What is the primary purpose of cavern diving?

The primary purpose of cavern diving is to explore underwater caves while remaining in daylight zones and maintaining direct access to the surface. This type of diving allows divers to experience the unique environment of submerged caves without the increased risks associated with deeper cave diving, where complete reliance on artificial light and extended penetration into the cave system are required.

In cavern diving, divers generally stay within a certain area illuminated by natural light, which is crucial for safety and navigation. This practice is particularly important as it allows divers to maintain a safe escape route in case of an emergency while also enjoying the unique geological formations and the ecosystems found in these environments. The design of cavern diving specifically emphasizes the safety measures needed to help divers fully appreciate and explore these underwater environments while utilizing the natural light provided by the open entrances of the caves.
