Cavern Diving: A Beginner’s Guide

You’re gliding into a vast underwater cavern. In the crystal-clear water all around you majestic stalactites hang down from the cavern ceiling like icicles. Cone-shaped stalagmites rise up to meet them. Gnarled tree roots snake through the cavern’s roof to get a drink of water. But wait…you must be dreaming, because you’re only an Open Water-certified diver. You can’t possibly be exploring the inner sanctum of an underwater cavern, because this type of diving is suited for only those expert divers who’ve had a lot of advanced training, right?

My first off-the-wall experience was one I’ll hold dear forever.
