Remote beach with sand. Access from the village of Saint Nectarios, or alternatively your own boat. Of course there is nothing on the beach so be sure to necessary.
50 km south of Chania is the mountain village of Askyfou, Sfakia. There is an interesting war museum there, created by a local man, who was travelling all over Crete to collect every vestige of the battle, so as to keep alive the glorious memory of Cretan war history.
