The Igloo Village in Kakslauttanen, Finland just made my bucket list. Each igloo has an all-glass roof with climate-controlled rooms perfect for laying down and watching the millions of stars and the Norther Lights put on a show.
Built from special thermal glass, the view stays clear even when the temperature outside drops to under -30°C. Every igloo is equipped with a toilet and luxury beds and, every evening, a hot sauna and a refreshing ice hole await you.
In addition to the glass igloos, the resort features snow igloos, a snow restaurant, an ice gallery with ice sculptures, and a snow chapel for those we want to tie the knot. In total there are 20 glass igloos and 60 beds in the snow igloos, and the snow restaurant provides seating for 50-150 people. Igloo Village starts its season each year between December and January, depending on the weather conditions, and stays open until the end of April.
