The web site says Oct 14, 2019 is the last day they are open. "Our last day of operations this season will be Monday, Columbus Day, October 14th, 2019." Actually I was there yesterday myself. I heard them say October 15th. That was my initial answer but then I checked the website and it said October 14th. I guess I would trust the website, but it's odd that there seems to be several answers to the same question!
I was there yesterday and was told 11/3.
