In the Lower Suwannee National Wildlife Refuge, this is a fairly remote campground away from everything. There are about 28 or so sites, with varying degrees of amenities (three sites are tent only with no hook ups, some sites have electric only, and some both electric and water). Cost depends on amenities: the tent only sites are going to be $10 a night in 2020 (it was only $5 a night for me this December), and sites with electric and water are $15. There was a dump station for RVer's as well. Bathhouse was clean if dated, with a fairly new shower stall.
The sites on the inside of the loop are all on a slope and have the playground, office, and bathhouse as the hub. The outside of the loop sites all back up to woods or marsh. I was in tent site #9, which was right next to the marsh. It rained overnight and I noticed the site could flood if it had rained a lot. But my other option was next to some well established and loud RVer's next to the playground, and on a slope. I chose the flatter site next to the marsh, but I think that wasn't much better as it put me right in with the mosquitos and no see-ums. Bring your industrial strength bug spray!!
The campground is next to an arm of the Lower Suwannee National Wildlife Refuge and so it's close to a few nice trails and a nice boardwalk and fishing pier. If you need ice or firewood or some basic groceries, head back out the way you came in and stop at tiny little Ms Dot's Grocery. She is super nice, has lots of knowledge of the area, and her ice (BIG cubes) is super cheap.
