It's a slower, more sustainable way to travel. You can reach the start of Italy's many trails by train or bus, and from there the journey continues on foot. You stop to take in the view, or simply to rest, then carry on towards your destination.
The Path of the Gods, which you can see in the photo, is one of the most famous trails in Italy. It links Bomerano (a hamlet of Agerola) to Nocelle (a hamlet of Positano), with breathtaking views over the Amalfi Coast, Capri and the Tyrrhenian Sea.
A trail I've walked myself, instead, is the Blue Path of the Cinque Terre, from Monterosso to Vernazza. The effort is repaid by a wonderful view over the Ligurian Sea, Monterosso and Vernazza — the latter appearing through the greenery at the end of the path, like a vision.
Then there is the famous route that connects the Apuan Alps to Emilia-Romagna, the Via Vandelli, created in the eighteenth century. It is a historic road about 170 km long, running from Modena or Sassuolo all the way to Massa on the Tyrrhenian Sea. It is certainly demanding: it takes 7 days on foot (2–4 days by bike or e-bike) and includes high-altitude stretches above 1,600 metres. I would love to walk it one day and take in the Modena plain, the Tuscan-Emilian Apennines, the Garfagnana, the Apuan Alps and the Tuscan coast.
