It's a highly recommended spot for families seeking educational fun, though the planetarium's limited schedule requires advance planning.

"Great little museums and affordable gift shop--bought more than i thought i would. My favorites was the chemistry interactive exhibit and the archeology exhibit about S. Africa. Lots of dioramas about nature. Great campus as well. Will return to see the planetarium which is currently only open 2 Saturdays a month."

"Great little museum not known by many people. Took some out of town family for a little day trip & we all ended up learning a few things about our region & the critters within it. Very affordable & if you take your time & look @ everything you could very well spend a couple hours entertaining little ones. Don't forget to check out the gift shop on the way out.....you may find a little project to continue your learning!"

"We basically had the whole place to ourselves, as it was a weekday and the museum most likely is less busy due to covid. It was very nice, and there was a lot to see and read. All the taxidermy there is very good quality, and the scenes that the taxidermy are placed into are all very realistic (down to fake animal droppings haha).
You can tell that a lot of time went into creating the scenes and into research for the information. It was very enjoyable.
I loved the gift shop as well, lots of very interesting and cool items. we got crystal bracelets, soap, and a little plastic frog.
I would definitely go again, especially since they show different exhibits and do different things like that sometimes.
Go pirates! :)"
