The valley of flowers and the dead city

In the Urtier Valley there are rare botanical species and vegetation typical to the Alpine area, but what makes this excursion truly original is the visit to Colonna, an abandoned mining village situated at 2,390 metres above sea level which is a unique example of industrial archaeology. From Colonna can be enjoyed a breathtaking view of the Gran Paradiso mountain range and Mont Blanc.
