The Bonne Terre Mine is a unique destination in Missouri. The mine was named after the small town it is located in and means “Good Earth” when translated from French. The mine is bigger than the town it is named for, consisting of 5 levels. The lower three levels combine to form a 17 mile long underground lake. This crystal clear lake is perfect for SCUBA diving and is the only inland SCUBA resort in the country.
The billion gallon lake, located completely underground, offers tourists a chance to experience the mine in a most unusual way. For those that do not like dive, you can take boat tours of the lake. The water is so clear that you can see 100 feet down at any given time.
The top two layers of the mine can be toured by foot and visitors can see what it was like to work in a lead mine 100 years ago. This mine opened in 1860 and continued to produce lead for over 100 years.
The Bonne Terre mine is perhaps most famous for its diving. It is the only inland SCUBA resort in the country, and of its kind. Many adventure seekers come here to experience the cool, clear depths of the water. Jacques Cousteau is perhaps the most famous person who enjoyed diving in this lake. National Geographic has also voted the Bonne Terre mines as one of the top 10 adventure spots in the country.
Divers can opt for one of the many dive packages offered at the resort. Children under 18 are allowed to dive if they are certified and have written parental permission. All divers are required to be certified to dive in the mine and log books will be kept.
The mine is open everyday during the summer months, and on the weekends only during winter. Depending on the weather, October business hours may vary.
