Italy's Trail System Has A Difficulty Rating and Signage TRAIL DIFFICULTY A scale of difficulty for different mountain routes has also been introduced for hiking. It involves four distinct grades of difficulty: T: Tourist path. Easy path or forest road, not very long, very evident not posing problems with bearing. E: Hiking, Path without technical difficulties on variable ground, even rough and bumpy and at time steep; can sometimes include prepared crossings which do not require special equipment; most of the paths in the Dolomites belong to this category. EE: for Expert Hikers. Marked path, over more treacherous ground, at altitudes even elevated, with open stretches which call for sure footing and no dizziness. Prepared stretches call for the correct equipment (karabiners, metal friction plates, harness and ropes). EEA: for Equipped Expert Hikers. These are routes and prepared paths with frequent open stretches , difficult also because they are long

Passo Fedaia is a great climb and good challenge. The ride take you over the Marolada Mountain Group of the Dolomite (Marolada is the tallest of the Dolomite's) and past Lago di Fedaia, this is the site from the movie "The Italian Job", (where the guy double crossed the others).

There are two routes up to Passo Fedàia.
From Caprile (the most challenging route)
From Canazei
