Hron is a popular destination of water tourism.


The name is probably of Germanic origin; *Granahua: gran – spruce, ahua – water.[1]


The name of the river was mentioned for the first time in 170, when Roman Emperor Marcus Aurelius wrote his Meditations at the Hron (Latin: Granus) river.[2] The first recorded medieval name was Gron (1075).[2] From the 17th century until the 1930s, the river was used for wood transport.
