My girls (13 and 10) and I spent two nights camping at Kolomoki. We found a great spot near the lake; unlike some other state park campgrounds that we've been to, this one was quiet. Being near the lake, we expected to have to deal with lots of bugs, but we only had ants (oh, the ants got into everything!).
We enjoyed swimming at the lake, though the "No swimming, alligators present" sign just past the swimming area was a little worrisome. The museum is excellent and the mounds were fascinating as well. A bit off the beaten track, but a lovely place to go camping.
We had so much fun hiking the state park at the Kolomoki Indian Mounds. This state park is part of the Georgia State Parks system and provides visitors an opportunity to hike around and over ancient Indian Mounds.
I advise lots of portable drinks and long pants no matter the weather. The hiking trails are not appropriate for strollers. Carrying small children in back or front carriers is best at this park.
Despite the climb up the hundred+ steps, the view from the top of the great mound is beautiful!!
