The two valleys separated by the range are the Mattertal on the west and the Saastal on the east. The towns of Randa and Saas-Fee lie both six kilometres from the summit (to the west and the east, respectively). The elevation difference between the summit and the valley floor is 3,150 metres on the west side (Randa) and 3,000 metres on the east side (Saas-Grund). On the Mattertal side, the Dom faces the almost equally high Weisshorn and, on the Saastal side, it faces the Weissmies. The Dom is the highest point of the Saastal and the second highest mountain of the Mattertal after Monte Rosa.
