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.

  • This cave has a nice hour long tour filled with interesting facts and great tails about the caves history. The staff are very friendly and knowledgeable and answered all my questions wonderfully. I highly recommend taking a bright uv flashlight with because there is tons of calcite deposits that fluorescence beautifully.
  • Excellent! Cave is beautiful. Tour guide was knowledgeable and made a valiant effort to be funny. No special features in the cave, unlike the others we have visited but worth a visit.
  • Like many other reviewers said, the one hour tour fits the bill. the guides are very knowledgeable and make for a fun experience. You end up about 70 feet underground and it's quite damp, in fact you do get dripped on quite a bit. the temp is always 50, so bring a sweatshirt and wear shoes versus sandals. The ground is wet and there are small puddles. the cave itself is pretty good size with many rooms and connections - they do a good job of lighting it and keeping it safe to walk on. But remember, it is a cave and you will hit your head if you are not paying attention. This cave is NOT handicap accessible however, and if you have trouble walking up steep inclines and stairs, this may not be for you.
  • One of the best caves around. It was fun for both the kids and the parents. Remember that it is always cold in the cave, so dress appropriately.
  • 1 hour long tour. My first cave experience, really cool thing to do on a road trip. Our tour guide was great and charismatic. I think yours are every quarter hour (e.g. 3:00, 3:15, 3:30, 3:45). Gift shop to peruse before the tour, and there are other smaller activities on the plot of land.
