This is the longest tunnel on the greenway: it's super fun to go through. Be careful: it's a bit chilly!

Magnificent view of the historic center, with the river it makes a magnificent landscape. A bit of a shame that there is the main road not far away with the incessant noise of cars... but it's still worth it!
