Look north from Los Angeles and you'll see mountains—real mountains, rising to over 10,000 feet. The San Gabriel Mountains form a dramatic backdrop to the LA basin, and they're remarkably accessible. Within an hour's drive, Angelenos can trade traffic for trail, smog for pines, and city noise for mountain silence.
The Angeles National Forest and surrounding wilderness areas contain hundreds of miles of trails, from easy canyon walks to demanding peak ascents. Whether you want a quick afternoon escape or a challenging all-day adventure, these mountains deliver.
Top Hikes
Mount Baldy (Mount San Antonio)
- Distance: 11.0 miles round trip (via Devil's Backbone)
- Elevation Gain: 3,900 feet
- Difficulty: Strenuous
The highest peak in the San Gabriels at 10,064 feet, Mount Baldy rewards with 360-degree views from an exposed summit. The Devil's Backbone traverse is thrilling but exposed—not for those with fear of heights. Ski lift option shortens the hike in summer.
Bridge to Nowhere
- Distance: 10.0 miles round trip

A classic LA hike following a ruined road to a surreal bridge spanning a wilderness canyon. Multiple stream crossings (wet feet guaranteed) add to the adventure. Bungee jumping from the bridge is popular.
