21. Nantes, France
It’s a middle-sized French town just below Brittany, with stunning architecture. It’s full of trees and flowers and also is very interesting culturally: I reckon Le Lieu Unique may be the only place in the world which is a cafe, a bar, an art gallery, a restaurant, a gig venue, a sauna, and a bookshop at the same time. Trentemoult across the river is absolutely lovely, and it’s less than an hour’s drive from the beach. There’s also lots of great food and wine.
