Looking for quiet car-camping spot within two hours drive of NYC

First, http://www.reserveamerica.com/ a nice site that will show you most of the camping spots in the area. I'm a big fan of the Catskill mountain range, and would recommend almost any in the area. I would suggest going to http://www.reserveamerica.com/camping/North_South_Lake_Campground/r/campgroundDetails.do?contractCode=NY&parkId=5&topTabIndex=CampingSpot right outside of Hunter Mtn. It's quiet, offers a bunch of hiking and biking plus amazing views and some killer waterfalls. Also, if you end up getting rained on, the village of Tannersville is 15minutes down the road and offers some nice cafes/restaurants to spend the afternoon. (check out Last Chance Cheese, it's worth it). Have fun.

If that's too far, also look around the New Paltz area. Also in the Catskills, but will be 30-45mins less driving and also offering a good amount of non-camping options if needed.

Thanks for the answers. It's funny, I asked my Dad this morning where we used to go camping when I was a kid, and he said, "High Point, in NJ. It's the best." So I suppose nj_subgenius deserves some credit. We ended up bailing on renting a car ($120/day!) and decided to camp via public transit instead. For anyone looking to get away from NYC, http://maloufsmountain.com/ is a pretty nice spot. It's located in Beacon, NY and they'll pick you up at the train station. It's a hike-in campground (anywhere from 30 minutes to 5 hours, depending on your interest) and they carry your gear to your campsite via ATV and will provide food and/or tent for an extra fee. All the sites are pretty isolated. Maybe it was the time of year (early October) or the rainy weather, but we couldn't see or hear anyone from our campsite. We had a platform site with a covered tarp, so the weather wasn't a factor. While they do a great job of getting you set up, they're strangely a bit less helpful in getting you out. They ask that you cart your gear down to a common area when leaving, which is quite a hassle when your campsite is several hundred yards away. It was also puzzling, since they seemed to be making rounds on an ATV the previous day almost on the hour, and a gear pickup seems in line with the gear dropoff. They also apparently don't drop you off right at the train station but at a nearby restaurant. We packed heavy since we were under the impression that they do full pickup/dropoff, and the fact that they were less accomodating on the way out than on the way in was a bit disappointing. Overall, I would recommend them, with the caveat that you pack light, or at least have decent backpacks for carrying your gear.
