The Biarzo shelter
Location: From Biarzo travel the road to the former mill and continue along the path.
One hundred meters north of Biarzo, including the bed of the Natisone and the escarpment above the river terrace, develops in a few tens of meters a deciduous bush hygrophilous high nature value. At the foot of the rocky escarpment it opens a small cave near a fragment of mesic deciduous forest.
