World's Coolest Underground Wonders

Coober Pedy, Australia
If the Apocalypse happens, this southern outback outpost will be ready: half of its 4,000 locals live underground, a vestige of a post-World War I opal mining boom that saw newly arrived solider-prospectors sleeping in dugouts. That and daytime temps in excess of 120 degrees. (Coober Pedy takes its name from the Aboriginal phrase for “white man in a hole.” Seriously.) Stay in an underground hotel and explore restaurants, art galleries, and a church, all below grade. Venture outdoors to play a round of grassless golf and see desert landscapes made famous in Mad Max Beyond Thunderdome and Pitch Black.
