Podgora is located in the northern part of the Dobrepolje karst polje. It lies in a transitional position between the edge of the polje and the steep slopes of the Little Mountainschain, with inclines up to 29.5°. It is the only village in the polje located almost entirely on Triassicrock. A major Dinaric fault runs past Podgora. The area is rich in springs, with five in Podgora alone. The largest and best-known spring is Žovkno Spring. The other springs are Beč and Zajščica springs in the village itself, nearby Pri Koritu Spring, and Puhovka Spring in Puh Cave just below the top of Grmada Hill.
