It rises in the central massif, at the Mont Gerbier de Jonc, flows from there to the north by Roanne and Nevers, with Orléans changes it their direction and flowsthrough route toward the west. With Saint Nazaire it flows into the Atlantic ocean.
In the underflow the Loire is still another free-flowing river, since no dams or air-locks disturb their natural run. In the upper run the Loire was several times accumulated starting from Roanne. In the years 1856, 1866 and 1910 arranged the flood of the Loire large damage.
