Caverns exist in many areas where scuba divers venture – from freshwater springs to volcanic island walls and limestone coasts. In these locations you’ll find large, dark spaces that seem incredibly inviting, yet are potentially dangerous. The Cavern Diver Specialty course gives you the knowledge and skills to explore caverns correctly – allowing you to enter far enough for adventure, but staying within the light zone for an easy exit to open water.

You need to be Advanced Open Water Diver who is at least 18 years old to enroll in the Cavern Diver course.
