Lovely place if you have a good site
We had a great weekend camping trip at Coe Ranch - thanks to being at one of the sites with a bit of shelter and shade. Beware that many of the sites have neither of these things, and can be really exposed.
I’d recommend sites 10-12, 13 looked ok - and sounds like other folk recommend the ones down the hill a bit.
