This is the best free campground in southern California for the winter months in our opinion. Great views and it's nicely situated up in the hills away from everything else and had good cell reception. Nice and quiet, only saw about 6 other campers the whole week we stayed here in February. Only has pit toilets but hey, you get what you pay for haha!
Can get a bit dry and dusty at times so be prepared for that. Also there is no water in or near the campground so bring plenty of your own!
