Considering the Ibis Nantes La Beaujoire in Nantes?

Lac de Grand Lieu (20 minutes drive from Nantes) by chess_machine
20 minutes drive south of Nantes, you will find a preserved lake: Lac de Grand Lieu. It is forbidden to fish, swim and boat on the lake since it is a national park that has a very special fauna. Went there last weekend and took some pictures. The lake is beautiful, wild and will surely interest those that love nature.
Best is to check some of the pictures.
