Arches National Park, home to 2,000 known natural arches as well as numerous spires, fins, windows and natural bridges, is a fun place to take curious kids. Even those under the age of 9. Why? At Arches National Park science is real. Here, kids can see, first hand, the effects of water and wind on the shape of the land. And geology isn’t the only natural science that comes to life at this U.S. national park. Potholes and biological soil crusts, two unique natural features, are home to living organisms and offer children, as well as adults, a peek at biology. Even jaded teens are sure to confess, ‘This is neat stuff!’
