Steno, as the local townspeople refer to it, divides Astypalaia into the eastern part known as the "Inner Island" and the western part known as the "Outer Island". The concrete road towards the "Inner Island" stretches past the successive beaches "Marmaria", "Steno", "Plakis" and the "Blue Limanaki" until it reaches Analypsi or Maltezana after a total of 9 Km. Steno is known for its shallow water and its beutiful sand .
