What an interesting park! it has been recently updated with fun games for children, and on the weekend there is a book market as well - mostly for books in French and occasionally foreign language titles. due to the large number of family visitors, you can look for help when you need (there was a kid who hurt herself and not one but three kind paramedics came to soothe and assist). otherwise, because it is a park commemorating a famous figure in French culture, a singer-songwriter-poet and more, there are poems sprinkled all over which you can enjoy. or bring your own books to savour. Highly recommend.
The scenery is very good, and the greenery around the lake is also pretty good.
