Porto Katsiki is definitely one of the best beaches in Lefkada and probably the west coast of Greece. I suggest that you go to the beach pretty early, as the parking gets filled up and it will be difficult to find free parking. I personally like to go to organize beaches, which there are plenty of. You can also find a secluded area of the beach that is open to the public, and you’re able to bring your own towels, umbrellas, and food. Enjoy!
