Take the most popular entry-level diver course in the world.

If you are an explorer and haven’t spend more time underwater than a short snorkeltrip, then it’s time to get started!

Ever wondered, what it’s like to breathe underwater? To have fish swim around you and watching coral closely without having to think about the next breath you can take?

If you’re an explorer or just like nature and wildlife or want another challenge: the PADI Open Water Diver course is the perfect base to start your adventure.

In this course you will learn all the basics of safe scuba diving including dive theory and the skills you need, first in a shallow swimming pool followed by some amazing dives in the warm tropical waters of Koh Tao.



You will be accompanied and instructed at your own pace by one of our multilingual Instructors, who will teach you from the beginning to the end to get your PADI … and make some new buddies along the way.

We teach all courses at your pace, which makes it the perfect holiday experience!



Within 3 – 4 days, you will become a diver to dive independent from a professional to 18 m (60 feet) with a dive buddy! … Here is what you need for it:

To become a scuba diver, you don’t need to be an athlete or hardcore fit. You just need to have the passion and be open-minded to try something new.

It will help, if you generally feel comfortable in the water and have some basic swimming abilities (as there is a little swimtest as well). If in doubt, just ask us <Contact link>.

To start your course, you will need to be at least 10 years old* and be medically fit for diving. <download medical link>. If in doubt, please check with your physician or ask us <Contact link>.

(*As a diver 10 – 15 year old you will gain the certification as a Junior Open Water Diver. You will have to dive with an adult until 15 years of age. 10-12 year old divers are limited to 12 metres of depth.)

This is how we teach you diving! …:

Depending on your personal schedule we will adjust the program for you and move elements of your personal course to accommodate for your holiday plans, but in general these are the parts of your training:

We will start off with an introduction and a look at all the necessary paperwork. Once we have done this, you will start with the first part of your course: the dive theory. In some videos accompanied by self study you will get introduced in the basics of diving. After your self-study part, your Instructor will walk you through, how this theory is actually used in real-life diving and answer any questions you may have. The theoretical part is split into 5 chapters with a little quiz and an exam at the end (which you won’t be able to fail …).

We usually split the theory over two half days to make it less “dry”. If you really don’t like spending time of your holiday learning theory, check out the PADI Elearning-Option <link to elearning>.


The second part of your course is the training in one of our own resort  swimming-pools. Here you will learn all the skills, you need everyday as a diver as well as a few safety procedures, just in case of the unlikely event that something goes wrong.

You will start in very shallow water to take your first breaths underwater to slowly progress into the deeper end of the pool to practice on skills like swimming underwater weightless. Here is the place to take all the time it takes you to gain the confidence you need, so at Crystal Dive we don’t set a time for you to practice your skills. Usually it takes between half a day to a full day to reach the goal.

Once you gained your confidence and knowledge, it is time to get out to use all this on the final part of your course: the Open Water Dives.

The PADI Open Water Course consists of 4 Open Water Dives spread over two half-days. The first two of these will bring you to a maximum depth of 12 metres and give you plenty of time to practice skills and your underwater swimming, which you learned in the pool before. The final two dives are more for you to enjoy the underwater world and show us, that you know, how to dive independent from a professional!

After this you can call yourself an Open Water Diver and it is time to celebrate your certification with a cold drink on the beach!
