How is swimming at kerr recreation area ?

Just about every lakefront campsite has it's own personal beach. I would wear foot protection because of the possibility of wayward fishing hooks and occasionally broken glass by people who don't respect our beautiful resources!

You can swim here just people use it to fish

There are some areas where there is beach access to get in the water. At a different part of the park there is an actual swimming area. I don't believe it is stocked with a lifeguard though.
