The Gonatos Caves are situated at the east end of Plakias Bay. They used to be brown coal mines before the Germans dug them out in WWII, using them to refuel and supply their submarines.
It is very nice walk from Plakias to the caves, with great views over Plakias Bay. The tunnel between the two caves is pitch black so don't forget a flashlight and watch your head (Gonatos is Greek for knee)!
For precise directions use walk 15
Tip: The views from the caves and the walk up to them are especially stunning at sunset!
