Park Sempione is next to the Sforzesco Castle (Castello Sforzesco).
The park has lovely paths where you can walk, run, or ride. There are ponds with ducks and the place is amazing.
In Autumn the color of the leaves is beautiful yellow-red brown. They fall down on the people in the park, exactly like in the movies, and it is incredible.
At the end of the park, you will find Forta Sempione, which resembles Arc de Triomphe in Paris.
I believe it is one of the most beautiful parks in Milan.
Enjoy🤗
