Bojanja Vas is a clustered village on a slope on heavily karstified terrain. There are small fields on poor-quality soil to the south, vineyards to the east and south, and woods to the north and west. A water main was connected from the Jamnik Ridge northeast of the village in 1965, with the main water reservoir located west of the village, near Glavica Hill (493 m). Nearby caves include Kip Cave (), Šulnovka Cave, Kadiš Cave (), Role Cave, and Tončik Cave (). The Pečenjevka Chasm is located northeast of the village, where there is a 50 m waterfall from Jamnik Creek during heavy rains.Savnik, Roman, ed. 1971. Krajevni leksikon Slovenije, vol. 2.
