51 Most Romantic Places in the U.S.A.

"Those planning on popping the question can do so here with the aid of a larger-than-life stone. Crystal Cave is not a cave in the traditional sense, but rather the interior of the world's largest geode, discovered in 1897 by workers who were building a well. Today, you can tour the inside of the geode — whose walls are lined with crystals as big as 18 inches in length — on a visit to Heineman's Winery. The winery, located on the Lake Erie island town of Put-in-Bay, has offered tours of the cave on their property for more than 100 years." - Travel + Leisure Editors

Not a huge cave by any means. It does a circle around the stairwell you come down from. But the beautiful celestite formations are so magnificent, I was in awe the whole time. You also get a tour of the winery and a free cup of a wine of your choice or grape juice that are made there. Very awesome experience for a very good price! Def worth a visit if you are on the island.

We enjoyed the tour. The cave was much smaller than expected but with the added on winery tour, it was worth the price, which wasn't expensive. We enjoyed both tour guides.

Super cool experience especially for the price. Went to Put In Bay for the first time over this past week and was not disappointed. This crystal cave is a must see and is breathtaking in person. The tour guide was super fun and was very knowledgeable about the history of the cave. If you’re in the area I recommend checking it out - you might even get “cave kiss”! Also the winery is very neat and you get a grape juice or wine sample included in the crystal cave tour price.

Really cool cave that is essentially climbing down into a MASSIVE geode. The tour guide was friendly, knowledgeable, and fun to talk to. The winery tour was also great and again the tour guide was friendly and knowledgeable. The cave and wine tour is only $14 and includes a cup of wine or grape juice at the end. The gift shop is also great and the prices are very reasonable. Highly recommended.

The cave was wonderful. A bit smaller than expected. It's technically a cave, but it's really a giant geode. Still very cool, but not a full cave tour like I was expecting.

Very unique cave. It is small for a cave but when you realize that you are standing INSIDE a geode it adds to the experience. The staff was friendly and knowledgeable.

The people were nice, the tours were reasonably priced, as well as the merch. We are thankful we caught the last tours of the day! The history is really cool of both the cave and the winery!

The staff are very kind and informative. We took our teens with us and they loved it. The crystals are huge, and you walk inside of a giant one! Lots of fun! I definitely recommend going! When you get the winery tour it includes a free drink token, and kids can drink from the juices that they make! Our drinks were delicious!
