A conspicuous feature of the chain, as of the adjacent tableland, is the number of its parameras, isolated plateaus shut in by lofty mountains or even by precipitous walls of rock.

The north facing slopes receive heavy cyclonic rainfall from the Cantabrian Sea, whereas the southern slopes are in rain shadow. Main ranges The Cantabrian Range has three very distinct sections from west to east: Western The Asturian Massif and its foothills. Geologically it is an eastern prolongation of the Galician Massif with Paleozoic folds. It is cut by deep east-west oriented canyons such as the Cares River valley.
