When You Constantly Push Your Limits You Will Never Reach Them

Crystal Lake Cave

The beautiful rock formations found inside Crystal Lake Cave are literally two million years in the making. The cave system has been described as an underground labyrinth of wondrous mineral formations.With every step you take through the cave you will see a wide range of pristine stalagmites, helictites, and rare anthodites. Crystal Lake Cave offers two amazing tours, through this underground wonderland. The first tour is the general tour, which is a 45 minute guided tour, on flat paved walk ways. This tour takes you past some amazing formations, including; the Swiss Cottage Roof, the Lop-Eared Dog, The Cliff Dwellers, and the gorgeous Lost Gardens! The tour is well lit, and is ran by friendly, expert guides.The second tour is called the Wild Tour, and for good reason. This tour is a spelunkers delight. Brave thrill seekers, are guided through unexcavated and narrow passageways. You will see sections of the cave that very few have seen before. This tour is done mostly on your hands and knees, so knee pads are needed and a hard hat must be worn. The tour lasts an hour and a half and is perfect for the more adventurous members of your group.The Crystal Lake Caves gift shop is packed with all kinds of mineral-related keepsakes, and the kids will love the Mining Sluice, where they can uncover precious gemstones, fossils, and other hidden treasures using water and a sifter.

With two different tours to choose from, and a beautiful sheltered picnic area, Crystal Lake Cave is the perfect destination for your next family Adventure! The cave opens in May and closes again in mid October.We recommend calling and checking hours before planning a trip.

  19. Planning our trip here August 5th! #Excited

  20. We recently visited the cave, it was smaller then we had visioned, but it was beautiful! The tour guide was great, and I even bought some jewelry from the gift shop. We had such a fun time. Thank you for the information, we love your website and check it every weekend to see what fun adventure you will send us to next.

  21. Absolutely beautiful cave thank you for sharing this, we had a wonderful time!

  22. We decided to stop by on our way back to Chicago, its a little off the beaten path, but well worth the trip. My kids are already wanting to return. Nice article!

  23. We had such a great time on the tour, the picnic area was a little dirty though, over it was a good experience.

  24. Wow, this place is beautiful can’t wait to visit.

  25. This was the highlight of our trip to Iowa. Thanks for posting this.

  26. I had visited when I was a child, and had completly forgotten about the cave. Thank you for the article it was like a blast from the past currently planning to visit with my grand kids. Thank you.

  27. We had a wonderful time, cool history on the cave and the gift shop was nice too, thanks for sharing!

  28. Can’t believe they charged me to get inside, your article never mentioned any fee. This was bogus, we drove an hour to get there just to get charged an entry fee. the cave is beautiful but come on, it should be free.

    • It’s a business and they have a ton of overhead, if they did not charge, the cave would not be open. Sorry for the confusion, did not mean to mislead anyone with my article.

  29. Planning our visit this weekend, can’t wait!

  30. This cave is much smaller then the pictures show, still a beautiful cave though

  31. We really enjoyed our visit, and we even panned for gemstones. Thanks for sharing this cave with our family.

  32. Love visiting this cave, one of my favorites!

  33. We are planning a visit to Galena next month, guess we will have to hope across the bridge into Dubuque and visit the cave. We love this site and all the adventures you write about.

  34. Visited this and spook cave this year, both where cool caves but crystal lake cave is amazing. cool post

  35. Beautiful cave. nice article!

  36. Hi! This is my first visit to your blog! I love that you feature Midwest locations/adventures. We are going to the cave next weekend, and plan to visit some of the other Iowa locations before summer is over. Looking forward to visiting all the locations you write about.

  37. Took the kids last weekend, had a great time!

  38. Really enjoyed our visit, had no idea caves like this existed. Thanks

  39. I used to work here during H.S. great family owned business and cool show cave.

  40. We thoroughly enjoyed our visit, thanks for the information!

  41. Please explain to me why these caves think its okay to charge admission. Do us a favor and lose the tour guide and the fee, and this place would be a whole lot better. Don’t get me wrong the cave was beautiful, but its part of nature and nature should always be free.

  42. We are visiting tomorrow and I can’t wait

  43. Very informative piece you got here! Sharing this page on my news feed. Love this site, wish I had more time to visit some of these places.

  44. Do you work at the cave? We want to hire a guide to take us through.

  45. We want to visit next weekend, do you know of any camping locations nearby?

  46. Hoping to visit later this month.

  47. Pretty cool webpage, love that its all close to home. Visited the cave yesterday on our way to davenport. We had a nice time, the tour guide seemed new but the cave looked great.

  48. I don’t usually comment on these sort of things, but after reading that guy complaining about the price of admission I have to say something. First off you have to pay admission, because its a business. Do you understand how a business works? I’m sure the cave has a lot of over head, guides, electricity, advertising, staff. Do you think all of this comes free? I for one am glad to give my money to a place like this. This is small business, they create jobs, and provide a fun family experience. Look around at the wild caves in Iowa, none of them have crystals like this. That’s because they have a staff to make sure no one breaks and takes them home. Quit complaining on someones blog about a small business trying to earn a buck. For anyone reading this, the cave is well worth the price of admission. Sorry for the long rant.

  49. We took a visit on sunday I think you are our guide beautiful and fun cave tour. Thank you for telling me about your blog i will be sharing mine very soon i have great pictures to share with you and everyone. Very good blog post coming soon.

  50. Beautiful cave and very good article too.

  51. We really enjoyed meeting you and touring the cave, thank you for this great website!!

  52. We had a fun tour and took several beautiful pictures. Thanks for the recommendation.

  53. We took our cave tour and had a good time, but it left me wanting more. Along our tour we came across several passageways that have not been explored. Is it possible I could plan a visit in full spelunking gear, and explore these sections of the cave. I would even help map them out for you.

    • Hi Raul

      Thank you for reading and thank you for visiting the cave. Crystal Lake Cave offers a wild cave tour, through the passages that you are talking about. They require a reservation to book this tour, you can make that be calling the cave office. If you are looking for something beyond that, then you will need to call the cave and talk to Julie.

  54. I will have to make plans to visit! Well written.

  55. По заказу клиента мы нашли автомобиль который его интересовал
    По заказу клиента мы нашли автомобиль который его интересовал по запросу продать тойоту рав4, продать тойоту рав 4, продать тойоту рав4 киев . Договорившись о встрече с продавцом мы с клиентом приехали на осмотр автомобиля . После небольшого технического осмотра, стало понятно , что автомобиль находится в надлежащем техническом состоянии, за исключением нескольких царапин на кузове и небольших потертостей салона которые с легкостью можно было устранить.Указав на эти недостатки, продавец опустил цену на их устранение, и окончательная цена устроила нашего клиента. В итоге мы купили у клиента новую модель рав 4 (Истрия описана тут) ,и помогли подобрать необходимое транспортное средство которое хотел клиент, в итоге он остался с автомобилем и необходимыми средствами для бизнеса и все остались довольны

  81. Spent the weekend in Galena with my wife and decided to take a drive to see the cave. 2 things really surprised me on our visit. The size of the cave was unbelievable much bigger then anything at the State parks. Second the cave has some beautiful formations inside. Never see these at Maquoketa Caves or any other wild caves in the area. Very impressive.

  82. Beautiful cave and friendly staff.

    • They do not have camping, but the mines of Spain is really close. Yes they offer a group discount, just not exactly sure what it is. You will have to call them and speak with Julie.

  179. Друзья, пожалуйста, помогите ребенку! Не проходите мимо!
    Когда Эмир родился, он не заплакал и даже не задышал. Врачи допустили ошибку в принятии родов. Малыша перевели в палату интенсивной терапии в роддоме. На 3 сутки перевезли в реанимацию при 1 детской городской больнице Казани. Там родителям сказали, что ребенок очень тяжелый и даже при хорошем уходе проживет самое большее до двух лет, что лучше будет от него отказаться. Мальчику уже 7 лет, он живет и счастлив рядом с мамой и папой. Наблюдается, пусть и небольшая, положительная динамика. Родители Эмирчика стараются, как могут, сделать все, чтобы облегчить его страдания. После очередной сложнейшей операции ребенку требуется дорогостоящая реабилитация, но у родителей, к сожалению, нет таких денег, и они вынуждены обратиться за помощью к добрым людям. Пожалуйста, не проходите мимо чужой беды!

  180. took a visit while stateside a fine cave in iowa rich with history and wonder
