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.

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.

Great winter/spring hike in cooler weather.

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.

Great trail with campsite to test out new gear. There's a soda machine in the museum / sign in (If staying overnight, just ring the doorbell to have the attendant come down to give you a fire permit). There's usually scouts at the camp but I haven't had a problem finding a spot to setup my hammock. I usually camp at the upper camp and the last time I was there, there was a homeless squatter in a red tent.

Not a hike as much as a switchback fire road. Go in the early morning since there is no tree coverage until the end. If you have them, bring your hiking poles. Pretty views of the city and a couple lookout points with benches.

Meh, It's a fire road with no shade (go early, when it's cool or overcast) and views of the city. Not really a proper "hike" but a great workout since it's straight up.

This is a short but all up hill hike along a dirt road. It's not very scenic other than views above the city. This is a good hike for a work out. Or a quick easy backpack trip or test out new gear or learn how to backpack. Go early in the morning or late afternoon because during the peak of the day is no shade and it gets HOT!

At Henniger Flats there are campsites for free. Check in with ranger.

Bring water! There is NO WATER along trail or up at campgrounds.

Park on neighboring streets make sure to read parking signs.

Not sure sure how hiking up a fire road to a well-manicured campground, equivalent to that of a car-camping site, can really be called "backpacking." There are people that love California sushi rolls, too.

This hike offers a great workout with a steady 3 mile climb on a wide, well groomed, highly trafficked gravel path. The incline makes this a moderately difficult hike, but the path itself is suitable for all. The hike offers great views that overlook Pasadena and beyond and hikers can enjoy a snack or even overnight tent camping at the top (Henninger Flats). The top is well shaded and there are a few historical monuments at the top to explore before heading back down the hill. Proximity to Pasadena, ease of parking, and the great workout factor make this hike one to enjoy repeatedly. If I didn't live nearby, I might opt for other, more technical or less traveled paths to enjoy as this one is well used by locals. Reminder: Go early on hot days and don't park on Pinecrest...they were ticketing today!!

There is plenty of street parking for overnight backpacking. Took about 1 hour to hike the trail up from the TH to the campgrounds. I stayed in the lower campground as the city views were PHENOMENAL from there, and I was backpacking solo (the upper levels were more for camping groups and people that wanted to feel isolated). There is a ranger on site 24 hrs/day, and they also give free firewood. Also, there is a basic toilet, and water from a faucet out of the ground, but I packed in most of my water anyway. The only caveat for this site is to NOT HIKE UP when the temperatures are high, as there is literally zero shade the entire 3 miles up the rather steep fire road. Not fun at all when you are lugging a backpack and a gallon of water into camp.

This one was a great workout. Total incline, be prepared. Go early as it gets got and almost no shade until you get to the top.

It was a great hike all up hill. Great workout. When you reach the top it's like your walking into another dimension. The waterfall was nice but too crowded, go early and beat the crowd.

This was a great hike! At times it seemed never ending, but it is a very rewarding hike. Our two labs were so exhausted afterwards....love it!!

It's been about 3 decades since I've been up to the flats , My greatest memories of being up there was when I was in elementary school. A teacher by the name of David Osborne use to take us kids hiking up the trails (Group of 20 or so) .We would get up to the flats have lunch and then have a few games of capture the flag ...
Mr. Osborne died of cancer when I was about 10 years old I'm 41 now ....

I'm planning on a hike up there real soon just to take a day to remember a great Teacher,coach and friend !

Thanks for the memories!
