Firstly a preface: all training's good and especially overhead training where the environment's so unforgiving. Plus lots of practice.

Where around the world are dive locations where you must have the cave diving certifications to dive? For example in Mexico or Florida.

What level are these requirements, if any, what is the legal status of these qualifications?

N.B. "Must have" meaning that you can't access the site without showing a card to the "guardian of the site" or it's an actual legal requirement. For most places around the world there's no such thing; you can just jump in and take responsibility for your own actions, i.e. you're suitably trained and experienced for the dive being planned.

  • Do you mean "must have the cave diving certifications to dive in a cave" or "must have the cave diving certifications to dive anywhere"? – DJClayworth Dec 12 '18 at 22:39

Straight up the Answer is almost certainly NO, since unless there is some way of restricting access to a site, any person can put on dive gear and go dive without any experience/training. I am not aware of any countries with laws prohibiting scuba diving in any form except for reward (commercial gain).

The more acceptable answer is, whenever you enter any overhead environment most divers/dive clubs/dive schools will require you to have appropriate training and experience. In the Light Zone, which is defined as linear 40m taking depth and penetration distance into account, the requirements are less strict and less enforced.

There are several organizations teaching Cave diving courses and they normally offer a few levels depending on how far you wish to penetrate and the time you will spend underwater. On a basic level you will have a Cavern course(lightzone), Basic Cave and Advanced Cave course. But there are many variations and add on courses, like using underwater propulsion vehicles, decompression diving, etc.

All over the world you will find interesting overhead diving that requires more advanced training, if this is something that interest you speak to people that knows the areas you are interested in and that knows cave diving.

Some dive boats/tours/centres will have their own requirements based on local laws/recommendations/experience, so as ever check before you go! (Aravona)

(Let me just add that there are people doing dives on their own without training and without building up their experience gradually, this is not something I recommend at all. Many divers have lost their lives doing dives past their limits and their knowledge/experience. Spend the time to find a good instructor and learn the theory, the skills/drills and do the dives gradually. In the end you will be safer and have more fun.)

Wikipedia has a good section on cave diving and lists a number of cave diving spots all over the world. WIKIPEDIA - CAVE DIVING

    There's a bunch of different 'qualifications' run by various agencies. Generally there's a introductory Cavern level within the "light zone"; a junior and full cave certification (to dive to thirds, lines, jumps, etc.); then the various advanced cave levels including deco stage diving, DPV, CCR, etc. – GlennG Dec 13 '18 at 10:32
  • I like the answer and learnt a lot from reading it. However, I think it doesn't answer the question. – Paul Paulsen Dec 13 '18 at 20:30

    well not as directly as it could, I amended it – AquaAlex Dec 13 '18 at 20:49
  • no it addresses it a lot better, thank you! +1 – Paul Paulsen Dec 13 '18 at 20:50

Most caves and mines in Germany require a cave certification, and I assume they are all privately owned and locked.

  • Also heard the same for Belgium where most are 'closed', particularly the mines, and you need club affiliation to access. – GlennG May 17 at 15:05
