North of the Alphubel is the higher Täschhorn, the southernmost top of the Mischabel, from which it is separated by the saddle of Mischabeljoch (3,847 m), while the ridge to the south is less prominent running via the Alphubeljoch (3,771 m) to the Feechopf (3,888 m) and Allalinhorn. While the terrain drops steeply into the Mattertal valley to the west, the east side is flat and, compared to its neighbours, almost smooth. The characteristically flat summit of the Alphubel is mostly covered with firn and has, in addition to the main summit, a northern top of 4,188 m, which barely rises above the flat summit area.
