Kythnos

One of the lesser-known islands of the larger Cyclades. Few foreigners visit, and the island – known also as Thermia, after its renowned hot springs – is even quieter than Kea, particularly to the south where drives or long hikes from Driopida to its coastal coves are the primary diversion. This is truly a place to lounge on sunbed beaches without having to squeeze for space. The most famous and impressive beach is arguably Kolona, which is a long strip of sand, forming two sandy beaches on both sides.
