Panorama du Bec d'Allier, Scenic observation point at Marzy, France

Panorama du Bec d'Allier is a scenic viewpoint on an escarpment in the commune of Marzy, at an altitude of about 228 metres, facing the confluence of the Loire and Allier rivers. The Loire receives the Allier downstream of Nevers, and the site offers a view of the meeting of the two rivers.

The site received official designation in 2004 when the World Wildlife Fund recognized it as a Panda River site. This recognition highlighted the ecological importance of the river systems and their confluence zone.

The site lies within the Espaces Naturels Sensibles managed by the Nièvre departmental council, which laid out a trail from the commune of Gimouille and an observatory. The Bec d'Allier was awarded the WWF's "Sites Panda Fluvial" label in 2004 and is part of the Natura 2000 network.

From Nevers, follow the Loire towards Marzy; from Bourges, head via Apremont to Cuffy, passing the Guétin canal bridge, from which the confluence can be seen in the distance. The viewpoint stands on the east bank, on the Nevers side, just downstream of the confluence; a sensitive natural area path and an observatory lie on the west bank, on the Cher side.

The site lies on an escarpment at about 228 m, opposite the meeting of the Loire and Allier. The Loire arrives already swollen by its tributary the Nièvre just upstream of the Nevers bridge, and gains the Allier's waters only after Nevers. WWF classified the Bec d'Allier as a "Site Panda Fluvial" in 2004.
