Mt Caplone is the highest mountain of Tremosine. An extraordinary concentration of endemic species makes it of outstanding floristic interest. It is renowned throughout Europe and a must-see destination for botanical trips. There are still many wild environments, barely touched by humans, on the mountains. The site is of national and provincial interest because many endangered animal species live and reproduce here, major glacial relicts exclusive to and/or typical of the Alps.
It is part of a site encompassing the northern flank of the Mt Tremalzo-Mt Caplone limestone chain between the crest and the river Palvico. This very vast, varied area includes the Lorina Valley ravine, the steep rockwall pine woods of the dryer slopes, the little fir woods and ravine woods of the cooler environments, the fertile pastures of the Tremalzo bowl and the grassy-rocky crest and peak zones. There are many habitats of special interest: mixed-fir woods (10%), cave-like rock shelters (1%).
