Loška dolina valley (The Lož Valley) is a hidden corner of the unblemished karst fields in the south of Inner Carniola, very near the Croatian border. It is located about 70 km south of Ljubljana.
It is surrounded by mighty forrests covering the diverse karst highlands. When coming to Loška dolina valley from the north and over the Bloška polica plateau into the medieval Lož, the road leads straight into Stari trg pri Ložu, the administrative center of the municipality. Following the road further down south lies Babno polje, very near the Croatian border. Racna gora and its ridges, the mountain barrier in the east, separates the Lož valley from Loški potok. Snežnik (1796m) is the Inner Carniola mountain peak in the south, whereas the oblong forrests of Javorniki in the west, set a barrier between Loško polje (field) and Cerkniško polje (field).
The valley stretches from 570 to 590 meters of altitude. It differs from the rest of karst fields in the Ljubljanica basin, as far as the water regime is concerned, aswell as in its positioning and the economic use.
Loška dolina extends over 167 km2 with a little less than 4000 inhabitants that live in 21 villages. With its 23 inhabitants per square km, it is listed among municipalities with the lowest density of population.
