San Gabriel Mountains

Oftentimes, pictures of Pasadena show beautiful mountains in the background, those are the San Gabriel Mountains. The San Gabriels are part of the Angeles National Forest, which was formed in 1908 by combining the San Gabriel, San Bernardino and (at the time) Santa Barbara Mountain reserves—it was the first National Forest ever established in the United States. They seem a lot smaller in photos, it requires seeing them in person to realize that one-thousand square miles (1,600 km) make up the vast mountain range, it has several peaks, trails, campgrounds, villages where people live and work, an observatory, ski lifts and a zip line course.

Travel Responsibly

Before you go, please familiarize yourself with local guidelines and tips so you can enjoy your stay safely and responsibly. We also suggest reading and following the California Responsible Travel Code to ensure that the Golden State remains a beautiful and viable destination over the long haul.


There are several great trails, skill levels range from moderate to very difficult. A few highlights include Throop Peak which is incredibly scenic, Switzer Falls which leads to a waterfall, and Bridge to Nowhere trail that got its name from a bridge that was left unfinished after a flood.

California Historic Landmark

Mount Wilson Observatory

The inversion layer over Los Angeles creates more natural steady air over Mount Wilson than any other location in North America, making it ideal for astronomy and in particular for interferometry. The observatory's Hooker telescope is one of the most famous telescopes in observational astronomy of the 20th century. It was used by Edwin Hubble to prove that the Universe goes beyond the Milky Way galaxy and showed that it was expanding. The discoveries made with the Hooker telescope fundamentally changed the scientific view of the Universe.
