Mureș

The Mureş is a river in Eastern Europe that runs for 490 miles. It is the third-longest river in Hungary. The river rises in the sources of the river Olt in the Hăşmașu Mare Range of Romania's Eastern Carpathian Mountains and enters the Tisza at Szeged in southeastern Hungary. Its length in Romania is 473 miles.

The Mureș River runs through the Romanian counties of Harghita, Mureș, Alba, Hunedoara, Arad, and Timiș, as well as the Hungarian county of Csongrád. Târgu Mureș, Alba Iulia, Deva, and Arad in Romania, and Makó in Hungary, are the largest cities on the Mureș.

The Hungarian sections of the Mureş are 45 miles long and run parallel to the state border. The Körös-Maros National Park encompasses 11.0 square miles on the river's northern bank. The Maros Floodplain Protected Area comprises gallery woods, floodplain meadows, and a forest reserve in Szeged. In medieval times, salt was traded on the river in enormous rafts.
