If extreme and unusual diving challenges are something for you, then you should definitely try diving under ice. Ice diving is one of those scuba diving specialties that promises a very special kind of adventure because you'll be exposed to conditions and underwater beauty that few divers get to see. As a bonus, you'll also have the opportunity to play with your own bubbles under the ice surface. Pull out your PADI Ice Diver certification card and not only will you get instant respect, but there will be plenty of questions from other divers about what it's like to dive under ice.
You must be a PADI Advanced Open Water Diver and be at least 18  years old to take the PADI Ice Diving Specialty course.
