The Angeles National Forest, located in southern California, is one of the country’s best city escapes. Half of its nearly 700,000 acres cover the biodiverse San Gabriel Mountains, which tops out at 10,064-foot Mount Baldy. The forest encompasses two truly unique wildernesses: the San Gabriel and Sheep Mountain.

With 557 miles of hiking and equestrian trails, 176 miles of which are part of the Pacific Crest Trail; lakes and streams offering various water activities, and skiing and snowmobiling across its five ski areas, Angeles National Forest is an exciting year-round destination.

What is the History of the Angeles National Forest?

The Angeles National Forest has gone through many iterations over the course of its more than century-old history as protected habitat, starting in 1892 when President Benjamin Harrison signed an executive order establishing it as the San Gabriel Timberland Reserve.

Nearly a decade later, the reserve was transferred from the Department of the Interior to the Department of Agriculture. It was designated the Angeles National Forest in 1907, becoming the first National Forest in California. In 2010, President Barack Obama declared the San Gabriel Mountain Range a national monument, a site encircled by the National Forest.

Since the early 1900s, the population of Los Angeles has increased eight-fold. Today, the Angeles National Forest is one of the most popular recreation hubs in the country, hosting 3.5 to 4 million visitors annually—more than Montana’s Glacier National Park. The forest is also home to watersheds that supply 30 percent of L.A. County’s water and dams and debris basins that protect the city from destructive flooding.

Things to Do in the Angeles National Forest
Hike to the summit of Mount Baldy

There’s nothing like the sense of accomplishment in reaching the summit of Mount Baldy, the highest point in L.A. County at 10,064 feet. It’s reached via a popular but challenging 11-mile hike that features some 4,000 feet of climbing.

Visit Mount Wilson Observatory

Established in 1904 by astronomer George Ellery Hale, this historic observatory at Mount Wilson’s 5,710-foot summit is home to the telescope that Edwin Hubble used to learn that the Universe goes beyond the Milky Way. The observatory hosts docent-led walking tours every Saturday and Sunday at 11:30 am and 1 pm in the spring and summer.

Go downhill skiing

In addition to cross-country skiing and snowmobiling trails, the Angeles National Forest offers spectacular downhill skiing across three ski areas: Mt. Baldy, Mountain High, and Mt. Waterman. The most popular, Mt. Baldy Ski Resort has four lifts, a skiable area of 800 acres, and 26 runs that cater to all ski levels.
