The Hochstein rises in the High Eifel between the villages of Bell to the north-northeast and Ettringen to the south. Its summit and most of the hill lie in the western part of the borough of Mendig, the village of Obermendig extending as far as the eastern foot of the hill. The west and south flanks are located in the municipality of Ettringen. Northwest of the hill, along its municipal boundary with Ettringen, are the Roderhöfe which belong to Mendig. Somewhat to the north of the hill rises the Kellbach stream and, to the south, the Segbach, which both feed the Nette tributary of the Krufter Bach.
