The cave of Vreiko is located about 2km north-east of the Pefki village. It is a cave and gulch and the known depth is 25-30 metres.
The Entrance is an open and flat place that looks like a threshing floor. In the entrance there are stairs that make the entry and exit to the cave easier.
A fig tree has grown at that place and its bouches cover a big gallery which is about 60-70 metres long.
At the entry and the end of the gallery there are signs from the Neolithic Era.South of the entrance is the gulch (Latsida) where there is water which dries up during autumn.
At this part of the cave there metallic stands to assist people on their ways up and down. In every corner of the cave there are beautiful stalactites and stalagmites.
It is not difficult to visit this cave as cars can go about 250 metres before the caves entrance on the west side and almost on a daily basis, during summer months people visit the cave.
