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”!

The Garabit Viaduct, built by Gustave Eiffel three years before the Eiffel Tower in Paris, is THE historical monument of Cantal! It is a railway viaduct 565 meters long and 122 meters high which made it possible to cross the Truyère on the line linking Neussargues to Béziers.

Although the current footbridge is of definite tourist interest, it is not the first footbridge over the Truyère in Chaliers. We can thus guess the pillars of this old footbridge on each side of the banks.

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