Passo di Praderadego is one of the main passes that connects the two sides of the Belluno Prealps, the Treviso side of the Valley with Valbelluna. At its peak stands the homonymous inhabited center, consisting of about twenty buildings (inhabited only seasonally) and the Ai Faggi restaurant bar.
According to one of the historical reconstructions on the subject, a variant of the Via Claudia Augusta Altinate passed through the pass, the route of which is traced by the CAI 1028 path. Confirming the strategic importance of the road, on the Belluno side stands the Castle of Zumelle. According to an etymological hypothesis, the toponym should be read as a compound (prà de radego) which can be translated from the Veneto as "meadow of the dispute": it would have been a disputed location or where people met to settle disputes.
