In ancient times, the inhabitants of Val d'Ultimo and Val Venosta often crossed passes to move from one valley to another. One of these is the 'Rontscher Joch', which connects Castelbello in Venosta valley with Valburga in Val d'Ultimo by the shortest route (path!). A few metres below the yoke, on the side of Val d'Ultimo, in a hollow, are the two Covolo Lakes. An ideal place to rest.
