This unique adventure, can be your "Dive to the Center of the Earth." Bonne Terre Mine, a national historic site, is the world's largest fresh water dive resort. Water conditions remain constant year round with over 100 foot visibility. Sights include: mammoth architecture, cal falls, oar carts, scaffolding, grating, staircases, pillars, slurry pipes, the famed elevator shaft, and much more. Bonne Terre Mine is without a doubt one of the most unusual, beautiful, and relaxing full service dive resorts anywhere. Your accommodations located in the rolling foot hills of the Ozark mountains are elegant at the nearby 1909 Depot, or if you prefer a more casual atmosphere, the Divers Lodge, located at the Mine.

The Billion Gallon Lake is illuminated with over 500,000 watts of lighting, a total of twenty-four dive trails have been laid out in the lake, taking the diver through mammoth archways, past beautiful calcium falls, around gargantuan pillars and to the man Depths of the dive tours average between 40 to 60 feet. Divers are toured through the mine in groups, of up to, ten by two specially trained dive guides. Super 80 cubic ft. aluminum tanks are provided each diver. Dive lights are not permitted in the lake, because they detract from the natural beauty of the illuminated surroundings. Power inflator are required on all BC's. The Billion Gallon Lake is 58 (Degree F) and not affected by outside temperatures, there are no thermoclines. Air temperature is 62 (Degree F) year round. Lighting on the rock formations is spectacular. One can descend to 80 feet and look up to see divers silhouetted against a rainbow. Man carved pillars grace the entire Billion Gallon Lake. The 200 foot solid-rock pillar rising from depths and mining artifacts on the walls and floor make for spectacular underwater photography.

Because of the wide range of dive trails offered at Bonne Terre Mine this trip offers something for all experience levels. From newly certified divers through to advanced technical dives can find Bonne Terre exciting and challenging.
