Everyone gets to try things out at this "science playground for the whole family" where "please touch" interactive science and nature exhibits provide a fun and educational experience. The center is housed in a huge converted city power plant and includes aquariums stocked with walleye, gar, trout and other Missouri River fish.

Not your typical museum structure, this one is built into the side of hill, and much of it is underground. A contemporary version of a traditional Native American dwelling, this beautiful building features Native American (mostly the Sioux tribes) and pioneer exhibits, with many rare artifacts tracing the history of South Dakota.

A causeway connects downtown Pierre with this scenic island where only foot-traffic is allowed.
