Aggitis Cave.

The cave can be visited in a length of 500 meters while in total it extends in a length of more than 21 kilometers. Its peculiarity lies in the fact that on its floor flows the river Aggitis, with an impressive exit of the river through the mountain. The underground river of the cave ends, among others, the waters of the basin of Kato Nevrokopi, while the cave belongs to the network of caves of the gorge of the river Aggitis along with four other known caves, including the famous Alistrati Cave. The cave is also called Maara, a name whose etymology is either from Arabic and means small cave or from Hebrew which means water from the mountain.
Alistrati Cave.
Alistrati Cave is one of the largest caves in Europe. Its rich decoration includes, in addition to huge stalactites and stalagmites in various colors and the rare eccentrics. Eccentrics or elitites are rare formations created by "defying" the laws of gravity and following irregular paths. The main feature of this cave, which makes it unique in Greece, is the very large variety of eccentrics. It is also characterized by the unique microscopic organisms (3 mm) found within it, such as Alistratia Beroni, a unique species of isopod. The visitable corridors are about 3 km long and the cave belongs to the network of caves of the gorge of the river Aggitis along with four other known caves. Alistrati Cave is located 6 km southwest of the town of Alistrati in Serres, at "Petroto" and is accessible from both Drama and Kavala, as well as from Thessaloniki (via Serres or Asprovalta). It has been used and can be visited since 1998. A stone's throw from the technical entrance of the cave, is the gorge of the river Aggitis.
