The biggest horizontal cave in Greece which extends in 1.400 m. The cave has an underground river and is situated at a height 1.220 m. The point of entry of the river in the cave, is also the exit from the cave, and on that spot there is a natural cool waterfall. You can explore the cave during the autumn months, when the water level is low, whereas the rest of the year it might be dangerous. The view is unbelievable and enchanting, not just inside the cave but also in the surrounding wilderness.
