Lake Kartsakhi, also known as Khozapini, is located in Akhalkalaki Municipality, among the natural attractions of the region, at an elevation of 1,799 metres. It's Georgia's second-largest lake by area after Paravani, at about 26.3-26.6 square kilometres, yet its maximum depth is only around a metre.
The lake, of tectonic origin, is split by a state border: the northeastern part, about 53% of its area, belongs to Georgia, while the southwestern part, including 12 islands, lies within Turkish territory. The water is fed by snow, rain and underground sources, with a salinity of 880 mg/l, creating unique conditions for the local ecosystem. The lake is renowned for fishing, home to crucian carp, common carp, sazan and trout, drawing anglers from across the region. It's also an important birding site, with around 60 recorded species.
The only settlement nearby, the Armenian-populated village of Kartsakhi, sits right on the border, home to both a border crossing and a railway station of the same name. The region is known for extremely cold winters, earning it the local nickname "Georgian Antarctica." Before setting off, it's worth stopping at the Javakheti National Park visitor centre in Akhalkalaki: there you can get maps and directions, and rent a tent, sleeping bag, bike, horse or snowshoes.
