Igloo Village Kühtai
Kühtai sits above two thousand metres in the Tyrol, which is why an igloo village can be built there and left standing for a full winter. Crews arrive in late autumn, blow and pack snow into domes, and carve the interiors out once the shells have set.
Sleeping rooms are snow chambers with an insulated mat, a sheepskin layer and an expedition-grade sleeping bag; some are plain, some are carved with reliefs cut by hand into the walls. The temperature inside holds a few degrees below freezing whatever the mountain is doing outside, which is the entire trick of snow construction.
Evenings run to a hot meal, a whirlpool set in the snow under the ridge line, and a guided walk before bed. Heated buildings with showers and lockers sit alongside the village, so the cold is a decision you make for the night rather than a condition you are stuck in. By May none of it exists.
