National Mississippi River Museum & Aquarium, Dubuque

Fun for the whole family great place buy the year pass saves money for Multiple trips. There's another larger building where you can feed the stingrays. New exhibit featuring otters! Huge aquariums great hands activities & educational fun. They have a huge metal workshop that was used to build boat engines over a 100 years old that still works. They have a craft room featuring 3-D printers

In the Smithsonian system this museum is top quality. A real steamer dredge is available to walk through. Lots of Mississippi fish in large aquariums. There are many excellent historical displays highlighting the indigenous people of the area and their ways of life. There is also an area with rotating Smithsonian system exhibits that rotate in and out. They also have outdoor areas with native wildlife such as otters and turtles. There is something here for everyone. Good stuff.
