First time taking my family here. I loved coming back with them since visiting with my parents 25 years ago. The $10/car cost to visit is well worth the price. Start at the visitor center and catch a shuttle to the Lower Town. Plan on at least 6+ hours to really see and experience all their is to see and hike. If you have Children be sure to stop at the information center and ask about the Jr. Park Ranger program that is available at every national Park for little or no fee. It really helps kids of all ages to understand why the park is important. It also gives you a good idea of what to see and do while there.
