The Ober Gabelhorn lies in the Swiss canton of Valais at the southern end of the Zinal valley (part of the Val d'Anniviers). It rises, together with the Dent Blanche (west) and the Zinalrothorn (north), above the Zinal Glacier. On the south side lies the Zmutt Glacier in the valley of Zmutt, which extends west of Zermatt.
