Depends on age and residency.. If you plan to see other stuff , buy a City Pass. Otherwise visit the website to find admission prices.
Not sure now. When we went, I think it is Adult $26 Child $18.
If you have time and want to visit other things in the area, I would recommend a City Pass
For Chicago residents is $20
Buy online and don't wait in the long line, we ignored that advice the first time and were kicking ourselves, you can not buy day of online either
If I remember correctly, $40 for adults and $30 for kids.
$33 for adults/$25 for kids
