Switzer Falls

About Switzer Falls

Tucked into the folds of the San Gabriel Mountains within Angeles National Forest, Switzer Falls is one of Southern California's most rewarding natural escapes — and one of its lesser-known spots, despite sitting less than an hour from downtown Los Angeles. Fed by the cool, spring-fed current of the Upper Arroyo Seco River, the falls cascade in two tiers through a lush canyon corridor thick with alder, bay laurel, and oak. The sound of moving water greets you long before you arrive, and the air carries that rare mix of pine and wet stone that signals genuine wilderness.

The Landscape and the Hike

Getting to Switzer Falls is part of the experience. The moderate trail winds through the heart of Angeles National Forest, dropping into a shaded canyon where the terrain shifts from dusty chaparral to a riparian paradise. You'll cross the creek several times — expect wet feet, especially in spring — and navigate stretches of uneven rock and root. The two-tier waterfall system reveals itself gradually: first a lower cascade tumbling into a rocky pool, then the upper falls spilling down a sandstone face into a deeper, more secluded plunge pool. Lush vegetation crowds the canyon walls, and if you pause long enough, you may spot wildlife picking through the undergrowth. The whole scene feels improbably remote given its proximity to one of the largest cities in the country.

Swimming at Switzer Falls

This is an unofficial swimming destination, meaning you swim at your own risk — there are no lifeguards or safety staff on site. What you will find are natural pools fed directly by the Upper Arroyo Seco, cold and refreshing even on warm San Gabriel Valley afternoons. The lower pool is more accessible and shallower, making it popular with families and casual waders. The upper pool, reached by scrambling past the lower falls, offers a more dramatic setting and slightly deeper water suitable for jumping from the surrounding rocks. Water levels vary significantly with the season: spring and early summer bring the strongest flow and the most satisfying swims, while by late summer the falls can slow to a trickle. For the full experience — cascading water, vivid green canyon walls, and a crisp dip — aim for March through June.

Plan Your Visit

Switzer Falls sits within Angeles National Forest, and entry requires a valid Adventure Pass displayed on your vehicle — be sure to purchase one before you head up the canyon. Some passes are available at the Clear Creek Ranger Station along the way, but it's wise not to count on it. Picnic tables and toilets are available near the trailhead, making it a reasonable spot for a full day out. Note that camping is not permitted at the site itself. The nearest towns are Pasadena and Altadena, both offering plenty of options for a pre-hike breakfast or a post-swim meal. Wear sturdy footwear with grip — trail runners or hiking shoes are strongly recommended over sandals. Fall visits between September and November bring cooler temperatures and noticeably thinner crowds, offering a quieter version of this beloved canyon retreat.
