Oh this beauty! I live about 2 hours away from Lefkada and it is one of my favorite islands because these colors are unique! Porto Katsiki beach is outstanding, this light blue color of the sea, those huge breathtaking cliffs. 😊 I hate the fact that the beach is fully organised and so much crowded with loud music, but I guess this jewellery couldn't be hiden. There is also a similar beach called "Mylos" at "Agios Nikitas" village which is worth visiting.
Yes, Lefkada has the best beaches I've seen in Greece. Thanks for the feedback! 👍
