They are considered to be part of the Central Eastern Alps. The Oberhalbstein Alps are separated from the Lepontine Alps in the west by the Splügen Pass; from the Plessur Alps in the north by the river Albula; from the Albula Alps in the east by the Septimer Pass and the river Gelgia; from the Bernina Range in the south by the Val Bregaglia.
