This is the first of our Six Pack of Peaks ( series of challenging hikes up progressively higher mountains in Southern California. This is not a hike for beginners. Due to the pace, distance and elevation gain, it's intended for intermediate-advanced hikers. Know your limits!

Mount Wilson is one of the better known peaks in the San Gabriel Mountains, part of the Angeles National Forest in Los Angeles County, California. It is the location of the Mount Wilson Observatory and has become the astronomical center of Southern California with 60-inch (1,524 mm) and 100-inch (2,540 mm) telescopes, and 60-foot (18.3 m) and 150-foot (45.7 m) tall solar towers. The summit is at 5,710 feet (1,740 m).

We will be hiking a ~14 mile loop that takes us up to the top of Mt. Wilson in the San Gabriel mountains, with a short detour to the popular Sturtevant Falls. From the falls, we'll take the Gabrielino trail to the top of Mt Wilson -- one of the best known peaks above LA with commanding views of the city -- then down the Winter trail back to Chantry Flats.
