Characteristic for Coral Caverns are the fossils in the limestone walls: stromataporoids, brachiopods, and horn corals.

At one time in the history of the cave, it was completely flooded and massive calcite crystals, which only form under water, were formed. These were later covered with a stalactite flow giving rise to some unusually shaped formations. The highlight of the cave is the 10 m high Cathedral Room, full of speleothems and limestone pendants. Practically no wall or ceiling is free of speleothems and many areas are coated with calcite to a thickness of 15 to 45 cm.
