Official description is pretty good. For non-campers, admission is $5 per car. Several flat loop trails, none of which are all that long, make for an easy family excursion. Trails can also be combined for around a 6 mile hike that winds through wooded and open marshy areas. There's plenty of shade along the trails and it was pretty still during our morning trip to the park, so there were pockets of mosquitos.
There's a small gift shop, nature center with taxidermy of local wildlife, ground sloth exhibit, which includes a fully assembled skeleton that looks down on viewers, and a small room with live reptiles.
The playground looked very nice too.
While there is a donation box in the main building, admission is free. Hours aren't listed on Roadtrippers so put them below. They have a snack bar, but the hours are pretty limited, selling lunch items, from 11AM-2PM.
My wife and I stopped here while travelling from Atlanta to Savannah. It's a bit of a detour but well worth the visit if you like aircraft and/or military history. In addition to several hangers filled with planes, there are many other interesting exhibits.
The picture on the listing isn't current as there is another large hanger to the left of the one in the back. This houses display aircraft as well the many they are working on restoring. We got to talk to a couple of retired gentleman that were working the restoration of a 50's era helicopter. They were very accommodating, explaining about the museum, where they get the planes, and current states of the various restorations.
Monday - Saturday 9:30am to 5:00pm
