This is one of the (or maybe even thé) best site for observing hundreds of Common Crane in Western Europe. They tend to fly towards or from the lake in early morning and evening between November and February. Suprisingly, it's quite a scarcely visited area with only the occasional cyclist, jogger and, of course, a birder coming by.
From the village, just walk up to the Digue and find a good place to overlook the lake. Personally, I would recommend one of the vantage points as seen on the map.

Note: this is primarily a winter site, and that spring and summer are little interesting when it comes to birds. The Common Crane will be present from early November to March.
The entire Lac du Der region offers fantastic birdwatching in winter and autumn. I recommend visiting both the "Observatoire du Oiseaux" on the other side of the lake, and also the "ferme aux grues" (easily reached via GPS). The former holds a huge hide with two floors and a visitors center and the latter is a farm where the farmer drops maize on his fields, which attracts the Common Crane. The latter site also has a big observation tower.
