Most of the campsites are pull-through at Big Springs Campground. Site 1 is a good example.
Campsite #2.
Campsites 3 and 4.
The area near site 11 has some open areas.
Most campsites will have a picnic table, fire pit with attached grate, and a campstove stand.
Big Springs has a group site available for up to 40 people. Sorry, I don't have better pictures but it was occupied.
