We went while it was raining and it was interesting to see how far the water had come up. Seems like it would be cool to attend a concert there but otherwise a little boring. We were in and out in 5 min.

A small and hidden jem, make sure you have shoes and good flashlight, the day i was there the museum was closed but all you need to do is follow the sign to continue to the mine. Several young performing artists were getting ready to put on a show and a photo shoot was also going on. A great place to have lunch and explore, wont need more than an hour. Also if your in the area a qick stop at the parking lot of high falls for a great vista. Finnally parking at the lot for the rosendale tressle and rail trail, you can cross the street and take a short walk on the rail trail to the trestle (go right once you get up to the trail, once you pass the tressle take the trail on the right that hooks around and under the bridge. A stop at the truss and trestle for a bite to eat should round off a great day. Enjoy

Maybe I was missing something and perhaps could have needed a tour guide. I believe they do tours on Sundays. I went in by myself and while it was spooky being in a mine, after it rained and water was dropping on me, there wasn't much to it. Go see it because the estate around it is nice but go when there are tours.

Loved this mine, It is so interesting and amazing. Better to bring a flashlight so you can get a decent look at the mine. Would go again.

I’ve come here many time with my friends and we always have a blast. There is the usual area that you see in pictures on google that is somewhat explorable but if you venture off to the side to these approximate grid coordinates (41.8415360, -74.0963730) then you will find the real fun. The entrance is large but not as big as the main area. In here you can travel far underground and be met with the cold air, darkness, a few bats and some exhilarating/one of a kind areas that are incredibly worth the exploration. Bring a couple high powered flashlights and some extra batteries just in case. There is no cell phone reception once you venture below ground. It is easy to walk and completely flat. You can probably venture at least a mile or so deep into the cave. There are remnants of an old mining company and their cables/machines. There is plenty of graffiti and there are even some abandoned buildings inside quite a ways down. The path will zig and zag a little bit and the farthest I’ve ever traveled was a little over a mile I think down to a spot where there is stagnant water. The sounds and overall feel of this gem of a cave is half of the excitement. I spent probably 3 or 4 hours down there exploring and investigating every nook and cranny possible.
