Monte Sasso is located in the western part of the Spina Verde Park.
If you love contemporary history, you should go for the trenches and tunnels of the First World War, created to prevent a potential German invasion from Switzerland.
You can get there in approx. 45 minutes by following the road that starts from Via per Bronno, within the municipality of San Fermo della Battaglia.
Before getting there, you will come across the viewpoint of Pin Umbrela, that offers an amazing view of Lake Como.
A few minutes away from the trenches, you can also find the springs of Seveso River, which runs for 52 km (32 miles) until it gets to Milan.
