This place is totally cute! Went here with nephew and brother today as a kid-friendly activity; the nature center is a mixture of taxidermy animals and live animals on display, hands-on activities, and a nature walk that leads to a park. Most of the displays are in good working order, but a couple could use some repair.
Tips:
1) Kids over 2 years have to pay admission, which is currently $6. Not bad for what you get.
2) The live animals are really neat, but many of them get startled by loud noises and banging on the displays. Please make sure your kids are respectful of their space.
3) There is a space for kids' parties; why not plan a Birthday party for your animal-loving kids there?
4) if you don't want your kids to get dirty, don't take them on the nature trail/park. The park is great and has lots of fun activities, but is a mulch-and-dirt based area with wood chips and other forms of nature. :-) I personally thought the teepee and chimes play areas were cool, and my nephew loved the child-sized wheelbarrows.
5) If your kids love this place, get a membership. They last for a year and will pay off in three or four visits, depending on family size.
