4 Most Unusual Hotels
2. Digging the Dug-Out
The Australian outback is filled with opal mines and dugouts galore—so dive in and experience one first-hand at the Desert Cave Hotel located within the sandstone of Coober Pedy. The hotel boasts 19 underground rooms, and about 30 rooms above ground for those who prefer not to live troglodyte-style. Also underground are casinos, shops featuring locally mined opals and Aboriginal arts and crafts. Rooms are about $150 a night, not including meals or a cave tour.
