Crystal Cave, Spring Valley

#8 of 57 in Nature in Wisconsin
Crystal Cave is Wisconsin’s longest known cave. Crystal Cave located in Wisconsin's Pierce County, less than a mile west of Spring Valley on State Highway 29. Discovered by accident in 1881 by William Vanasse, Crystal Cave is a multi-level solutional cave formed in dolomite bedrock located in the Prairie du Chien Group. The dolomite was formed approximately 485 million years ago in the lower Ordovician Period when a warm shallow ocean covered much of Wisconsin and Minnesota.OverviewThe cave is accessed by a series of steps and ramps that allow visitors to descend over 70 feet. Stalactites, stalagmites and rippling flowstone can be seen hanging from the ceiling or covering the ledges of the cave.During the school year, the cave is a popular destination for tourists and school field trips.

  • Our oldest (tween) didn't want to go. She had a lot of fun. The tour is very informative. It can get chilly down in the cave. I would bring a hoodie if you get cold easily. If you have a child that is...  more »
  • Cozy place, with a super guided tour of the cave. The wizard was good to tell about the cave and there were more things to see down there with its history. Outside, you can buy the possibility of children to wash sand and find its own stone.

  • Friendly and enthusiastic guides lead tours into the cave, which is large and beautiful. Along the tour, one learns about the history of the cave and the geology of the region, hears a whimsical story, and gets to see lots of bats. I won't ruin the best parts of the tour, but suffice to say, it's worth the money. There's also a cute little gift shop topside, which sells beautiful (if a tad overpriced) rocks and trinkets.
  • Nice little side trip. Enjoyed cavern, nice gift shop and pleasant tour with a good guide. Walked grounds and talked with folks from different places.
  • A little pricey for a walk in the cave. But then it depends on your guide. We had a good one who made the walk lively! Don’t forget your jacket irrespective of the season you visit the cave. It’ll always be cold all through the year.
  • I really enjoyed this place. Our tour guide Calvin was great, the cave was awesome, and the kids loved it. I might have had the most fun! I would highly recommend this as a family excursion. Make sure and grab a bag of gems that the kids can sluice at the end of the tour. Wisconsin's longest cave!!!
  • The tour was educational and fun. It kept us engaged. This is worth the side trip to see. There is a place to take a picnic lunch and relax outdoors with the family.
