NEMO 33 . . .

NEMO 33 (The World's Deepest Swimming Pool)

The world’s deepest swimming hole, located in Brussels, Belgium. Nemo 33 is a submerged structure with platforms at various levels that plummet down 108 feet! It holds 2,500,000 liters of non-chlorinated spring water that stays a toasty 86 degrees. Divers often use this facility to train, and there are even simulated underwater caves! All-out awesome!
