I hadn't been to the Cave of the Mounds in about 15 years and it's just an interesting now as it was with my youngest kid. Our guide was excellent on about about 45-minute tour. We went on a day when snow was melting so that was a small amount o dripping water. There are some easy stairs that are spread out and the walking surface is flat concrete with a slip-resistant surface. It's a great activity in the water or summer because the temperature is about 50 degrees year round. In the summer there is a beer garden and walking trails. I highly recommend if you're in the area.

Of all the places I went on our Wisconsin trip, I feel like this one was the least egregious money grab. Maybe that's because it's far away from the Dells (about an hour). 4 of us went for 70 dollars. The staff seemed knowledgeable and into nature. It was cool to see. I'm not sure what weight the National Natural Landmark designation actually has, I feel like this may be a title that they assigned to themselves. It wasn't a national park, that's for sure. Regardless, it was interesting and enjoyable. If you are of the huddled dad masses yearning to breathe free (or at least cheaply) to escape the wilely clutches of the incessant Dells, this will offer some reprieve.

This place is great if you just resist all the ridiculously expensive extras they try to sell you. The cave is awesome. All the options for finding gems and breaking geodes are way overpriced. Just skip those. Do splurge for a black light, though. That can make the experience even cooler.

Although the cave is an extraordinary find, I can't highly recommend this tour. The staff was very friendly and knowledgeable. However, there is not a great value in the tour. It's a cave. Nice and cool. For the cost, it's not at the top of my list to recommend.
