Mount Rushmore is one of those places everyone should try to get to. There is a charge to get into the park (it is for parking, but if you're OK with walking there are places to park for free). It is an amazing experience to see the heads. There is a pretty impressive gift shop on the premises. Also, the restaurant has a huge selection of food and it is a most wonderful experience to dine with the heads in the background. They do offer a 9 PM lighting of the heads, but it is long and there is not much to it.
