The mountain lies in the territory of Mazzarino, in the province of Caltanissetta, and is a sandstone relief whose conical-pyramidal profile results from wind erosion.

The mountain lies in the territory of Mazzarino, in the province of Caltanissetta. Its name, Monte Formaggio ("cheese mountain"), is a local toponym; the slopes are covered by ampelodesma grasslands, low palm and cistus scrub, and eucalyptus reforestations, vegetation a visitor can recognise on the climb.

Monte Formaggio lies in the comune of Mazzarino, in the province of Caltanissetta, and no marked trails or maintained paths are documented on its slopes. The cone-shaped sandstone relief is shaped by wind erosion, so surfaces are exposed and shade is scarce. Approach from Mazzarino and carry your own water; the vegetation is low ampelodesma grassland, dwarf palm and cistus scrub.

Monte Formaggio is the type locality of two rare orchids endemic to Sicily: Ophrys mirabilis and Ophrys subfusca flammeola. Botanists cite the mountain in the scientific literature because the specimens used to describe these taxa were collected on its slopes.
