Superb view of the Garabit viaduct, allowing you to cross the Truyère gorges. This metal structure, created by Gustave Eiffel, is 565 meters long and rises to 122 meters above the water. It was at one time the “highest viaduct in the world”!

Ruynes-en-Margeride is recognizable from afar thanks to its 12th century tower. The latter houses the Margeride eco-museum as well as the garden of Saint-Martin. The beautiful fountain located on Place Gambetta is also to be discovered.

The name of Saint-Flour comes from Florus, a bishop who came to evangelize the region in the 4th century. The city, located on a volcanic promontory, is doubly protected by ramparts and fortified gates. In the 14th century, the city, due to its importance within the Cantal region, received the prestigious title of religious capital of Haute-Auvergne. The numerous buildings from this period are an integral part of the city and contribute to its beauty.

A very original viaduct that reminds us of a world-famous Parisian tower, not surprising since it was designed by Mr. Eiffel too!
