  • Very nice museum and displays. The quite outside answered all our questions. Learned a lot, and enjoyed the stop. You can see ships up close.

  • I visited as a child on a field trip and didn’t really take everything in. (I was more into World History and Geometry...) Anyways, my partner and I love museums and exploring the area and finally made it back to the Melvin Price Lock and Dam this past weekend. It was a neat experience and though we didn’t get the normal tour due to construction, we still enjoyed our time and will be back in the Spring! Hunter was very intelligent and informative with the tour and his knowledge of the history and other Lock and Dam locations throughout the Mississippi River. Aside from the tour, the museum was well kept and clean. We both tried the simulator and that was amusing. We spent a little over an hour there in total but it was a cool, gloomy day. I think we will stay longer next time and walk around the path/pavilion outside to watch some barges and boats go through.
  • Great experience and tour!!! We learned alot about the Mississippi river.
