As some of you might know I hiked the Sentiero Italia (over 3,000 miles) through the Alps and Appeninnes in Italy last year. I took my 10 year old daughter for most of it. I adapted a bit of the trail to suit my desire to see some of Austria and Switzerland as well as parts of Italy. The trail connects all of Italy East to West and North to South including Sicily and Sardinia. It was wild, fun and very tough. I’d compare it to the CDT for constant route finding (actually much more so) but like most European journeys, resupply and a bed are always pretty close.
Here is a few minute clip of the long journey. https://m.youtube.com/watch?v=XlTqS4ST3VE
Some people call this hike the Grand Italian Trail
