Many beautiful COE sites around the lake- no on-site sewer at any camp site, but dump stations. They are without a doubt some of the prettiest campsites in the south! I recall they do have a length of stay limit, but you can move to another COE campground or site-- if you can tolerate no sewer hook up. At the moment only R.Schaeffer Heard park is open near the dam, but the others are starting to open over the next month.
Pine Mountain RV resort has full hook ups and I think is the one of nicest private parks in the area. Its about 10 miles south of LaGrange on US 27 near Pine Mountain/Callaway Gardens. Also check out 3 Creeks Campground west of LaGrange for longer term stays.
Probably the closest in and nicest park is Highland Marina Resort. They allow longer term stays, are close in to town and are in a lovely setting on the lake

If you need to be west of town near the KIA complex, Southern Harbor Campground in Alabama across the dam on the west side of the lake is also a good private campground for longer term stays. Its nice but its a long ways out from LaGrange.
You may see reference to Hoofers Campground. They have a sign out front that they have shut down now.
Welcome to LaGrange. Feel free to drop a private message if we can give you more info!!
