Kythnos beaches: 70+ bays and a famous sandbar
Kythnos has more than seventy beaches, headlined by Kolona, a slim golden sandbar joining the island to the islet of Agios Loukas, with sea on both sides. Apokrousi and Episkopi are the long, tamarisk-backed family favourites, while Kanala offers pine-shaded coves. End a beach day at Loutra, where natural thermal water flows into the sea.
