This railway is the highest in Europe and gives you access to the marvels of nature and the secrets of the Pyrenean mountains. Sometimes you'll find a shepherd making the trip up to his flocks.

It is one of the most beautiful trips of the region. At 2000 m altitude, you will discover the azure blue Lake of Artouste, and explore the underground galleries that were created to collect the hydro power of the mountains, with the company of a guide.
