How much is the entrance fee for the day if you just want to go swimming?

There is no admission to swim. The best place to swim is at the end of the road to the boat launch, on your left just before the launch area.

Earlier review is incorrect there is swimming there. It isn't directly off the campground but down aways from it. I don't know the amount but the parking lot is very small and fills up quickly.

There is no swimming area at keowee toxaway state park. There may be swimming areas on lake keowee but keowee toxaway state park is not one of them.

If I remember correctly, it was something like $7 per car.
