Kythnos is one of the least-visited islands in Greece, despite (or perhaps because of) being so close to Athens.
Those who skip past is are missing out on this beauty of a beach. Kolona is one of several double beaches in Greece, with water on either side of its sands. Many yachts make a stop here on their way out of the marinas in Athens. If you don’t have yacht of your own then you’ll have to make do with a water taxi or an intrepid hike from the port.
Although the world is generally a safe place, and strangers are often more kind and well-meaning than evil, there are locations where travelers typically shouldn’t venture, places ravaged by wars, terrorism, civil unrest, or violent crime.
