So we went down the way we had come from on Friday, unfortunately we had to go through the Tunnel again with the car and were terrified that a car would come from the other side, because loads of people were going up towards the valley, it was Saturday and perfect weather after loads of bad weekends. We were lucky though. However, after parking the car at the beginning of Lago Luzzone we had to walk through another long tunnel. I walked through it four years ago, on my way to capanna Motterascio. I didn't enjoy it then and I didn't enjoy it today. See the photo, the tunnel is 833m long, dark (even though there were lights) get and cold.
