I've camped here on and off since 2015.  I feel like it's gotten better recently in terms of groups of loud partying people doing doughnuts in the parking lot at the entrance.  A few years ago we had a person literally stumble into our camp and almost fall into our fire… but I haven't had anything strange like that happen in the past year.  I believe the rangers have been cracking down on people in this area, which is very nice.  The views of the lake are breathtaking.  I've camped here 4 or 5 times in the past year and it was very quiet and peaceful.  There can be some traffic in the early morning due to people coming going down to the shoreline to fish, but it's not a terrible amount of noise.  My neighbors to my site were also nice.  

If you have dogs, beware of the coyotes.  There are a lot of them here.  Some are skittish and will run away from you, but some have lost their fear of people because people have been feeding them.  Keep your dog leashed at all times.
