The mountain belongs to the Ligurian Alps and is located on the main chain of the Alps. On its top three ridges meet: on the northern one a saddle at 2.207 m, sometimes named Colle di Capoves, divides the Cima di Pertegà from the Cime de Capoves (2.260 m). Going east a mountain ridge starts from Cima di Pertegà dividing Carnino valley (a north) from the central part of the Tanarello valley, while going South the Cima di Pertegà is divided by the nearby Cime de l'Eveque and Monte Bertrand by the steep saddle of the colle delle Selle Vecchie. On the Italian side of the mountain runs a former-military dirt road connecting Monesi (a village of the municipality of Triora) with the colle di Tenda. The summit of the Cima di Pertegà is marked by a boundary marker, and close to it is located a small summit cross.
