- Gran Serra or Gran Sertz - 3.552 m -

One of the most popular summits in the lower (Northern) part of Gran Paradiso Group, the Gran Serra grows up, well distinguished, from the ridge between the Herbetet and the Grivola: so its little subgroup is the transition zone between two very different kind of rocks (gneiss of Gran Paradiso and green rocks and limestones of Grivola)

It is a not small mountain, it is a big ridge between the Valsavarenche and the Valnontey (Cogne Valley), most covered by (easy) glaciers.

No difficult routes on this summit that can be climbed in any season, the only problem can be given by the rocks on the higher part when iced.
