Europe's Best Small Hotels
Courtesy of Treehotel
The Treehotel (doubles from $482), inspired by a documentary film about tree huggers, takes green to new heights. Suspended in the trees of a forest in northern Sweden, 37 miles from the Arctic Circle, the five conceptual retreats resemble, respectively, a cubic cabin, a flying saucer, a bird’s nest, a Modernist pinecone, and a mirrored box. Footbridges and viewing platforms above the Lule River valley allow guests to commune with nature. Even the birch sauna seems to float in midair.
