Put this one on the bucket list. Just over a thousand feet below the ground lies ‘one of the most valuable monuments of material and spiritual culture in Poland’ – the Wieliczka Salt Mine. While mining has halted in this salt mine (it stopped producing table salt in 2007), this place is still as popular as ever, thanks to an “underground amusement park” of sorts, including grand halls, health spas and accommodations. If you’re feeling particularly adventurous, Wieliczka is holding an 80s themed disco party come New Years.
