Great moderate hike full of history! Very popular trail, so get there early. And pay attention to the street signs! There are a few "No Parking Anytime" spots and I always see cars with citations parked in them.
Bring a lunch and enjoy the ruins of what once was an LA getaway. Or, extend your hike up to Inspiration Point making this a double digit hike!

It's a neat trail, decent view of the city and DTLA. Constant climb to the top, easy downhill on the way back. Deff a moderate-difficulty trail. Was pretty, but just not nature-y enough for me personally. I prefer Eaton Canyon any day.

Sooooooo many people 8am Sunday morning. Was constantly dodging and weaving.. also is a very narrow trail. Barely wide enough for me and my dog which made constantly having to pass people frustrating... I'm sure there's a better time to visit. There was a neat little look-out point with old railroad gear and stuff at the top. Historical spot.

TLDR:
Narrow, extremely busy. Uphill climb, downhill descent. Worth doing once. Neat views of the Valley and DTLA in the distance.
