Bobolandia

Located just north of the city centre, Bobolandia is the largest family amusement centre in Poland, offering 3000 square metres of fun and attractions. Pretty much every kid's dream, this family funhouse includes all kinds of plush and inflatable play areas and jungle gyms, trampolines, ball pits, slides, sandboxes, and more, plus pool tables, air hockey, and arcade games. There's also a restaurant. As you could probably spend all day here (and your child will no doubt want to), tickets are sold at a flat day rate of 55zł per kid on weekdays (40zł if you arrive after 17:00), 65zł per kid on weekends (50zł after 17:00). The nice part is adults only pay 5zł and are likely to have a great time also.
