The youngest mountain conquerors

The climb up Piz Badile took the family four days, with one night spent in an alpine hut and the others spent in bivouacs, which are small, metal sheds. From their valley starting point, it took five hours to reach the Swiss hut, then they camped out on a shoulder of the mountain before a big day of the more difficult climbing. They reached the summit on the third day, then descended the next on the Italian side of the mountain.
