The Otskhe River

The Otskhe River: The River of Abastumani

The Otskhe River (მდინარე ოცხე) is a river in the Adigeni Municipality of the Samtskhe-Javakheti region, famous for flowing through the historic mountain spa resort of Abastumani. As a left tributary of the Potskhovi River, it originates on the western slopes of the Meskheti Range and carves a deep, narrow, and exceptionally beautiful gorge. This gorge is renowned for its dense coniferous forests, incredibly clean air, and unique microclimate, which have made Abastumani a celebrated destination for treating respiratory illnesses for over a century.

The river is the central feature of the resort town. The main road through Abastumani follows the river’s course, and the town’s historic buildings, including old sanatoriums and a palace of the Romanov family, are built along its banks. The river valley is also home to the world-famous Abastumani Astrophysical Observatory, which was placed here due to the exceptional atmospheric clarity of the location. The Otskhe is therefore not just a river, but the heart of a unique landscape of healing, science, and history.
