Siret River
The West side of the county are mountains from the Eastern Carpathian group. Here, along the valleys of the Oituz River and Trotuș River there are two important links between Moldavia and Transylvania. To the East side, the heights decrease and the lowest point can be found on the Siret River valley which crosses the county from North to South in the middle. On the East side there is the Moldavian Plateau crossed by many small rivers.
