Reprua River, Subterranean river in Gagra District, Georgia
The Reprua is an underground river that flows through limestone formations and emerges near the Black Sea coast in the Gagra District. The water travels through an extensive network of subterranean channels before reaching the sea on its short journey.
The river system developed over thousands of years through erosion of limestone bedrock, creating an extensive network of underground waterways and caves. This geological process shaped the distinctive conditions that define this underground landscape.
Local people tell stories of three sisters whose tears created the Reprua, Anikhamtsa, and Bagarepsta rivers after learning of their brother's death. This legend remains alive in the region and shapes how people understand these waterways.
Visitors need local guidance and proper permits to reach this site, with water flow strongest during spring months. The best time to visit is when water levels are higher and local guides are available.
Between where it emerges from the ground and the sea, the river measures only about 18 meters on the surface. This makes it one of the shortest rivers in the world and creates a unique journey from underground channels to the ocean.
