The rivers Latorica and Uzh (Hungarian: Ung, hence the name of the county) flowed through the county.
The pass is located in the Carpathian Mountains just where the oblasts of Lviv and Transcarpathia meet, on the spine of the Northeastern Carpathians, between the Latorica or Latorytsia and Opor river valleys and at the river divide or watershed between the Latorytsia and the Stryi.
