Mount Rushmore is one of those quintessential places every American should visit. At the base, a visitor center features a movie explaining why those presidents are included, along with a display that explains the process of building the memorial. The center is packed with memorabilia that includes letters from presidents, newspaper clippings, old photographs and descriptions of the conditions workers endured. An extensive gift shop allows you to purchase your traditional Rushmore souvenirs, and a snack shop overlooking the mountain offers one of the most inspiring ice-cream stops you'll ever make. Stick around in the evening for a patriotic ceremony featuring the lowering of the U.S. flag, recognition of visiting veterans, a patriotic film presentation and the lighting of the monument. Admission is free, but it'll cost you $10 to park.
