Remote Castellorizo’s Blue Caves provide a spectacular natural geological phenomenon. Known as Parastas Cave or Fokiali (due to “fokia” – seals found here). Boat trips take travelers to the area when the sea is calm, allowing boats to just pass through the cave mouth. Inside, the 75m long, 40m wide and 40m high walls take on an irridescent blue-green color, giving the grotto a fairy-like atmosphere.
