Lots of fun for the kids! This old industrial unit in the port area has been cleaned up and dozens of industrial strength trampolines have been installed. The whole area is quite large, close to the size of a football field. There are different areas, each safely netted off from the others and most importantly the ground, so you can throw yourself into the fun fully without fear of flying off. Perfect for a rainy day and kids' parties! You buy tickets for periods of an hour, starting at 12:00 (last at 20:00). Also, find them in Gdansk at ul. Grunwaldzka 355.
