Fodor's Expert Review Pont Viaduc

The best views are to be found from atop the Pont Viaduc (or la Passerelle). Built in the mid-19th century, this 290-meter-long bridge spans the valley and offers magnificent glimpses of the rocky ledges—partly natural, partly man-made—on which the city was founded. Below you can see the (normally) beautiful Vallée de la Pétrusse, a broad park full of willows that lies in the canyon of the Pétrusse River.
