According to SOIUSA (International Standardized Mountain Subdivision of the Alps) the mountain range is an Alpine supergroup classified in the following way:[1] Borders of the Alpi Biellesi are: The Alpi Biellesi are divided into two alpine groups, one of them further subdivided in subgroups (in brackets is reported their SOIUSA code): These two subgroups are connected by Bocchetta del Croso.

Thus hills and mountains (i.e. Monte Barone) located south-east of the line can be considered part of southern Apulian foreland while most part of the range, located NW of the line, geologically belongs to the crystalline zone of the Alps.

[2] In the Alpi Biellesi are located some ski resorts: Oropa (Biella) in the western part, with downhill skiing slopes ranging from 1,335 to 2,391 m;[3] Alpe di Mera (Scopello) and Bielmonte in the eastern part of the range.

Near Bielmonte is also possible to practice cross country skiing with more than 30 km of maintained trails starting from Bocchetto Sessera (1,373 m).

[7] The Alta Via delle Alpi Biellesi (literally high way of the Alpi Biellesi), a long-distance hiking trail which requires some climbing skills, covers the mountain range starting from Piedicavallo and ending in the village of Bagneri (Muzzano).
