Have you ever woken up and thought to yourself, “I wonder where 8% of Europe's gold originated from in the 16th century?” If you answered yes to this question, prepare to be blown away.
In the small southwestern town of Zloty Stok, a former gold/arsenic mine turned subterranean exhibit gives visitors a first hand look at a major source of Polish wealth over the centuries. We're aware that this information on its own may not be enough to sway you, but it turns out this mine holds a unique secret: the Zloty Stok waterfall, a colorfully illuminated 9 meter (30 ft) cataract that runs underground and is the only one of its kind in Poland. Book an available subterranean boat ride and you'll complete one of the most unusually rewarding tours available in the country.
Location:Town of Zloty Stok, along the Czech Republic border, southwest Poland
Note:It should be noted that the mine and waterfall, rewarding as they may be, aren't really the kinds of experiences you'd want to travel vast distances just to catch in a lifetime. If you happen to find yourself in southwestern Poland, however, they'll certainly add some intrigue to your itinerary.
