This superb bird's-eye view offers an exceptional panorama of **l’Erdre**, captured from one of the bridges that span it (like the Pont de la Jonelière or the Viaduc de la Beaujoire). **A royal river with a lake-like appearance:** The Erdre stretches majestically, wide and peaceful, bordered by dense green wooded banks where large properties and preserved natural areas can be glimpsed. **The call of the great outdoors:** In the distance, the white silhouettes of a few sailboats and light craft dot the blue water, testifying to the nautical activity for which this river is renowned. * **The urban and nature contrast:** In the foreground, the modern, metallic lines of the bridge's railing recall the proximity of the city, creating a perfect graphic transition with the wild softness of the landscape in the background under a sky adorned with beautiful cumulus clouds. A beautiful invitation to contemplation or a stroll along the banks!
