Crystal Lake Cave is a Tourist Attraction, Souvenir Store, Gift Shop, & Tourist Attraction Cave located in Dubuque, Iowa and has been servicing all of Dubuque and the surrounding areas for many years. We specialize in Tours, Gem Mining, RV Parking Grounds, Tour Guides, Cave Tour Guides, Cavern Tour, and more! In 1868 lead miners drilled 40 feet into the ground to find traces of a rich lead vein. In this process they found very little lead, but instead discovered a natural geological wonder of matchless beauty. In 1932, the late Bernard Markus, (one of the original lead miners), opened the cave to the public, naming it Crystal Lake Cave. Today, Crystal Lake Cave is the longest "living" show cavern in the state of Iowa, and growing everyday. Don’t hesitate to give us a call at (563) 556-6451!
