A picturesque spa town with rich historical architecture ranging from Gothic to Renaissance and Baroque, numerous sanatoriums, parks and gardens, including an arboretum, considered one of the oldest spa towns in Poland.

In 1949–1950 Greeks and Macedonians, refugees of the Greek Civil War, were temporarily admitted in Lądek-Zdrój, before new homes were found for them in other towns.
