We just traveled through your area and found a really nice state park about 8 miles north of Lake City. The Stephen Foster Folk Culture Center State Park.
We only stayed one night, but the entire park was great and super relaxing place to be.
In December they have a big drive-thru Christmas thing and there were signs of them getting ready for that already. But, I recommend that State Park to anyone nearby.
We use RV Park Reviews - Trusted Reviews of Campgrounds & RV Parks
to evaluate places we think we're going to stay at and on a 1 to 10 scale this state park has a 9.1 rating. Which is super high for a park with a lot of reviews.
By the way, the guy that owns this website also owns rvparkreviews.com.
