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.

Someone broke into my car and took my spare headlamp from the glove compartment and tshirt & sandals I brought to change after the hike. Didn't have anything else valuable in the car but center console was wide open and ransacked. Came on a Thursday 11/2/17, there were only a handful of cars there and people on the trail. 5/5 in terms of strenuous climb (vertical gain per mile) for Whitney training but 2/5 for views/etc. Prefer other hikes in the 6 peaks challenge (Cucamonga, Jacinto, etc.) better.

The Devil's Backbone is way less scary than many make it out to be, there are only a couple of somewhat-exposed sections. Most of the hike I felt totally secure. The views here are great. If you're debating between something up the Icehouse Canyon or this, I'd choose this. The trail offers views the whole time.

I also recommend taking the lift down to save your knees--totally worth it.

Did this hiked alone from Manker Flat》Baldy Notch》Devil's Back Bone Trail》Mt. San Antonio》Baldy Bowl Trail》Back to Manker Flat. So I did a loop hiking this trails. It was better that way. It took me 3 hrs going down with lots of resting and pictures of the views. Stop by the ski hut too. It took me a little longer because I pulled a muscle of my right back knee and it was painful. So I slowed down. Going down from Baldy Bowl Trail was rough and steeps that's when I pulled a muscle because I slid down on my bottom trying to stop. Anyway, I hiked in the morning from 645am and back at my car 220pm with alot of resting. it's not bad at all. I stopped alot to appreciates all the scenery. This is not a race so take more time to rest.

Overall, strenuous, hard, very steeps trails. I had fun and a great experienced hiking it alone. Meet alot of people on the way up, at the summit and on the way down. Can't wait for next year.
