Cima Altemberg, Mountain summit in Province of Vercelli, Italy.

Cima Altemberg is a mountain summit in the Pennine Alps positioned between two alpine valleys and reaches approximately 2,400 meters in elevation. The terrain features alpine meadows and rocky formations that make the summit accessible via several hiking routes.

The mountain name comes from Walser German, combining words meaning old and mountain, reflecting historical Germanic settlements in the region. This linguistic connection shows the long-standing presence of German-speaking alpine inhabitants in this area.

The name Altemberg comes from Walser German: Alten means old and Berg means mountain, so it can be read as "old mountain". Walser settlers colonised the upper Strona valley, and the toponym preserves their language. The summit is marked by a metallic cross.

The summit can be reached from two directions: via Campello Monti in the Valstrona valley or via Rimella in the Valsesia valley, with each route offering different lengths and difficulty levels. A metallic cross marks the summit and serves as a clear landmark.

On the summit stands a metallic cross, a detail many hikers only notice on arrival. The ridge linking the Altemberg to Cima Lago, crossed via the Bocchetta Stretta pass, is rated PD and calls for climbing skill. The peak lies in the Parco naturale dell'Alta Val Sesia e dell'Alta Val Strona.
