In 1912, two boys in Bermuda’s Hamilton Parish lost a cricket ball. While searching for it, they discovered an opening into a previously undiscovered subterranean cave, one of many in the area that links Harrington Sound to the Atlantic Ocean. The one they stumbled across dwarfed the others, however. After exploring and swimming with just a lantern to guide them for hours, they scrambled back up to the surface. When their landlords, the wealthy Wilkinson family, heard about the cave, they investigated opening it to the public. Today, after excavation, renovation, and preservation, it is a major tourist attraction in Bermuda known as the Crystal Cave (another nearby cave was found at the same time, and is a linked attraction known as Fantasy Cave).
A few shots from the cave itself are below.
