Unusual hotels

Chicago's Magnificent Mile has hosted many skyscraper hotels such as the Allerton Hotel.

Many hotels can be considered destinations in themselves, by dint of unusual features of the lodging or its immediate environment:

Treehouse hotels

Some hotels are built with living trees as structural elements, for example the Costa Rica Tree House in the Gandoca-Manzanillo Wildlife Refuge, Costa Rica; the Treetops Hotel in Aberdare National Park, Kenya; the Ariau Towers near Manaus, Brazil, on the Rio Negro in the Amazon; and Bayram's Tree Houses in Olympos, Turkey.

Cave hotels

Desert Cave Hotel in Coober Pedy, South Australia and the Cuevas Pedro Antonio de Alarcón (named after the author) in Guadix, Spain, as well as several hotels in Cappadocia, Turkey, are notable for being built into natural cave formations, some with rooms underground.
