The mountain belongs to the water divide between Strona Valley (South) and Ossola Valley (North). The southern slopes of Monte Massone are mainly grassy, while its North face is rocky, very steep and covered by shrubs. From Ornavasso, located on its North foothill, the summit can't be seen because is hidden by a subsummit named Eyehorn (2,131 m). On Monte Massone stands a metallic cross 4 ms high bearing a bell, which was located there in 1921. Not far from it, on the Northern slopes of the mountain, can be seen some trenches dug before the 1st World War and belonging to the Linea Cadorna. At 1,900 m, on the Valle Strona side of Monte Massone, there is a small plateau which hosts three tiny lakes called Laghetti, where in the past local farmers tried to implement a project of land reclamation.
