School’s out for summer—which means the kids need entertaining. This year, instead of heading to the closest theme park, consider a more educational vacation. The 10 cities below boast some of the best learning experiences in the country; plus, they’re loads of fun for little ones. These facilities are more than just indoor playgrounds—they’re hands-on and high-tech, introducing concepts of math, science, literature, history and geography in such an active, engaging way that the kids will never suspect that they’re expanding their minds. Even better: Museums are usually less expensive than theme parks, and you’ll encounter fewer crowds. It’s a win-win for the whole family!
