There are a lot of vineyards nearby Clisson. They produce Anjou Wine (red or white)and the famous MUSCADET.
We enjoyed a 'Porte Ouverte' by a wine grower in Beaulieu sur Layon and we tasted his 'Coteaux du Layon' which is sweet white wine. I brought a sufficient number of bottles to taste for some years in the future.
The seaside is really close to Nantes (40 miles west) and there is the nicest beach in Europe : La Baule.
It's a 15km long beach with a nice sand!!
Once there, you should also see the 'Wild Coast' from Le Pouliguen to Le Croisic...the landscape is wonderful!
There is also a nice house, like a small, very small castle, and another house to celebrate marriaghe (I think). When we left, there was a mrriage taking place up there in the park.
Visit the old city gate. There used to be a wall around this city a long time ago and this gate was the entrance.
The crypt of the Cathedral of Nantes shows the history of the Cathedral and the city of Nantes. Very interesting!
At this picture you can even better view the size of the Cathedral. It's absolutely worth a visit. And you can cool off here, cause it won't be as hot as outside ;o)
