Nice beach between Sfakia and Frangokastello. Extensive, with few trees for shade, and large, round pebbles. The beach is not organized but you can find there a restaurant. Just in case make sure you have the essentials. Road access from the village Nomikiana.
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.
Walking the beach Vertigo towards Loutro and the footpath E4 will pass the Chapel of the Holy Cross and of course will start next to several small bays which dominate the pebble, sand and rock. There is no organization, and should arrange for all necessary.
