14. Marocche Nature Reserve, the "Moon Valley" along river Sarca
An easy excursion in a truly unique environment in another dimension of time and space
This nature reserve, meaning an area which is protected because of its unique natural and geological features, is the largest post-glacial landslide in the entire Alps: an imposing mass of rocky debris which gives the area a lunar appearance and a habitat for plants and animals which have adapted to this particularly arid environment.
During your visit be sure to examine the dinosaur tracks on a great boulder along the trail: they date back to over 100 million years ago! And if you are into botany, watch out for the natural bonsais you will find among the rocks: they are true “dwarf trees” which due to the harsh environmental conditions have short branches and underdeveloped trunks. These trees do not usually manage to grow more than a metre high, even though they are often over a hundred years old.
The Marocche di Dro are a Site of Community Importance, belonging to the Natura 2000 Network.
