We stayed at Crystal Lake campground on Friday the 13th! Luckily we arrived before 3pm as the campground was pretty full by 6pm. I give it 4 stars for being about 90min from Corona. However it is close to LA and there is still a lot of graffiti at the pit toilets and the group next to us was pretty rowdy all night. Sites are all pretty well shaded. Crystal Cafe sold firewood by the wheel barrel and only $20! I’m glad camp fires were allowed as the temperature dropped pretty quick once the sun went down.
