Do not try it.
You need a 4 wheel drive jeep to get close.
By "close" I mean that you would only have to jump from sharp rock to rock for another 20 minutes inside a river path. Bees will keep you company during your trip.
The beach is very dirty from sea weeds and trash from the sea.
It's not a hidden treasure, we didn't even bother to swim after all this trouble and we just returned.
Wild, deserted beach, waves are to be expected at Meltemi. Cool water even in summer due to spring water.
