Kiseljak is located in central Bosnia, at the place where the roads that connect all its parts cross.

The average altitude is 475 m. The territory on which the settlement was developed is part of the Kiseljačka basin, which stretches from Paleška Ćuprija in the south to Gromiljak in the north, and is surrounded by Jasikovica, Graščica, Berberuša, Zahor and other hills with an altitude of 700 up to 1423 m.

To the east is the strategically important hill Stogić. The Lepenica river flows through Kiseljak, which receives its tributaries Kreševčica and Rotiljski potok in the settlement, and flows into the Fojnička river on the northeastern outskirts of the settlement.

There are also many medieval finds, and the most numerous are stećci. There are hundreds of them, and only in the area of Lepenica there are 35 necropolises with about 700 stećaks. The most beautiful is the stećak of Radoje Radosalić in Zabrđ.

In the opinion of Dr. Pavle Anđelić, one of the greatest archaeologists in Bosnia and Herzegovina, the stećak from Brdanje is one of the most beautiful in all of Bosnia and Herzegovina.
