Trust the Austrians to make this dream a reality. The Starkenberger beer pools were created by the Starkenberger Castle’s brewery located in the tiny town of Tarrenz. The beer pools (or Bierschwimmbad, if you want to use their proper name) are rented, private hot-tub-size beer pools for up to four people. You can choose your own bathing temperature! Not only is this every frat boy’s fantasy, but according to the brewery, the vitamin-rich beer is a veritable fountain of youth. Prost!
