I belong to a family boating/Camping club on Lake Allatoona, and we have about 3 spots for new members right now.
We have running water, mens and ladies room, a pavilion, and very large amount of docks.
We have a section for tent Camping right on the water, and about 3 spots for popup campers or what ever type you have needs to be less then 18 feet ruffly.
The site is located off Hwy 75, the Allatoona/Emerson Exit, or by boat then its south of the Dam, about 10 min ride.
This place is the cheapest deal on the lake.
If you are interested, then ask me some questions and I will be happy to answer them. If this looks like a good fit for you and your family, then lets meet up and I can show you around.
