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.

I've done this trail 3 times. I wouldn't say it's easy unless you're an avid hiker. it's mostly incline the entire way up with a few spots with benches to take a breather before continuing. the view from Henniger Flats is worth it though. people on the trail were friendly. it wasn't crowded (though the weekends could be a different story) but for sure go early in the morning to beat the heat!!!

It's a direct and wide trail to the campground. It was mainly incline all the way but very doable. The view up top was one of the nicest I've seen. It's quiet and takes you away from the city.

Basic out & back trail with consistently steep incline the whole way to Henniger Flats. Enjoyable hike with the cloudy skies today. Don't think I would want to do this hike in the blazing sun. Many nice people and dogs on the trail.

Fairly straight forward climb and descent. I like it as a training hike for a trip I'm planning. I like the wide path. There is no protection from the sun, so I go early. I've done the night Sierra Club hike, but prefer seeing where I'm going.

I hike this every other morning at 4:30AM for exercise. About 1 1/2 hours up and back.

6/30/15 - Finally got back into hiking after shoulder surgery! Started at 7:30pm to avoid the heat of the day. Trail traffic was light with about half a dozen each of hikers and mountain bikers. Since I was starting late I knew the gate on Pinecrest would be closed, so my exit point was through the fence gap off Altadena, before Eaton Canyon Nature Center, and then a short hike up the roadway back to the car at Pinecrest.. There were only a few sandy areas on incline so the trail grip was excellent! Ran into a beautiful rattlesnake crossing the trail at around half distance. It was about 2 1/2-3ft in length and never became aggressive, just was watching as we were. I noticed the Henninger Flat sign at the top is gone, but it made for a nice seating area to rest and overlook the city. The nearly full moon was fantastic and made for an awesome moonlit hike without needing to use the headlamp, and temperatures remained excellent with a nice light breeze for the hike down. If you are familiar with the trail and exit point after sunset it's an excellent summer evening choice!

Good trail. I don't know that I would call it easy, though. Moderate, but not easy.

Just one more point that a lot of people below are mixing the hike with eaton canyon hike, which are the same on the beginning but while henninger is all about inclination ,eaton is a very short , easy and leveled hike for the family.

Beautiful hike, take enough water and make sure you reach the top because it's worth it , could be done in 2 to 3 hours. Decent elevation .

easy overnight pack in, perfect to try out new gear or to get away even if its only overnight.
Camp spots have small fireplaces and camp provides firewood. When i went there was a posted sign that said Water ( from the spigot at the camping spots ) needed to be filtered or boiled prior to drinking.
