Alms are alpine meadows where farmers can have their animals free-range graze all summer. In the days of my parents (and before them), cows, horses, sheep and goats were herded up to their alms in mid-June and herded back down in early September. Today everyone trucks their animals to and from the alm. Huts were built to provide rudimentary accommodation when farmers needed to be on the alm for whatever reason. Alms also had barns and most alms made cheese during the summer. My mom remembers herding the family animals to and from the alm and making cheese.
Today these huts are mostly rented out to tourists. No electricity, no running water, an outhouse and animals all around. This is the Paludnig Alm - the highest alm in this area.
