The Mt Hillyer Trail hike takes you on a mellow summit loop through a little-hiked area of Angeles National Forest. The climb isn't tough, the distance isn't extreme, and that's part of why it's great. You'll hike through the old stomping ground of 1860s horse bandits, complete with a hidden pasture and boulder hideout. And at the summit of Mt Hillyer, you're rewarded with sweeping views of the eastern San Gabriels. Oh, and there are two different summits with two different views. So you got that going for you, which is nice.
The Mt Hillyer hike trailhead can be confusing; other guides have a variety of starting points. This guide follows one of the more traditional routes for the hike, and you don't have to worry about washed out roads or high-clearance vehicles. As long as Angeles Crest Highway is open, you should be able to get here.
There's not a good physical address for the trailhead, so follow these instructions instead.
You need to display your Parks Pass or Adventure Pass to park here.
Gear For the Hike
Overall the hike is fairly exposed, so you should use sun protection and bring at least 1L of water (I bring 2L). And bugs can be around; plan accordingly.
Nothing is sponsored or promoted, just the actual gear that I use.
Garmin InReach Mini 2Hit SOS or just tell loved ones that you're running late where your cell phone has no service. Review here.
Topo MTN RacerAggressive and fun with a wide toe box (=no blisters). Get them wet, they dry quickly. Lots of cushion and comfort.
Osprey Hikelite 26Lightweight, carries all your gear, and your back doesn't get sweaty. Oh yea, it's also one of the most inexpensive packs you can get.
The trails are generally well marked and easy to follow. The climb through the boulders can be tricky; there are many small use trails to bouldering spots. I'll tell you what to look out for in the directions that follow.
Some GPX tracks and apps out there have this loop going in the opposite direction as I do. I find this (traditional) clockwise direction to be more enjoyable; it avoids doing the main ascent on a paved road. And if you want to avoid the pavement altogether, just hike to the second peak, turn around, and go back the way you came.
Once you dive into the map, you might notice that the official summit marked by the USGS is not the highest point, which is the higher ridgeline to the southwest (6200 ft). The Sierra Club has been using the higher 6,200 point as the summit since 1946. In this guide I'll take you to both spots; each summit offers unique views and is worth a visit.

Hike Brief
This hike goes through the hideout area of Tiburcio Vasquez (1835-1875), the bandit who the character Zorro is loosely based on. The hidden pasture at Horse Flat Campground is where the bandits would keep their stolen horses, and the boulders of Mt Hillyer offered a fortress that they could retreat to if discovered. Vasquez was caught and hung in Runyon Canyon.
The peak is named after Mary Hillyer, a beloved clerk who worked for the Forest Service in the 1920s.
The loop is popular with mountain bikers, so keep an eye out. The tire tracks can come in handy. If you are in doubt of which trail to take, follow the bike tracks.
