We are St. Louis' only complete dive center since 1960. We offer everything you need for the ultimate diving experience. Dive Bonne Terre Mine this weekend! Open water training is the most important aspect of becoming a certified diver. The conditions that students are exposed to during their first dives should be nothing short of excellent. Bonne Terre offers such excellent diving conditions that 15,000 certified divers a year flock to West End Diving's "Billion Gallon Lake Resort" to participate in the adventure of diving the mine. Winter or Summer, West End Diving can guarantee our students 100 plus feet of visibility and a constant 58 degree water temperature. These prime conditions allow students to concentrate on perfecting newly acquired skills.
