I have taken my son camping here several times. Great small park. The big attraction here is the lake, which looks like something straight out of a Louisiana swamp movie. Huge old cypress trees with Spanish moss hanging from the limbs. The park rents canoes or there is a boat ramp to launch your own boat. The lake is very shallow and navigation can be tricky if you don't pay attention. I recommend a compass & getting the lake map from one of the bait shops near the park. With those, it's pretty straightforward. There are guided tours of the lake by vendors outside the park that are worthwhile. The nearby historic town of Jefferson is worth a visit also. Lots of history, Jefferson was a major supply point & gateway city to the West prior to the Civil War.
I have camped here multiple times with my son and a couple of other times with the Scout troop. If you have kids, the fort buildings are always a hit. They have restored the old hospital building & the officers' living quarters. Decent trail system for short or longer hikes. Usually not too crowded and campsites have decent spacing.
