Korcula is a wonderful historic town (on the island of Korcula :-) ) And there's a wonderful swimmable beach ... rocks just outside the east city wall, under the restaurant walking path. You'll be under pine trees, on rocks, with some steps leading to clear water.. can't get much better than this!
There are easy walking steps from the wall down to the rocks, in several places. Much recommended!

Korcula obviously also has a ton of really good restaurants and other tourist services. There's even a red submarine if you are so inclined. But it isn't yellow.
