Kastro is one of the beaches located a stone's throw from the town of Lefkada. It features golden sand and cool waters and it is the beach you come across once you pass the bridge of Lefkada and turn right while left leads to the town.

It is ideal for a refreshing break during the day. Large in size, it is not organized and is known mainly to locals. At the beach there is also the big abandoned TAOL building (Wine Production Cooperative of Lefkada).
