Fire road, easy hikebike, nice views The hike to Henninger Flats is on a fire road with no shade. Therefore, hike very early during the summer. There are nice views of LA if you happen to hike after a rain storm or a windy day. Scenery is nice when you reach the Flat. There is a Nature center, a picnic area and public campground set amid trees.

This is a great training trail. It’s a complete grind and there’s little to no recovery stretches. Essentially you’re going up the entire time. Very little shade until you get to the top. Also little pee privacy if you are a girl. It’s a great workout and there’s very pretty views of the city going up the hill.

You are hiking on a service road the entire time until you get to a campground at the top. The campgrounds are really pretty and a nice place to relax after the hike up. Explore. Also you’ll run into a lot of mountain bikers.

The day I went hiking the fire department was actually maintaining the roads after the recent rain. The service road is comfortable to hike. I would recommend poles to keep your back straight going up and protect your knees going down. Other than that you don’t need them.

Alllllll uphill. But gradual—real butt kicker. But then allllll down hill from the flats. Lots of loose gravel and rocks on the fire road —so watch out.

Our new favorite trail. The stiffness was just right, not too stiff or to plat. Wide path, which gave you a safer feeling. People also bike here. And also, if you go down the path, you can reach the water. The view was amazing too. Especially with the bench.

this was a steady incline on a fire Road all the way to Henninger Flats if you measure it from the Eaton Canyon Nature Center parking lot it's 8.2 miles round trip if you park on the street you can cut almost two miles off of that some beautiful views from the top a lot of pine trees and solitude

This trail was nice and open! I liked the wide, dirt path all the way up, which was perfect for a conditioning hike. I recommend doing this hike in the morning on a hot day since there is no shade at all! The trail also wraps around the mountain a lot, you get a lot of different and beautiful views. I definitely recommend!

This my favorite place to go in the mornings :D
The way up can be a bit hard if you go midday. I would recommend doing this early in the day. Take a hat and some water because you will be in the sun for most of this hike. Once you reach the top you will have a beautiful city view. The top also has different places to camp, sit and relax. There’s currently no water up there. A hike you won’t regret <3

Only ran this once, several years ago during the government shutdown. It was eerie quiet with the campground not in use, and there were deer poking around. A steady up and a steady down, good for training for longer trail races.

We clocked in at 5.5 miles. We did it as a sunset hike. We started at 4:20 I think I would have started it at 3:30 so we get the sunset coming back down! You must park on the street there is no parking lot. To get to the top just cross the bridge and stay to the left this app have the correct downloaded road. Dogs are allowed on leash! It does get steep on some parts. There are three benches you pass on the way up. when you pass the Henninger Flats sign there are benches to the left. There is also a geological marker to the left of the sign of your staring at it. Bring a head lamp if your hiking it in the dark! Over all it’s a beautiful sunset hike!

Love this camp to just chill and cook. Great for hammocks and good views of town.

Great site for a beginner backpacking trip. There is no water at the campground, so come prepared. We hiked up at night with an almost full moon and did not need our flashlights until we arrived at the campground. Strongly recommend going up Friday night if you plan on camping, as you will get better campgrounds. Also, strongly recommend being dropped off and picked up, as parking is in a residential neighborhood and might be at a premium. No open fires on CG, but you can burn wood in the provided stoves.


Great views of the city below.

This is a great Hike for those who want to be on top of a Mountain. The incline is decent all the way. Has a nice nature Center at the Top along with 7 CampGrounds. This is the Beginning to the San Gabriel Mountains aka Sheep Mountain. Go Early! Avoid the Sun! It’s well worth it. You can see the ocean on Clear days

Awesome hike. Views of the campgrounds at the flats are gorgeous! Didn't realize how nice the view actually was until I started hiking down. Part of the Eaton Canyon trail. No shade, bring lots of water and sunblock!

Hiked mid-day in June and temps were high 80's. It was bearable for me, but a challenge. Had to stop a few times.

I loved it! Only hiked for 6 miles but it was worth it, mostly uphill so not for beginners, it’s great for building up stamina for more difficult hikes. I’d definitely recommend it.

Hmm...I only clock about 6 miles up to Henninger based on where I start I’m assuming. Not much scenery and no shade. If you want to build your tolerance of going up hill, I’d recommend this hike. Otherwise, there are other hikes that have a lot more going on (optically).

Straightforward. Check out the museum at the top and the fire lookout tower. I grew up doing this hike but it is no frills.

This was a steady climb uphill. No shade. There are two restrooms (outhouse style) with no running water. There is a water fountain but it doesn't work. You can set up camp for the night or grill in the charcoal pits. If you keep going, you'll eventually get to Mt. Wilson.

Great hike! But the dirt was slippery at times and I slipped and fell!

3 miles to lower campground
Another .2 to the upper

There is currently no water at the sites

Free firewood at Lower campground

At upper Campground, site 10 is the best and has views of LA

Slept in a hammock since there are a ton of trees

One of my new favorite places :)

The beginning is very crowded, due to its proximity to Eaton Canyon Waterfall. It clears up a little once you get on the fire road though. Though it's not an interesting hike (most of it is on a fire road), the views are incredible on a clear day. It's a decent option if you want to get some miles in but don't have time to go deeper into the Angeles National Forest where there's more interesting terrain and less people.

Fire road so not so exciting. Start early (before7:00am) to avoid crowd and dog haters.
