TBH the adjective is superfluous by definition!
'Cavern' is usually applied to a very large, usually natural but sometimes artificial, subterranean chamber.
Sometimes it is applied to an entire cave system, especially if part of it is opened up for tourists - e.g. Carlsbad Caverns, Kent's Cavern.
It tends not to be used in formal speleological writing: it is a 'chamber' whether of 10m3 or 1000m3 volume.
A cavern is an underground chamber formed by erosion
its at the place where there is a long dive spot
Two features formed by underground weathering are caves and sinkholes. Caves are formed by the dissolution of limestone or other soluble rocks, creating underground chambers and passages. Sinkholes are depressions in the ground that form when the roof of an underground cavern collapses.

An underground cavern is a large cave or chamber typically found beneath the Earth's surface. These formations are often created through geological processes such as erosion, dissolution of rock, or volcanic activity. Underground caverns can contain unique ecosystems and geological features.
