The Karlsruher Grat is situated in the nature reserve Gottschlägtal-Karlsruher Grat to the East of Ottenhöfen and southward of the Hornisgrinde in the Northern Black Forest. The nature reserve reaches from the western falls of the Melkerei and Vogelkopf at 400 meters up to 830 meters above sea level to the East. There the street Kreisstraße 5370, leading from Oppenau to Kloster Allerheiligen to the Schwarzwaldhochstraße, marks the border to the national park Black Forest and to the nature reserve Schliffkopf. The ridge runs at about 750 meters above the Gottschlägtal.
