There are numerous karst caves on the territory of Imereti. In order to protect them and preserve natural environment, in 2007 Imereti Cave Preserve Territory was set up. It includes one preserve, one managed nature reserve and 18 natural monuments, including: Sataplia reserve (330 ha), Sataplia managed nature reserve (34 ha), Tetra Mgvime, Prometheus, Khomuli, Gliana, Satsurblia, Solkota, Didgele, Melouri and Bgeri natural monuments of caves; Navenakhevi, Nagarevi, Iazon and Sakazhia natural monuments of caves; natural monuments of Tskaltsitela gorge; natural monument of Tsutskhvati cave. Prometheus cave (Tsqaltubo district, village of Kumistavi) was discovered on June 15, 1984, by expedition of speleologists from Tbilisi Vakhushti Bagrationi Institute of Geography. In 17 halls of the cave there are a lot of beautiful cold lapped shapes of stalactites and stalagmites, helictites, pisolites, "waterfalls in stone", "stone curtains". There is a 1050-meter-long track in the cave. However, it is supposed that overall length of the cave exceeds 20 000 m. Climate of the cave is wholesome for people suffering from asthma. "Sataplia" sobriquet is linked to bees which arranged their beehives in the clefts of limestone from times immemorial. The cave is a natural riverbed for river Ogaskuri. During 30 million years this small rivulet step by step tried to make its way and widened corridors of the cave. The cave was accidentally discovered by the curator of Kutaisi museum, Petre Chabukiani, in 1925, while exploring and looking for stations of ancient hominids.
Gigantic dinosaurs stationed in the managed national reserve of Sataplia around the cave millions of years ago. Their tracks have been preserved up to the present. Sataplia was the fi rst karst cave in Georgia where tourist infrastructure was arranged. To the South of village Tsutskhvati in Tkibuli distric, at 250-400 m above sea level, karst cavity "Magara", second in the world by its age and number of levels, is situated. There are 13 levels in the 75 m vertical section of the cavity. The cave was used for cultic purposes. Tsqaltubo cave, nicknamed "Tetra", is a karst cave in the environs of the village of Khomuli. High background of aerial ionization and natural radioactivity, ideal purity of air, existence of pathogenic microbes and allergens, stability of basic meteorological elements (air temperature, humidity, atmospheric pressure) create favorable conditions for treatment of chronic asthma and cardiovascular system diseases. Environment of the cave is also good for treatment of hypertensive, chronic pneumonia and neurosis diseases. General length of the 4-hall karst cave in Terjola municipality, on the territory of the village of Navenakhevi, is 210 m, maximum height - 18 m, there are 120 stalagmites in the cave that exceed stalagmites available in caves of Sataplia and Akhali Atoni.
