It is bordered on the north by Salas, on the east by Grado, to the south by Somiedo and Teverga, and on the west by Tineo.

Here the fauna is varied and abundant, including wolves, foxes, badgers, roe deer, boars, and brown bear.

The inhabitants of the municipality are in 66 principal villages divided into 15 parishes, the largest of which is Belmonte, with 32.1 km2.

Like many of the municipalities in the mountains of Asturias, Belmonte de Miranda is losing population.

It is done on small ranches and many of the ranchers are of advanced age, which endangers the future of the enterprise.
