Zigana -

Above Limni Gölü Nature Park, drive towards Karaca Cave. After about 500 meters, there's a plateau on the left side of the road with enough space for several campers. During the day, locals picnic here; at night, you're alone at an altitude of 2050 meters. Apart from 4G, there's no mobile service; only self-catering with everything on board, including a toilet!
