The Ohm Hills, most of which are densely wooded, whose southeastern foothills form the Bleicherode Hills, lie in the county of Eichsfeld on its boundary with Nordhausen. They are located between Weißenborn-Lüderode to the north, Bleicherode to the southeast, Worbis to the south and Teistungen to the west, and extend from the upper reaches of the River Helme in the north to the Wipper in the south. To the north and west the range is adjoined by historic landscape of the Lower Eichsfeld (Untereichsfeld), further south is the ridge of the Dün and to the southwest the Eichsfeld-Hainich-Werra Valley Nature Park.
