To become a cave diver, you need certain requirements such as age, open water certification, and a minimum number of logged dives. It’s essential to progress through three levels of training: cavern, intro to cave, and full cave. Skills like buoyancy, good positioning, and awareness of surroundings are crucial. Finding a competent instructor and being open to feedback are important steps. Safety is key in cave diving, and having the right mindset can lead to safe and enjoyable dives.
