What distinguishes cavern diving from cave diving?

Cavern diving is characterized by its proximity to natural light sources, distinguishing it from cave diving. In cavern diving, divers operate within an overhead environment that is still illuminated by external light, such as sunlight filtering through openings or entrances. This illumination allows divers to maintain a visual connection to the surface, which enhances safety and orientation while navigating through the cavernous spaces.

Understanding this distinction is crucial for safety and proper preparation. In contrast, cave diving typically involves completely submerged environments that lack natural light, requiring divers to rely entirely on artificial lighting and advanced navigation skills. These factors emphasize the increased levels of training and experience needed for cave diving compared to cavern diving.
