I wanted to post a straıghtforward answer to your questıon about accessıng Gemikonağı, but the thread has been locked. I cannot confirm whether this is the Turkish name for Xeros, but I do know Gemikonağı; I have travelled through it on the way to Lefka. It looks like quite an ordinary settlement to me with people sitting outside coffee shops and walking along the street. I can't imagine that access is forbidden. You can get there on the bus from Nicosia to Lefka/Lefke which runs every half an hour until 5 pm (no service saturday afternoons or Sundays). Usually you have to change to a smaller vehicle at Güzelyurt/Morphou, but there is one ticket for the whole journey. Buses depart from the bus terminal in north Nicosia. If you cross at Ledra Palace this isabout two miles away. Go to the Girne Kapısı/Kyrenian Gate then turn left and follow the main road: you can't miss it when you get there.
Hope this helps.
