This place is great, is close to LA (right off 101, exit Kanan Rd), but seems so far away, remote, like you're away on a trip. It reminds me of Cambria. Follow the signs off the freeway and you'll get there. You'll pass the ranch to get to the parking lot. Free (plenty) parking and you can visit the ranch for free, grab a map, explore the grounds.
You can take a hike on the trail. Or bring a picnic as others suggested, I did and it was great, we had a nice meal out, in the nature. There are various spots with picnic tables. There were other people around, but not too many, they kept it to themselves, it was nice and quiet. Very relaxing, you can bring a book. Sure, there are bikers passing by, but it didn't bother us.
Across there is a bar/gastro pub with an interesting menu and a wine store/art gallery that offers wine tasting. Cool places, it's worth checking out.
If you live in LA and like exploring it, this place is a find, a little gem, away from it all. Just a cool area that makes you feel like you're in a weekend gateway.
