A fun, interactive, education park for kids named after local sci-fi author Stanisław Lem. This 6 hectare 'science garden' features over 100 different stations engaging kids in a wide variety of topics related to the laws of physics, including optical illusions, acoustics, gravity, magnetism, mechanics and more. Getting a serious upgrade in 2021, the park now has more exciting hands-on exhibits than ever - including multiple slides, swings and even a bicycle on a tightrope. Basically a giant educational playground, there's also an aromatic herb garden, greenhouse and small planetarium showing 5 different films. A nice change of pace from modern multimedia museums, preschool up to middle school aged kids - as well as their parents - should all have a great time here. The explanations at each station are in English and Polish if you can get your kids to slow down enough to pay attention to them. Be prepared that some of the most exciting attractions cost extra, and there is also an ice cream stand and food cart selling crepes. Reserve 90 minutes to visit the park in its entirety and get there via trams 1, 14 or 22, getting off at the 'M1 Al. Pokoju' stop; alternatively, a cab from the centre is about 25zł.
Note that this is a seasonal attraction and open from mid-April until mid-October.
