This is in Old Topanga Canyon. There are a few trails leading there, so you can take one up, and another down. The last 300 or so feet is off the trail to keep it hidden from Joe NormalHikerGuy... See the spoiler info below for a hint on where to start and the final find. I've got a dollar riding on Wolf & Ingrid being the first to reach it...
I recommend parking at N 34 06.368, W 118 38.224, though you can certainly park a little further back, where the dirt road starts.
I had a lot of fun with this. DahMooser and Ms. Pea came along for the ride but hung out about half way up the hill so they could find the cache themselves. I still think the Sr. Hikers will beat them...
Have fun! Oh, yeah, bring a bottle of water in case you get thirsty.
* NOTE: Apparently someone took it upon themselves to move the cache a little, so until I get up there to move it back, please ignore clue #2
