Heading away on a diving holiday is likely to be extremely rewarding and allow you to see some of the most beautiful locations in the world in a fun, active and adventurous way. In turn, the chances of getting bored (as you might if you were simply sat on a beach all week) are almost zero, and the potential for adventure is great.
However, scuba diving also carries certain risks with it, and the last thing you or those you are with will want is to see your quest for fun and adventure lead to injuries, which may not only ruin an expensive holiday, but could also have many serious long term repercussions.
The first thing to do before you go diving for the first time is to talk to your doctor. Whilst the majority of people can enjoy such a pastime without any problems, there will be certain medical conditions that can complicate this, and furthermore you will need a certain level of fitness to get out of the experience what you should.
Another thing you should do before you go is to get travel insurance including scuba diving. Even those who are well versed in diving will face certain dangers beneath the water and ensuring that you can get the right medical treatment or repatriation in such a case will be integral, and without the right level of travel insurance diving demands, you could find yourself in metaphorical hot water.
Never try to dive without the right qualifications. No matter whether you have dabbled before or not, going with an instructor or waiting until you pass any relevant courses will be a must to ensure you are confident and able in the water.
Finally, know your equipment and know when to dive. Diving when the sun in setting is not recommended unless you have the qualifications to do so, and always be sure that you only go near marine life that you know to be safe.
