Some people think you must go to the beach or an amusement park during summer vacation, but the really cool destinations are caves. Cool, both literally and figuratively. Temperatures deep underground stay in the 50s both winter and summer and you don't have to wear sunscreen. Besides, caves contain fantastic geologic formations that teach you about earth science while you are sightseeing. About twenty years ago, I took my kids on the longest tour at Mammoth Cave that was open to children. They never got hot, tired, or bored. Even staying in a cabin with no AC was pleasant. There are no mosquitos at Mammoth Cave National Park because the ground is porous and the water table is low. And there are bats.
While I am quite proud of Kentucky's (and America's) biggest cave, there are opportunities to tour caves all across the contiguous United States. And they don't require steel-toed boots or crawling on your belly- just a light jacket and sometimes a reservation.
