I've camped here twice, once with a small group of friends in tents for a weekend in late October around Halloween, and once on a snowy December weekend in an RV. Facilities are nice, sites were a decent size and I liked that they were pretty well wooded and so somewhat private. During the October trip there were a lot of families with kids, and it was cool because people decorated their sites for Halloween. During the December trip there really weren't many other campers at all, which was nice, but there were a few people with poorly mannered off-leash dogs, which was frustrating for us and our dog.
There's lots to see around the campground. There's a short walk to a pier that takes you to the water where you can get some great photos of the landscape and some wildlife; various nature trails to hike; and we also went to the Point Lookout Lighthouse. There are also some Confederate/Civil War sites but we skipped those. There's a park store at 10560 Point Lookout Rd on the way to/from the Lighthouse which has toiletries and other necessities you may have forgotten, plus snacks and drinks.
Michaux State Forest campgrounds have vault toilets and the sites are well-maintained. I went in late fall and was the only camper at the area I stayed in. Unfortunately you cannot reserve sites online and it's a little tricky, but it's free…
Camping is free in several areas throughout Michaux State Forest (as well as other PA State Forests), BUT you usually need to have a camping permit (also free) and you can only stay in designated campsites. To obtain a permit, find out where the designated sites are, and/or find out what designated campsites are available, you have to contact the State Forest District Office for the forest you would like to camp in.

I camped here 20+ years ago when I (a city girl) had just started camping and I still think about how awesome this place was. One day I'll definitely get back here. It was very secluded, quiet, and well-maintained. We had fun exploring around the campground climbing the boulders, and there were tons of trails nearby, plus overlooks with beautiful views. This place helped inspire my love of camping and being outdoors.
