Drina

The Drina is a 346 km (215 mi) long Balkans river that forms much of the border between Bosnia and Herzegovina and Serbia. It is the longest tributary of the Sava River, as well as the longest karst river in the Dinaric Alps, and is part of the Danube River watershed. It gets its name from the Roman name for the river (Latin: Drinus), which is derived from Greek (Ancient Greek: Dreinos).

The Drina flows from the confluence of the rivers Tara and Piva in the glen between the Maglić, Hum, and Pivska Planina mountains, near the villages of Šćepan Polje (Montenegro) and Hum (Bosnia and Herzegovina).

The Drina is part of a rafting route that also includes the Tara. There are a variety of rafting routes available, ranging from 18 kilometers (11 miles) to one-day runs from Brstnovica to Šćepan Polje.

Since 1994, the Drina Regatta has been an annual tourist and recreational event organized by S.T.C. "Bajina Bašta" and the municipality of Bajina Bašta. The regatta is the most popular event in Western Serbia, as well as the region's main summer event on the water.

The Šargan Eight is a narrow-gauge heritage railway in Serbia that runs from Mokra Gora to Šargan Vitasi station, with an extension to Višegrad in Bosnia and Herzegovina that was completed on August 28, 2010. Passengers will be transferred to a boating tour along Perućac Lake as part of the route.
