## Geography

The Solo River (known in Indonesian as Bengawan Solo) "divides" this regency into two parts. The northwestern part is commonly lowland and wavy, forming the catchment area of Surakarta city, while the southeastern part is mountainous.
Near the northern border are the suburban areas surrounding Surakarta City such as Grogol, Baki, Gatak, and Kartasura, while the whole regency lies within the metropolitan area of that city. Kartasura is the junction of the Solo-Yogyakarta track with Solo-Semarang.
Sukoharjo Regency is crossed by the Solo-Wonogiri railway, which re-opened in 2004 after being unused for many years. This railway is one of the most "dangerous" ones in Indonesia because it is located beside the main road without any barrier.
