Mount RushmoreSummer is the prime time to get travelin' with the family. The temperatures are warmer, the kids are out of school, and thankfully -- gas prices aren't absolutely ridiculous this year. The best part of living in the good ol' U S of A? There's a whole lot of terrific terrain just waiting to be explored right here in our own backyard!

As kids get older, they become less interested in quality family time and more interested in, you know, the "cooler things." Which is exactly why you gotta squeeze in some of these classic road trips while you still can. Yeah yeah yeah, water parks, those are fun, and so are beach towns. However, there are a whole slew of historic sites, monuments, and American landmarks across the country that are a must-see for every kid as they get older.

Check out our list of 25 great places to take your kids to before they graduate high school:
