Koutalas Cave in Koutalas
In Koutalas area, a bit higher than the village, there is a natural cave, which you can enter through a downhill dirt road. The interior of its great hall is covered by stalagmites and stalactites, while on the ground there are bones, ancient utensils and some water concentration, like a small pond. Over the cave’s entrance there is a half-ruined gallery of the old mines of Serifos.
It is a very interesting cave, but unfortunately the ground’s stability is doubtful. This is why a metal fence has been placed the last few years, in order to prevent the entrance for security reasons.
