I’d give this a 3 star during COVID but it’s probably closer to a 3.5 star post-COVID if not a 4* for kiddos!
The grounds themselves are OK; not much to look at. The bathrooms were old and a bit dirty. The ghost town is walking distance through a short cut or you can quickly drive over to the parking lot.
I wouldn’t recommended visiting during covid. There were only a few gift shops open. I just wanted to grab an expensive beer and sit outside on one of the patios and that wasn’t an option. Everything from the train to going into the mine was not available. Mostly understandable, but still, it would have been nice if there were socially-distanced, safe food or entertaining options. You can just walk around the town right now.
