National Mississippi River Museum and Aquarium

350 East 3rd Street


The Dubuque County Historical Society (DCHS) has its roots in the Richard Herrmann Museum of Natural History, established in the 1870s. The DCHS was formed in 1950 as a private, non-profit organization with a focus on oral and archival history; and it opened its first museum, the Mathias Ham House, in 1964. Over the past 25 years the DCHS has successfully raised $54 million to organize and expand its Mississippi River Museum into the National Mississippi River Museum & Aquarium. The Museum & Aquarium is accredited by the American Association of Museums — a distinction held by only 9 percent of American museums, was named an affiliate of the Smithsonian Institution in August 2002, and was accredited by the Association of Zoos and Aquariums in 2009.

For the river lovers and kids at heart. Lots of information about the river - lock and dam, floods, wing dam and how the commercial goods came to be shipped via the Mississippi! They also have aquariums with an assortment of fish and other animals that live in or near the river. They also have a live hawk and eagle on display! A great quarter of a day to walk around and see things and interact. They have a small place where there are kid activities! A small snack bar and free refills on your beverage!

Had never been here before. Kids loved it! Lots to see and do. One thing outdoors was the electric boats that can be operated on a small pond (they use tokens which are available at the machine next to the boats. $1 = 1 token). Kids enjoyed that too. Got a membership and plan to go again!

Your ticket is good for two days, and our family spent a few hours there both days. So much to see and do! Our 3, 7, and 9 year olds were consistently engaged. I wish we lived closer because I would love to visit again!
