The Sázava (Czech pronunciation: [ˈsaːzava]) is a river in the Czech Republic, a right tributary of the Vltava River. It flows through the Vysočina and Central Bohemian regions. It is 225.9 km (140.4 mi) long, making it the 6th longest river in the Czech Republic.
Etymology
The first written mention of the river is from 1045, when it was called Zazoa in a Latin text. Other early spellings of the name were Zazaua and Sassava. There are several theories about the origin of the name. One of the more likely theories says that the name could be derived from the Proto-Slavic verb sadjati (modern Czech sázet, usazovat), meaning "to sediment", "to sink to the bottom". According to another theory, the name has its basis in the Celtic word sathá, which meant "grove, forest", as well as "swarming, flickering".[1][2]
Characteristic
The Sázava originates in Cikháj in the Upper Svratka Highlands at an elevation of 757 m (2,484 ft) and flows to Davle, where it enters the Vltava River at an elevation of 200 m (660 ft). It is 225.9 km (140.4 mi) long, making it the 6th longest river in the Czech Republic. Its drainage basin has an area of 4,349.8 km2 (1,679.5 sq mi).[3]

Tourism
The Sázava is considered one of the most beautiful rivers in the country and is among the most popular rivers for river tourism. The area around the river is associated with the Czech tramping movement. About 208 km (129 mi) of the river from Žďár nad Sázavou to the mouth is navigable.[5] The most popular section is Týnec nad Sázavou–Pikovice.[6] Between Světlá nad Sázavou and Ledeč nad Sázavou is the Stvořidla Nature Reserve with the most difficult rapids in the Czech Republic.[7]
