Oh, to sleep under the northern lights

Perhaps there's no better place to watch the northern lights dance above you than curled up in bed under the glass dome of a heated igloo here in Lapland, the northernmost region of Finland. There are other glass-domed hotels to choose from in Lapland, but the Kakslauttanen Arctic Resort, shown here, is the most famous. Visitors come to view the aurora borealis, or northern lights, and for various outdoor sports. There's cross-country skiing, snowshoeing, downhill skiing, dogsledding, and even reindeer-drawn sleigh rides to keep you entertained during the short winter days. Evenings are spent dining (yes, reindeer may be on the menu), warming up in the sauna, and for some, sleeping under the stars and the swirling, hypnotic northern lights.
