The Tuhinj Valley (pronounced [tuˈxiːn]; Slovene: Tuhinjska dolina) is a valley in Slovenia linking the Celje Basin with the Ljubljana Basin in an east-west direction along the courses of the Nevljica and Motnišnica rivers.
Their drainage divide is at the Kozjak Pass at an elevation of 655 m between Cirkuše v Tuhinju and Špitalič.
The large number of old settlements points to the fact that the valley was an important thoroughfare in the Middle Ages and later as a passage between Lower Styria and Upper Carniola.
This root is also the source of similar names such as Tuhinje in Herzegovina, Tuin in Macedonia, Tukhin in Russia, and Tuchyňa in Slovakia.
Tourism has only recently started to develop with the building of the Snovik Spa.
