cave mouth
Grotto's front door
The opening of a cave—the point where the interior meets the outside world.
Cave mouths vary from narrow crevices to dramatic arched entrances: We spotted the cave mouth halfway up the cliff face.
The term treats the cave as a creature with the opening as its maw, fitting the sense of entering a dark, enclosed space.
