Treehotel Bird's Nest
Hidden in the boreal forest of northern Sweden, the Treehotel offers several unique tree suites built to blend into their woodland surroundings, including this enormous bird's nest perched high in a tree. From the outside you might think some winged giant wove the jumbo twig-like structure. But once inside (guests enter via a retractable staircase) it's all about human luxury. The roomy, modern living area and bedrooms are paneled in wood with windows offering stunning forest views.
