Castle Rock car camping beta

I'm in the bay area on business and was hoping to get some climbing in at Castle Rock, but today when I went to camp there I was told the only sites were a 3 mile hike in! Damn, thts my fault for not planning ahead but surely there's other camping nearby where I could sleep in my van, nope, at least not according to the rangers. All the camp areas nearby were either full or don't allow you to sleep in your car.

I need a place to sleep tomorrow night, preferably in my van, I didn't bring a tent, so that I can climb at Castle Rock all day Sunday before heading back to Los Angeles.

Does anyone have any good beta on places/camp sites/back alleys where I could sleep in my van for the night in relative safety???

Any help would be greatly appreciated, thanks!

Ha Cole your so screwed...... nobody uses MP in the bay area... Super Topo might have done the trick.

GK

Wait I do. Am I the only one here? I hate super topo and rockclimbing.com.
There's just no good car camping near CRSP. Is there? I usally hike in 2.8 miles to the campground. Dont be a woose its not that bad.
