Highlights
- Mount San Antonio, also known as Mount Baldy, is the highest peak in the San Gabriel Mountains, and the highest point in Los Angeles County.
- Mount San Antonio's sometimes snow-capped peaks are visible on clear days and dominate the view of the Los Angeles skyline.
- Also called Mount Baldy because of, as you can guess, its bald, treeless summit.
- Currently home to the Mount Baldy Ski Lifts, the closest ski resort to Los Angeles.
- Hiking trails access the summit from 3 sides of the mountain. The "Baldy Bowl" is popular with mountaineers; sections of the Bowl are steep with slopes of 45° to 50°.

"I started at 8 am at Manker Flats. I hiked on the paved road till it turned into gravel. I followed the gravel part up to Baldy Notch. There I found some snow but not a lot. I crossed a bit of snow to get to the start of the Devil's Backbone Trail. The snow was getting thicker the farther I went. I climbed Mt Harwood on the way to Baldy because I chose the wrong route. I took the switchbacks to the summit of Baldy. There was a ton of people on the summit. I hiked down the Ski Hut/ Baldy Bowl Tr. The pines were getting thicker the farther I went down.

"Great hike for number 17 of round two of the 2020 SoCal Six (18) Pack of Peaks Challenge. Started in Baldy Village and hiked up the Bear Canyon Trail to the summit and back. About 6.5 miles one way with 5433 in total elevation gain." — Philip-Yoho • Aug 22, 2020

"May 30, 2020. Parked across from the Baldy Trout Ponds and hiked up the Bear Canyon Trail to Mount Baldy, then took Devils Backbone Trail over to the Three T’s Trail. Summit all three T’s and came down Ice House Canyon. Hiked back down the road to my car. Very windy, over 50 mph winds on the exposed parts of the trails, even though the mountain weather forecast was only 20 mph. 21.8 miles and 8,035 feet of elevation gain. 10 hours and 51 minutes on the trail.

"Finally able to get back to the mountains during COVID. No snow on the trail, lots of little bugs to fly around your face, not too many people for a weekday hike, worth starting earlier to beat the heat. It's a tough push to the summit after being at sea level for months." — kerryscott • May 27, 2020

"Peak #13 of the 2020 SoCal Six (18) Pack of peaks Challenge and my 3rd peak of the Six Original Peaks. There was still snow on the mountain and I wasn't sure what gear I'd need, so I brought it all. Microspikes, Boots, Crampons, Axe and Helmet, Turned out I was able to easily summit with just the microspikes. I went up and down via the Ski Hut Trail." — Philip-Yoho • Feb 28, 2020

"Started at Manker Flat and hiked up the Baldy Bowl/Ski Hut Trail. After the ski hut, I mountaineered up the left side of the bowl (away from the rocks) and connected back onto the main trail to the summit. Then took the main trail all the way down. I used microspikes and my hiking pole. I did not need my snowshoes and had to remove my microspikes at one point as they were collecting snow and making me slide. " — runningvegan • Jan 25, 2020

"Mount Baldy once again from the Bear Canyon Trail in Baldy Village. I believe I did this one as a solo hike, out and back. So about 13 miles total with about 6,000 feet in gain and loss." — Philip-Yoho • Oct 5, 2019

"My fourth year support the Heroes Project as they raise money for our disabled Veterans to provide outdoor opportunities and fitness programs for our heroes. As a Veteran myself, I am forever grateful for and humbled by the sacrifices these men and women of our armed forces made for us. Semper Fi my Brothers and Sisters." — Philip-Yoho • Jun 23, 2019

"The Baldy Bowl/Ski Hit Trail was really nice. Steep climb, but a great workout with pretty views. I did West Baldy before heading down Devils Backbone. I was fine, but if you are afraid of heights then that trail is not for you. Did not care for the long section of road that I hiked down. Next time I would do Bear Canyon Trail to Baldy and take the ski lift down to avoid the road or do Register Ridge down. 12 miles and 4,000 feet of elevation gain and loss. June 15, 2019. A little snow on the trail to West Baldy, but no snow gear was needed." — runningvegan • Jun 15, 2019

"First technical winter climb up Baldy Bowl in mind blowingly gorgeous weather with forever views. Hooked.
Powder up to waist high from the previous day's storm made for a hard slog up what I think was GIrly Man Chute of Hourglass.
