Gosthani River is one of the prominent rivers in
Visakhapatnam District. It has its origin deep in
Borra Caves and flows towards
Bheemunipatnam, where it meets with the
Bay of Bengal. Gosthani River is a historically important river, which once served as an important navigation canal for inland trade.
The million-year-old Borra Caves, filled with charming stalagmite and stalactite formations, is formed as a result of the action of the Gosthani River. Once Borra was a limestone area and the pressure exerted by the river water on the mineral deposits gradually led to the formation of these caves.
