Monte Re di Castello, Alpine summit in Lombardy, Italy

Monte Re di Castello is a 2,889 m summit in the Adamello group, on the border between Trentino and Brescia. Two ridges meet at the top: the western ridge rises from Passo Dernal (2,577 m) over a 2,883 m fore-summit, while the northern ridge climbs from Passo della Vedretta di Sarviore (2,540 m). The peak overlooks the Lago di Malga Boazzo to the southeast and the Lago d’Arno to the northwest.

The summit lies on the border between the provinces of Trento and Brescia, on the watershed between the Oglio and the Chiese. Hunters probably reached it first while chasing chamois; surveyors followed in 1853. The first documented ascent was made on 24 August 1874 by Douglas Freshfield, Thomas Henry Carson, Francis Fox Tuckett and guide François Devouassoud. During the First World War the Italian army occupied the peak and mounted a gun and a searchlight there.

The name first appears as Recastel on a 1764 map of southern Tyrol. It combines re, from rio (stream), with castello (castle), likely referring to the castle-like shape of the southeast ridge. The summit also holds remains of First World War fortifications, where the Italian army mounted a gun and a searchlight on rails.

Reaching the summit requires mountaineering experience and specialized climbing gear. The approach typically starts from a mountain refuge in the area, and visitors should account for altitude adjustment and changing weather when planning their visit.
