Šavnik is a small town in northern Montenegro and it is located on the southern slopes of Durmitor in a canyon of River Pridvornica, which makes River Piva with all other tributaries. It originates from 1861 as the settlement, when immigrants from other parts of Montenegro and Herzegovina settled it. It is located at 867 m above sea level and close to Žabljak and Durmitor Mountains makes this town interesting in winter. Lovers of nature here can see a unique phenomenon on the River Šavnik, which, in the summer for a couple of hours, is almost completely dried up, and then rise again. This natural phenomenon is actually due to karst springs that are connected by an underground aquifer that are during aridity unevenly filled and emptied.
