We have always loved visiting this place and there are so much to explore. One day is just not enough. Old Man's Cave, Upper Falls and Lower Falls is one day trip. There are other falls and other activities that you can do. Plus, you can stay and make memories. Particularly referring to this Visitor Center- it's a good helpful location, lots of option to load up on snacks and drinks. Purchase some souvenir or toys. Use restrooms and take some rest. Everything about this visitor Center is helpful and good for your trip. The parking is huge but still crowded. Walk to the Visitor Center is just about 2-5 minutes from parking. You can also learn about the history, process and timeline of the park, falls and cave. Plenty of things to do here.
