The Drina River flows through regions characterized by a karst landscape, particularly in its upper reaches in Montenegro and Bosnia and Herzegovina. The karst landscape is formed by the dissolution of soluble rocks, such as limestone, dolomite, and gypsum, which create distinctive landforms such as caves, sinkholes, and underground drainage systems.

In the Drina River basin, the karst landscape contributes to the formation of dramatic scenery, with rugged cliffs, steep gorges, and rocky formations along the riverbanks. The limestone and other soluble rocks in the area are prone to erosion by water, leading to the creation of picturesque canyons and caves.

One notable feature of the karst landscape along the Drina River is the Tara River Canyon, located in Montenegro. Tara Canyon is one of the deepest canyons in Europe, known for its sheer cliffs and stunning natural beauty. It is a UNESCO World Heritage site and a popular destination for outdoor activities such as rafting, hiking, and wildlife viewing.

Overall, the karst landscape of the Drina River region adds to its aesthetic appeal and provides opportunities for recreation and exploration amid breathtaking natural scenery.
