Noisy loud neighbors in cramped campsites
We were camping for 1 night and boy, was it crowded! Each and every group was fighting for the "wagons" to haul stuff up the hike-in campsites. Some groups even got aggressive with me and my husband for not "returning" the wagon to them. They even threatened and verbally abused us and a few other campers.
There was a large group of guys who had booked the campsite 29, and they were cooking biryani well beyond 1 am, and were drinking and running about noisily. Post midnight, a few campers asked those guys to keep it down but to no avail. The rangers are pretty much useless. When some of us filed a formal complaint with them, they didn't do anything about it.
Overall, this was a less than average experience. There's a reason that this campground so close to the Bay Area is popular with the larger groups. But best avoided.
