What may be the world's only underground hotel presents a contemporary, blocky face to the desert town. In the 19 spacious, subsurface rooms, luxurious white and dark blue duvets complement and contrast the red-striated rock walls that protect sleepers from sound and heat. Aboveground rooms are also available. The hotel offers daily tours of the town and surrounding sights. The owners have another hotel, the Opal Inn (08/8672–5054 or 1800/088523 www.opalinn.com.au), where you can chat with opal buyers.
