Cavern Diver

If you dive within the light zone of a cave, the area near the cave entrance where natural light is always visibly, you're cavern diving. If you want to explore secrets hidden in caverns around the world you'll need your PADI Cavern Diver certification.

What do I need to start?

  • PADI Advanced Open Water Diver certification
  • Minimum age: 18 years old

What will I do?

During your first open water dive you'll practice line handling, reel use and emergency procedures without entering a cavern. But, for your next three dives, you're headed into the cavern, staying within the light zone and 40 metres/130 feet total distance of the surface.

You'll also cover the following:

  • Planning, organization, techniques, problems and hazards of cavern diving.
  • Special equipment use, such as lights, guidelines, reels and redundant breathing systems.
  • Proper body position, buoyancy control, air management and emergency procedures.
  • Cavern diving hazards such as silting, line problems, disorientation and emergencies.

How long will it take?

  • Recommended Course Hours: 24
  • Minimum Open Water Training: four dives over two days

Where can I go from here?

You can apply this Specialty course towards your Master Scuba Diver rating.

To search for adventure contact your local PADI Dive Center or Resort and sign up for your PADI Cavern Diver course.

* This is not a cave diving course and does not result in a cave diving certification. It does prepare you to enter a cave diving program.

Become a Master Scuba Diver?

Show off your training and knowledge by receiving the Master Scuba Diver certification. This is the highest recreational diver level in the PADI system of diver education. It indicates you have received a significant amount of training and experience in a variety of dive environments. Completing this specialty brings you one step closer to achieving this sought after certification.
