Testament of the calcareous nature of Monte Malbe, Trosce (dialectal name for ‘puddles’) are small ponds or pits flooded with rainwater, often dry in the summer, which naturally form in wooded environments following abundant rainfall. They constitute an ecosystem of considerable naturalistic value, both for their particular location and for the presence within them of a remarkable biological richness. They are also an important source of watering for local wildlife.
One of the largest and most important in this area is the ‘Troscia del Melo‘ (also called ‘Troscia Grande’) which owes its name to the presence in the past of a large apple tree.

The wooded area of ​​Mount Malbe lends itself well to the seasonal formation of these phenomena, and there are two marked trails that allow you to meet these fascinating ‘pools’ of water along the way: the Track #4 Campore and Track #2 Le Trosce.
