It gets slightly more difficult as it goes south, but the only section which might present difficulties is the descent from Schiara, and this can be bypassed.
A typical day on the route might involve about seven hours walking, with ascents and descents of about 1000 meters.
The best period for hiking the trail is between late June to the mid-September when the route should be largely free of snow and the refuges are open.
The Alta Via 1 passes by several Via Ferrata, but none are incorporated in the route, and no special climbing equipment is required.
There are a number of other high-level routes in the Dolomites, including the Alta Via 2, which runs from Brixen to Feltre.
