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 .
