The mine’s statistics are impressive: dating to the 13th century, the salt mine at Wielkiczka is 327 metres (1,073 ft) deep and over 287 kilometres (178 mi) long. The tour itself covers probably one or two percent of that distance, though, and it only goes down to the first thre levels. That doesn’t really lessen the impression it makes: tunnel after tunnel leading to spaces carved from salt that seem impossibly tall or wide or both.
And on a rainy day — once it starts raining in Poland, it seems there’s a 100% chance of days of rain — there’s probably nothing better to do.
