Your kids may be glued to their iPhones throughout the flight (or car ride) to Utah, but once they spend a few minutes hiking the rose-orange dirt roads that criss-cross Capitol Reef National Park, they'll change their tune. Mammoth, jagged-edged rock formations shoot up into the sky. These wrinkles in the earth's surface developed tens of millions of years ago, and Google Maps doesn't do the dazzling scene a bit of justice. (Admission: $20 per vehicle.)
