Niagara Cave

Ever want to get married in a very tiny chapel underground with huge waterfalls? You can here. My five-year-old and I had a lot of fun on the hour-long tour of the cave. I love rocks so the gift shop was fun. You can pan for gold and other rocks if you buy bags of rocks from the shop and run them through water outside. That was interesting and enthralled my child. There's a playground, and a large mini-golf course that we didn't try but looked fun. I'd recommend bringing snacks, and maybe a future spouse if you want to get married and have fewer than ten guests. We drove 2.5 hours each way and would do it again.

One of the more wet show caves in the area, the running water is definitely a highlight. There's only one type of tour offered, and it takes roughly an hour. Unless you're a fan of putt-putt, there's not really anything else on offer besides the cave itself.

Niagara Cave's latest planned feature is an 18 hole mini-golf course. "Coming soon!"

We hope the course is inside the cave, not out by the parking lot. June 2017: Tipster AR writes: "It's out by the parking lot." April 2019: Photo added.
