Which Bermudian cave is known for its crystal-clear underground lakes?

The Bermudian cave known for its crystal-clear underground lakes is Crystal Cave (Bermuda). It is part of the Crystal and Fantasy Caves system in Hamilton Parish, where mineral-rich water surrounds striking stalactites, stalagmites, and crystal formations.

The cave was discovered in 1907 after two boys lost a cricket ball through a hole in the ground. Fourteen-year-old Bernard Wilkinson was lowered about 140 feet with a bicycle lamp and found a subterranean chamber containing a clear lake roughly 55 feet deep. The cave’s formations began developing more than 30 million years ago as groundwater deposited calcium carbonate.

Crystal Cave also has a place in film history: it appeared in the 1913 Universal production Neptune’s Daughter. A common mix-up is confusing it with Fantasy Cave, a neighboring Bermudian attraction in the same cave complex. The names are related, but the question’s famous underground lakes point specifically to Crystal Cave.
