As far as traditional points of interest, rather than the big-name attractions, I’ve found the more enjoyable times to be at smaller museums and parks that I’d never heard of. (I prefer museums where you can take your time and actually see everything in an hour or two, rather than getting overwhelmed and exhausted in gargantuan collections.) Finding out about these places on my own may have added to my enjoyment; I didn’t have any expectations. (So, reading about them here may spoil the surprise for you. Sorry.) I’m not sure that I would recommend driving halfway across the country just to visit any of these destinations, but if you happen to be in the area, here are a few that stood out:
A.E. Seaman Mineral Museum, Houghton, Michigan
Fenimore Art Museum, Cooperstown, New York
Museum of Women in the Arts, Washington, DC
Fairbanks Museum & Planetarium, St, Johnsbury, Vermont- hands-on science exhibits, lots of taxidermy, plus a mix of natural and historical objects traditionally found in museums
Land Between the Lakes, Kentucky/Tennessee- There were about 5 different campgrounds dotting the length of the park. In addition to hiking trails, beaches, and typical campground activities, this park offers a driving loop where you can see bison and elk, a planetarium, a nature center, and an 1850s working farm.
Elephant Rocks State Park, Missouri- gigantic rocks that you can climb all over and hike on. This would be a great place to bring kids!
Women’s Rights National Historical Park & National Women’s Hall of Fame, Seneca Falls, New York (two separate museums)- inspiring stories of women who were pioneers, exceptional in their field, involved in public life, started organizations, started social movements, etc.
Anyone with kids should check out City Museum in St. Louis, Missouri- The entire place is a huge indoor/outdoor playground, creatively and artfully constructed. It’s also insanely crowded.
Mille Lacs Indian Museum, Onamia, Minnesota- and next door is a gorgeous (albeit pricey) gift shop
I’d also add the attractions along Route 90 in South Dakota, described in this previous post.
