The mountain is located between the province of Imperia, in Liguria, and the province of Cuneo, in Piedmont. In the SOIUSA (International Standardized Mountain Subdivision of the Alps) it gives the name to the Dorsale della Rocca delle Penne, a ridge starting from the main chain of the Alps at monte della Guardia which, heading south-east, divides the valleys Arroscia and Pennaviare/Neva.
