It is located in the southeastern part of the Great Plain, on the Körös plain, on the left bank of Fehér-Körös, right next to the Romanian border. It is located in one of the deepest areas of Hungary, at an altitude of 88 meters above sea level, in a flat area. The climate of the region is moderate and continental.

The nearest neighboring town is Békéscsaba, which is 16 kilometers west of it.

Fehér- and Fekete-Körös are among the cleanest rivers in Hungary; the riverbanks and forests located here - which have now been classified as protected areas - are particularly beautiful in terms of landscape. The city itself has a significant tourist role with its many parks, monuments, and cozy streets, and last but not least, its character as a spa town.
