Have you ever wondered what it might be like to live under the sea? Imagine the feeling of freedom you would have swimming through the clear, blue water deep beneath the waves, admiring the different types of corals, unusual plants and the creatures that call the sea bed home. Passing turtles are swimming above you, while bright and colorful groups of fish are travelling alongside you through the depths. All of this is possible on one of our scuba（水中呼吸器）-diving holidays!

International Diving Tours can prepare you for the experience of a lifetime. On our scuba-diving holidays, you will have the opportunity to swim in some of the most beautiful locations in the world, where you can explore underwater caves and coral reefs, and witness some of the strangest and most wonderful creatures on the planet. Not only will you have one of the most exciting times of your life, but you will also come back from your trip feeling calm and relaxed.

We offer several different holiday options for you to choose from. Our sales people can plan and organize the best trip for you, all for the best price! Options include the chance to explore some of the most famous ancient shipwrecks hidden beneath the ocean, or, if you prefer the natural world, we also offer tours of the world-famous Great Barrier Reef in Australia. We even offer the chance to swim with dolphins or venture into a shark cage, where behind the safety of a metal barrier you can watch these fierce beasts go about their daily life.

All the necessary equipment for your underwater adventure is provided, from wetsuits designed to fit all body shapes, to the latest scuba masks to help you see when you are exploring the world beneath the sea. For longer dives, we provide tanks of oxygen that can let you dive for up to four hours. All of our equipment is checked regularly to ensure that you remain safe at all times.

Our instructors are among the best in the world. They will show you how to swim in your scuba equipment and how to communicate with hand signals under water, which is vital for deep-sea diving. They will also make sure you understand how to return to the surface safely, since rising too quickly can cause a number of health problems. Most importantly, however, they will make sure you have fun.
