BestUnique Hotels

Cave rooms, suspended treehouses, desert camps, ice hotels and underwater suites — properties where the building itself is the experience. Some are seasonal and deliberately simple; others pair unusual architecture with full resort comforts. In every case, check the room type and operating season before booking because the headline feature may apply to only part of the property.
