I live at Milan's outskirts and I love the big park that is between my town and the town next, San Donato, just before the city.
My favorite moment to be there is the early morning. There is hardly anyone, just a few people crossing the park to head somewhere. There is a small bar just in the middle of the park to enjoy a coffee or an ice cream in the summer. I love it how it is full of trees and home to rabbits and ducks. The path is 2 km long, great for clearing my head before starting the day.
