One of the most beautiful beaches on the island of Korčula is the Pupnatska luka, 

Deservedly popular, Pupnatska Luka is a beautiful & deep pebble beach located a few kilometres from the village of Pupnat. The best way to reach Pupnatska Luka beach is by car/scooter (you must pay for parking) or we can arrange a private return transfer there. There is a restaurant selling grilled meats, seafood, fish and salads and a bar selling cold drinks and more snack style food. You can also hire kayaks, sun loungers and umbrellas at Pupnatska Luka (which you may need as there isn’t much natural shade there).
