The tower-like peak of Piz Kesch was reached for the first time on September 7, 1846, by Chr. Casper, Johann Coaz, J. Rascher, J.R. Tscharner. In 1864 the ascent was repeated by Francis Fox Tuckett and Fowler, with guides C. Michel and M. Payot. From the Platzli huts, located above Bergün, they reached in 3 hours a pass (3,008 m) on the ridge above the Vadret da Porchabella, overlooking the head of the Es-cha valley on the east. From this — called Porta d'Es-cha — they finally reached the peak in less than 2 hours. They afterwards descended in 3 hours from the pass to La Punt on the east side of the mountain.
