The Ober Gabelhorn has a pyramidal shape, similar to the nearby Matterhorn but on a smaller scale. Only the smooth north face is completely glaciated, the other faces being mostly rocky. The south-west ridge is called the Arbengrat while the north-north-west ridge is the Arête du Coeur. The south-east ridge looking over the Ober Gabeljoch (3,597 m) is the Gabelhorngrat. The Wellenkuppe is a lower prominence on the north-east ridge; it is usually climbed as part of the normal route.
