Ohhhaaoy!!!Lefkada is an exotic island!!!it has the very very best beaches i have ever seen in my life,And there are so many:porto katsiki,egremnoi(the best tin greece and surely in europe),kathisma etc etc.The colour of the water ,the sun, the sandy beach feel like you are in paradise
There is not a greek island or any other medditerannean spot where you can find such a beatiful beaches.
Speaking for the island well ok it is not corfu,rhodes or saint trope but it has a nice town and a lot of beatiful villages.The food is really really good(and surely better than other famous greek islands).But as i said you already the main reason where you MUST have a trip to this island is beacause of its beaches.At the moment this island is not as famous as other islands(which are near the town of greece) and i think is a good point .
