How long does it take you to walk a mile? Plus there's two informative videos they play in the visitor center. I'd say an hour or so if you really look around and read everything. If all you do is want your NPS passport stamp: 5-10 min. But that's not really the whole point is it?
I'd say a minimum of 2 hours. They have a new movie at the Visitors Center+ a second movie & the little museum. Then walking the course down through the woods & the drive through with stops at the cabin etc. Leave enough time to really enjoy what is there!
Really depends on how long you want to stay. You can see everything in 20-30 minutes. We've spent 30 minutes to a couple of hours.
About 20 minutes. There is not much other than the visitor center and a bunch of land. There is one of house, that we saw driving.
