Quiet, but a little cramped
I stayed here in two capacities: Once as a family camper and once with a scout group. Of the two, the scout camping was preferable in my opinion (but clearly not an option for most).
The public campsites are very much hit or miss. Our site was on an incline, so trying to find a level area to set up camp was a challenge. Other sites had large, flat spots, so you almost need to visit in advance to figure out which sites are best.
When we visited there were free pieces of kindling to help start your fire. Bigger pieces were available for purchase, but you had to tote them from the front of the loop to your campsite. Having a wagon or using your car is suggested.
Depending on how deep your campsite is, you can easily walk into the park and wander the many trails.
Signs are small and easy to miss, especially in the dark. I drove past the nature center (or whatever it is called) several times because it is not marked very clearly and this was during daylight hours. During the night or winter when it is dark early, seeing those tiny signs by the side of the road would be even more challenging.
Not a ton of frills here, but the price reflects that. Good for a getaway or cheap place to stay while visiting Gettysburg or Chambersburg.
