Paul Grohmann, the geologist and palaeontologist Fritz Frech from Breslau and Georg Geyer from Vienna claimed the Kellerspitzen, shown on the Austrian map with a height of 2,813 metres, was the highest summit; the Italians Giovanni Marinelli and Arturo Ferrucci from the Italian Alpine Club, by contrast, favoured the Hohe Warte, which was marked on the Tavolette 1:50,000, Prato Carnico map with a height of 2,782.

According to German language literature the Kellerspitzen West Top was climbed on 15 July 1868 by Paul Grohmann, guided by Josef Moser from Kötschach and Peter Salcher from Luggau in the Lesach valley.

Not until 13 July 1878 did Giovanni Hocke of the Società Alpina Friulana (today the Udine Branch of the IAC), together with Adam Riebler, a master locksmith and mountain guide from Mauthen, succeed in conquering the East Top, which they reached via the Kollinkofel.

The crossing from the East to the West Top was first achieved on 29 August by the aristocratic brothers, Guido and Cesare Mantica, with their guide, Nicolò Silverio from Timau.

The region still has numerous remains of military positions and trenches; the old supply route between the peaks of the Kellerspitzen makes a crossing easy for today's visitors.
