Hike Upper Arroyo Seco! 10 miles/Beg-Interm

Highlights: Forest shade, rock hopping, streamside trail, waterfall + deep canyons

Distance: 10 miles

Level: Beginner-Intermediate (moderate pace)

Time: ~5 hours

Elevation gain: 1400 ft

Trail: Out and back

Get outdoors. Get sweaty. Get spent...hiking w/friends!

Let’s go on one of the loveliest hikes in the San Gabriel Mountains! The hike is rugged, peaceful and mostly shady with oaks, spruce and alder (some parts exposed). We'll hop the stream several times, travel high above the 50 foot high Switzer falls and head towards Oakwilde Campground, where we’ll take a good rest before heading back the same way.


sunblock, snacks and 2 to 3 liters water + 10 hiking essentials

NOTE: PLEASE carry MINIMUM 2 liters (4 bottles of water). After 10 miles, 5 hours and a fair amount of elevation gain, you will need it!

No bathrooms at trailhead. Restrooms at 2 campgrounds along trail.
