I really like this park for swimming in the Tennessee River. It is called Eva Beach. It is rocky, so be sure to bring proper footwear. They have a small sandy area and many shady picnic tables. There is also a huge open pavilion,(sadly usually claimed daily, very early by a neighboring VBS) and a small bath house. They may have a volleyball net, I can’t really remember. There is a boat launch as well. From Camden, Go East on Eva Road. It does not have a swimming pool(unfortunately, here on Unilocal,there is not a toggle choice of ‘swimming’ alone).
