The Weiselberg is located in the southeastern part of the Saar-Hunsrück Nature Park immediately west of the village of Oberkirchen through which flows the Blies tributary of the Oster which rises on the north-northwest of the hill. Oberkirchen itself is in the municipality of Freisen. To the west-northwest rises the Leichweilerbach, a left-hand headstream of the Betzelbach. To the south is the Weiseler Born, the source of the Oster tributary, the Wilmesbach. The northern hill spur of the Weiselberg is the roughly -high Mittelberg, whose terrain transitions into the hill of Hochrech.
