Kakslauttanen Arctic Resort

Glass igloos built for watching the Northern Lights from a horizontal position: that's the premise, and the resort commits to it completely. Most guests actually stay in log cabins with observation domes attached, which means a private sauna and a skylight view rather than sleeping in what is, technically, a snow globe. Husky safaris, reindeer treks, snowmobiling, and cross-country skiing fill the days, with a full outdoor program running through summer too.
