13 Best San Gabriel Mountain Hikes
Mount San Antonio (Mount Baldy)
🥾 Difficult | 📍 Google Maps | Website | Elevation: 10,064 feet | Miles: 8
Mount San Antonio, also known as Mount Baldy, is the highest peak in Los Angeles County and one of the hardest hikes near Los Angeles. There are several ways to reach the summit but the Ski Hut/Baldy Bowl Trail is the most frequented.
The Ski Hut Trail starts at the Manker Flats Trailhead at the top of Mt. Baldy Road. It climbs 4,000 feet of gain in 4 miles and will give you a calf-burning workout.
You can also summit Mt. Baldy via Register Ridge, a steep 3-mile trail to the summit that is deemed the hardest way to the top. Bear Canyon is another trail to the Baldy summit that starts in the Mount Baldy Village and has 6,000 feet of gain in 6 miles.
Be on the lookout for bighorn sheep, mule deer, black bears, and bobcats that inhabit the area.
Cucamonga Peak
🥾 Moderate | 📍 Google Maps | Website | Elevation: 8,862 feet | Miles: 12
Cucamonga Peak is located in the Cucamonga Wilderness area and is a good hike for those wanting to rack up more trail miles. Get to the Ice House Canyon Trailhead early because this hike will likely take 6-8 hours.
The Cucamonga Peak trail winds through low-elevation switchbacks alongside waterfalls and pools. After the 3.6-mile saddle, the trail splits off to 5 different peaks, Cucamonga Peak being the highest.
The peak offers spectacular views of the Inland Empire and you can even see as far as Los Angeles on a clear day. Camping on the summit is a fun adventure and the perfect way to catch a high-elevation sunrise as it crests the skyline.
Ontario Peak
🥾 Moderate | 📍 Google Maps | Website | Elevation: 8,694 feet | Miles: 14
Ontario Peak is one of my favorite hikes in the San Gabriel Mountains. The early morning summit views of fluffy cloud layers covering the Inland Empire never disappoint.
Ontario Peak is a moderate hike and has far fewer crowds than Mt. Baldy and Cucamonga Peak. After the Ice House Canyon saddle, make sure to keep right at the trail split. Otherwise, you may end up on Timber Mountain.
Camp at Kelly Campground to make your experience last as long as possible. You will want to bring a bear box if you do camp on the mountain to ensure your safety. Make sure you also bring plenty of water (I usually opt for a water bladder) on longer hikes like Ontario Peak.
Pine Mountain
🥾 Difficult | 📍 Google Maps | Website | Elevation: 9,649 feet | Miles: 12
Hikers approach Pine Mountain one of two ways. The easier and hassle-free route from Blue Ridge Road in Wrightwood is the most popular way to hike this mountain.
More experienced hikers add on a Pine Mountain traverse after they have summited both Mount Baldy and Dawson Peak. Be prepared for a long day out in the woods if you choose to hike the mountain from this side. And start hiking early to avoid the summer heat.
Dawson Peak
🥾 Moderate | 📍 Google Maps | Website | Elevation: 9,575 | Miles: 10.4
Dawson Peak is the perfect mountain to hike if you want to be away from the crowds. The trail is accessible from Mt. Baldy and is shared by the Angeles National Forest and the San Bernardino National Forest.
The trail is also accessible from Wrightwood via the Acorn Trail and the North Backbone Trail. It is 10.4 miles from this side but not as steep as the Mt. Baldy side.
Park at the Manker Flats trailhead and hike to the summit of Mount San Antonio if you choose to hike from the Mt. Baldy side. After, you will follow a small use trail down the north side of Mt. Baldy to a deep saddle, then start the ascent up to Dawson Peak.
👉 Pro Tip: The descent from the Mt. Baldy summit to the Dawson Peak saddle is very steep. I recommend bringing sturdy hiking poles to prevent yourself from falling.
Mount Baden-Powell
🥾 Moderate | 📍 Google Maps | Website | Elevation: 9,407 | Miles: 8.3
Mount Baden-Powell is the highest mountain in Wrightwood and is one of the highest peaks in the San Gabriel Mountains. Take the Angeles Crest Highway to the Vincent Gap Trailhead to start this wooded forest trail.
Trail runners can finish this moderate trek in as little as 2 hours but plan on a 4 or 5-hour hike for a more comfortable experience. There are views of Mt. Baldy and the surrounding San Gabriels behind the iconic American flag on Mount Baden-Powell’s summit.
After your mountain climb, check out downtown Wrightwood. It’s a small California mountain town with cafes, a brewery, and two bars for a post-climb meal and drink.
Mount Harwood
🥾 Difficult | 📍 Google Maps | Elevation: 9,556 | Miles: 11
Mount Harwood is in the Angeles National Forest. Many hikers combine Mount Harwood with a Mt. Baldy summit because the trails are the same almost the whole way.
The easiest way to hike Mount Harwood is via the Devil’s Backbone trail to Mt. Baldy. Before the final Baldy climb, the trail splits off to the right to the Mount Harwood summit.
The summit will greet you with old remnants of a radio tower. There are often Nelson’s bighorn sheep on Mount Harwood’s summit, making this hike a favorite among many trekkers.
Timber Mountain
🥾 Moderate | 📍 Google Maps | Elevation: 8,307 feet | Miles: 9
Timber Mountain is the first of three summits on the Three T’s Trail. It is the easiest mountain hike out of the three and fun to do for a pleasant afternoon adventure.
Enjoy the cool mountain breeze and go for a dip in the lower-elevation pools at the end of your hike on a summer day. Timber Mountain is a peaceful hike with few crowds and abundant wildlife.
Telegraph Peak
🥾 Difficult | 📍 Google Maps | Website | Elevation: 8,985 feet | Miles: 11.4 out-and-back
Telegraph Peak is most often visited by hikers doing the Three T’s Trail.
Starting at Ice House Canyon following the San Gabriel River, the Telegraph Peak trail first takes hikers to the Timber Mountain summit. After Timber, hikers descend to a saddle and then climb back up to Telegraph Peak’s summit.
The views of the San Gabriels are incredible from the top. From here, you’ll have 360-degree views of the valley below.
Want to complete the Three T’s Trail circuit? Continue on the trail towards Thunder Mountain then down Mt. Baldy Road to Manker Flats.
👉 Pro Tip: The Ice House Canyon startpoint of the Three T’s is 3 miles down the road from the Manker Flats endpoint. Arrange transportation ahead of time or plan on walking on the road back to Ice House Canyon.
Iron Mountain
🥾 Difficult | 📍 Google Maps | Elevation: 8,009 | Miles: 12
Iron Mountain is known as the hardest hike in Southern California. It gains a grueling 6,000 feet of elevation in only 6 miles. Many hikers consider summiting this mountain a great feat that must be celebrated.
This hike will take first-timers up to 12 hours, so start around sunrise or before.
Because this hike is only 8,009 feet in elevation, it is accessible year-round and does not receive as much snow as taller surrounding mountains. I recommend checking out this hiking packing list before you go though, as you’ll need some gear.
Potato Mountain
🥾 Easy | 📍 Google Maps | Elevation: 3,422 feet | Miles: 5.2
Potato Mountain is one of the most popular hiking trails in the San Gabriels. Located in the Claremont Wilderness, the trailhead can be accessed from either Padua Road in Claremont or Mt. Baldy Road on the Upland side.
There are many trails to Potato Mountain’s summit. The favored way is a 2.5-mile trek via Mt. Baldy Road. Another trail starts at the same location but splits off to the left and climbs straight up 1,000 feet in less than 1 mile.
You can also reach the summit by the Claremont Loop. After 1-2 miles on the loop trail, keep a lookout for the Potato Mountain fork in the trail.
Per its name, you will find actual potatoes at the summit to take photos with. This is the best part of hiking Potato Mountain!
Rattlesnake Peak
🥾 Moderate | 📍 Google Maps | Elevation:5,826 | Miles: 10.1 miles
Rattlesnake Peak is a shorter mountain in the Angeles National Forest with a hard-to-find trail that will keep you alert. You’ll want to pack some reliable compasses to help you stay on the trail
Contrary to its name, the mountain is not crawling with rattlesnakes. Instead, it offers great views of neighboring San Gabriel Mountain peaks like Iron Mountain.
Rattlesnake Peak warms up quickly in the summer, so it is advisable to leave pets at home unless you have plenty of water for them.
Strawberry Peak
🥾 Moderate | 📍 Google Maps | Elevation: 6,167 | Miles: 7.2
Strawberry Peak is a moderate climb. You won’t feel exhausted on this hike and there are beautiful mountain flowers to pick along the trail.
The trail is exposed for most of the hike, so make sure to apply plenty of sunscreen and wear a protective sun hat, especially in the summer months.
Since the Strawberry Peak summit is only 3.6 miles one-way, it’s the perfect place to have a picnic.
San Gabriel Mountains Visiting Information
The San Gabriel Mountains are open year-round. You can hike at any time of the day, just make sure to bring a headlamp if you will be out after sunset.
An Adventure Pass is required to park in national forest trailhead parking lots. These can be purchased online here.
Have hiking questions? Contact the U.S. Forest Service or the nearest ranger station to your specific mountain hike. Many stations are open from sunrise to sunset to provide visitor information and issue hiking permits.
Tips for Visiting the San Gabriel Mountains
Get to Your Trailhead Early
Most trailheads fill up before 10 am during the summer so get to your hike early to snag a parking space.
Crowded hiking trails may make your hiking experience unpleasant, so I highly recommend starting early.
Find the Best Places to Cool Down
There are several places in the San Gabriels with watering holes and waterfalls. Mt. Wilson in the Angeles National Forest has a waterfall and swimming pool to cool down in after a long hike.
Bring along a Grayl Water Filtration Bottle to fill up with purified water on the go.
You can also escape the heat of the Mojave Desert by swimming in the Colorado River as it crosses the Pacific Crest Trail throughout the San Gabriel national forests.
Leave Wildlife Wild
The Angeles National Forest is crawling with wildlife. You might spot black bears, mountain lions, bobcats, mule deer, rabbits, and coyotes in the mountains and foothills.
While feeding or petting a wild animal may sound enticing, please always leave wildlife alone and only view them from a safe distance.
When to Visit the San Gabriel Mountains
The San Gabriels are fun to visit all year round, so you can plan to get out here during any California travel season.
The most popular time to hike is in the summer, although this Mojave Desert mountain range is fun to hike in the shoulder season as well. Choose the latter time if you prefer to hike with fewer crowds.
Higher elevation peaks like Mt. Baldy and Baden-Powell receive heavy snowfall in winter. You must have the required winter mountaineering gear if you want to hike these peaks during this time.
