Want to see fish up close, see bees at work in an actual hive, listen to the calls turkeys make, or take a nice stroll through the woods? This nature center on the north side of Cape Girardeau should fit you need.
The center, which charges no admission, has lots of hands-on things to do, such as touching animal furs, learning about nature interactively with computers, crawling into an oversized beaver house, or seeing what kind of lures attract what kinds of fish. There is emphasis on what not to do in nature, as well, and how to best see nature and preserve it for the future.
The center has an open-glass area, complete with supplied binoculars, so that you can birdwatch, or look at butterflies or any other critter that happens up, from the comfort of a chair. There is a video to watch, and groups can have workshops here, plus kids (and kids only) can fish in a lake directly in front of the center.
Overall, I found this place to be very informative and not boring. Some of the exhibits were a bit confusing to work (and one was out of order), but no place will be totally perfect. The nature walk outside can be broken up into certain areas, or in a perimeter walk over a mile in length.
The center is not open on Sunday or Mondays, as is very easy to reach. Get off I-55, at Exit 99, onto U.S. 61 South. The entrance is about 1 mile south on the left.
