Open daily from 9 a.m. to 7 p.m. ( in autumn till 5 p.m.); greenhouses open from 10 a.m. to 6 p.m. (on Fridays greenhouses are closed). Krakow's Botanical Garden has a long tradition. It is now the oldest garden of this type in Poland, as it was set up in 1783, in the times of Enlightenment – time fostering the development of all science. Its location at 27 Kopernika street, a ten minutes’ easy walk from the very city center, is a best-kept secret of Krakow's traffic-weary residents.
