If you're looking to grab a drink somewhere a little unusual, Atlas Obscura has just the thing for you. The site has put together a guide to "bars at the end of the world," including everywhere from a research base in Antarctica to a South African bar housed inside a gigantic, 75-foot-tall tree that could be as much as 6,000 years old. Its signature drink? "A beer from the literal root cellar and a can of ant repellant," writes Eric Grundhauser. Be sure to check out Atlas Obscura for the complete list, and start planning your vacation time accordingly.
