I have hiked this trail 5 times now, and I love it. I can make it up and back in 2 hours moving quick, 3 if I want to enjoy the walk. It can get really hot, so hike early. There's water and beautiful views at the top!

In the 1960's, we'd push our bicycles up the dirt road, camping the night at Henninger, then continue walking our bicycles to Mt Wilson, and make the big ride down Angeles Crest. I use to "live" at the Henninger Flats campground for weeks at a time, commuting by bicycle to job, while a college student.

Awesome hike, I've done this hike a few times now and will never get tired of the beautiful views, and the smells of all the wild flowers. Once you get to the top where the campgrounds are you feel at the top of the world its very peaceful and beautiful. All the times that we've been there we've camped and its by far best little get away from the busy city life.. I thank Enrique for introducing me to this great place. =|=

I was glad the first day was outcast made it colder. It was calve builder. Went to Idlehour and spelt the night. It was very green and plenty of water.

Be careful on the horsetrail section, saw two snakes today, one rattler (which slowly crossed in front of me), one garter snake (harmless). I patiently watched each one go where it wanted to go. Make sure to look ahead and watch your step. Very hot today, hiked from 10:30am-12:30pm. Not too many people. Saw some bikes, make sure to keep your ears open for the bikes coming downhill and always stay to one side or the other. Again, this is a great training, fitness, hike. No shade until you reach the flats. have fun.

The campgrounds are open now. Enjoy them before it gets too hot and the snakes come out. One of my favorite local hiking trail's.
