This enormous park is the green lung of the city; it's also one of the largest enclosed parks in Europe, with some 295 hectares of bello bosco (charming woodland). It sits on the Lambro river and incorporates the Autodromo di Monza race course, a horse-racing track, a golf course, tennis courts, a 50m Olympic swimming pool and miles of cycle paths. You can hire bikes at the Porta di Monza entrance (€3 per hour).
