Akhali Atoni Cave, also known as Anakopia Cave or Iverian Cave, is located in Gudauti municipality (Abkhazia), near the city of Akhali Atoni, on the northern slope of Iverian Mountain.
Akhali Atoni Cave is a karst cave and has an abyss-like entrance that is 60 meters high. The notable cavities are "Aphkazeti,", "Iveria," "Moskovi," "Sokhumi," "Tbilisi," "Helikitebis," the petrified waterfall "Afsni,” and others. Some chambers have beautiful stalactites of various shapes and sizes draped over the walls in cascades.
The bottom of the cave system is 50000 square meters, and the volume is over 1.5 million cubic meters. It is one of the biggest caves in Europe in volume and is among the top five karst caves in Georgia. Water submerges the cave's south chambers during floods. The lowest chamber of the cave is filled with water. There are arachnids, crustaceans, and other specimens here.
The Vakhushti Geography Institute at the Georgian Academy of Science discovered and explored the cave in 1961. The Institute of Urban Development introduced a project to attract tourists to the area in 1975.
