A special discovery for us, to see a Beaver swimming in a lake and so close to civilization. Made the whole walk a success

Behind the road is the large Camping Municipal. There is a hotel with a bistro on the beach in front of the street. The other stands for crepes, fries, etc. were still closed in June. Even further west is a large picnic area in the forest. The beach is also monitored during the summer holiday season. You can rent treet boats. The water is not too cold. A beautiful, quiet, large lake for swimming.

Nestled in the middle of the woods, you will find this fishing pond which offers you a nice run along its banks. The paths around the pond are well laid out due to fishing access.

The Porte de Cosne was formerly known as the Porte du Vieux Château de Cosne. In the 9th century the village was surrounded by a wooded fortification until in the 12th century stone fortifications began to be built. Looking closely, one can see that the roof of the gate is exceptionally steep. The tower that originally existed was to be over 20 meters high and closed with heavy gates and a portcullis to prevent enemy attacks.

A pond reserved for fishing (there are apparently beautiful carp). The road that runs along the shore through the woods is very pleasant.
