The Sava is situated in central Europe and, although it is not as well-known as some of the other major rivers, it is the largest tributary to the mighty Danube. During its course, the Sava flows through Slovenia, Croatia and Serbia as well as acting as the border between the latter and Bosnia and Herzegovina.

It rises in the nature reserve of Zelenci Springs, close to the Italian and Austrian borders, before travelling 615 miles to meet with the aforementioned Danube in Belgrade. This is just one of three capital cities that the Sava flows through; the others being Ljubljana and Zagreb. As well as being used for fish farming, water from the river powers hydroelectric power stations and cools thermoelectric and nuclear plants throughout Slovenia. Its water serves people in six different countries and even reaches those living in the northern parts of Albania.

The Sava is navigable by river ships between Sisak and Belgrade. As well as these two ports, you'll also visit places such as Slavonski Brod, Brcko and Sremska Mitrovica. Along the way, you'll get to discover peaceful Boroque towns, visit citadels and monasteries, admire Ottoman influences and even learn about Serbian art. Your Sava River cruise may also include time sailing the nearby Tisza River, another important Danube tributary.
