A karst cave hotel art gallery is a unique type of hotel that combines the natural beauty of karst caves with an art gallery space. Karst caves are formed by the dissolution of soluble rocks like limestone, dolomite, and gypsum. These hotels are typically found in regions with extensive karst landscapes, such as China's Guizhou Province. The art gallery within the cave may feature contemporary or traditional art pieces, showcasing the fusion of natural and artistic elements.
