Turtle Lake is located in the South-Western direction from downtown, on the Northern slope of Mtastminda mountain range. It was formed by underground torrents accumulated as a result of staggering landslides of rocks. The length of the Lake is 180 m, width – 50 m, surface area – 0,034 sq.m, catchment area – 0,4 sq.m, mean depth – 70 sm. In summertime Turtle Lake is a beloved place of social interaction and leisure time for the residents of Tbilisi. Swimming season at Turtle Lake starts with arrival of summer. Along with comfortable beach and outdoor cafes and bars, there is a sports fitness center and a cultural and leisure complex on the territory of Turtle Lake, including, but not limited to, mini-soccer stadium of European standards, playground for children, landing and a pontoon-scene for professional performances where various events take place during a season. There was a cable way from the center of the city to the Turtle Lake which was constructed in the second half of the XX century and was operable till 2009. The main purpose of the cable way was to link the center of the city with the Turtle Lake. The distance between station points is approximately 1140 m. The upper station of the cable way is located on the bank of Turtle Lake, at elevation of 700 m above sea level, the lower one is in Vake park, at elevation of 444 m above sea level.

The history of the foundation of Tbilisi is tied with these springs. According to one of the legends, many centuries ago when the capital of Kartli was Mtskheta and the cavity of Tbilisi was noted for its pristine nature and hunting areas, king Vakhtang Gorgasali accidentally ran against hot spring in which his falcon along with hunted pheasant died from burns. The king liked these miraculous springs so much that he ordered to erect a city there that was later called ‘Tpilisi’ (since 1936 – Tbilisi), or ‘warm location’. Vey soon the springs were used for supply of hot water for sulphuric hot baths that are in use up to the present while the neighborhood of these baths is called Abanotubani (‘District of baths’ in Georgian). Tbilisi baths were well known in the whole region of the Middle East. The miraculous properties of sulphuric water were described by the X century Arab geographer, Ibn-Haukal, as follows: “…There are baths there where water is boiling without fire…” Cruel conqueror, Agha Mohammad Khan also believed that his incurable disease could be treated at Tbilisi baths but this was not the case, and disheartened eunuch ordered to level the city. Almost all foreign travelers and famous individuals in the XVII-XVIII centuries, including French visitors Jean Chardin and Dubois de Monteret, botanist Joseph Turnefor, Italian missionary Delaporti, Russian poet Aleksandr Pushkin and others remember and describe in their writings Tbilisi natural hot spring baths. In the second half of the XIX century first substantial research of thermal waters of the Georgian capital was conducted by the German geologist and famous researcher of the Caucasus, Wilhelm Abich. It was this man who preserved for us geological review of this place and pointed out that usage of Tbilisi thermal waters for health treatment is appropriate.
