Gajniče is a clustered village on the southern slope of Roj Hill (330 m), which also has a railroad tunnel. A wet, marshy valley lies below the village, through which Tlake Creek (Slovene: Tlaški potok) flows, with its source at Vir Spring below the hamlet of Razdrto. The creek flows through the low-lying Snožeti Meadows.[5] Klobušter Hill (396 m) and Mačka Hill (397 m) rise above the settlement to the south.[6][7]
