive since it’s relatively moderate. Right after the ski lodge there’s a pretty steep section. Overall the hike wasn’t crowded but the summit was, I imagine this is because there’s several ways to get to the top. Saw folks at the summit from the age of 8 to 60+. Came back down via Baldy bowl which is quite steep and can be pretty hard on the knees if you have knee problems.

Wow probably one of the most beautiful trails Ive done definitely would do it again! Went on a Saturday around 10:30 parking was hard to find finished around 4. 360 degree views at times absolutely breathtaking! last steep climb to the top is super crowded and super steep but if you pace yourself its not bad. Feels like your on top of the world at the top. Partly shady partly sunny. Loved this hike so much!
