The first part is theoretical classroom training including diving videos if time permits.

You may be itching to jump into the water, but it is important to know this information first.

Later, you will practice the breathing techniques you just learned in a swimming pool.

Finally, you can then begin to dive into the open water to earn your certification.

Some Tips for Diving Tours in Koh Samui

1. Avoid booking a diving tour during the monsoon season between November and February; the usually calm, clear waters can get quite choppy and murky.

2. You can opt for an individual trainer but a group class offers the chance to make new friends who share your passion for diving.

You may be vacationing in Thailand with family or friends who are not interested in diving.

They can still accompany you on the diving tour in Koh Samui and enjoy peaceful snorkeling, swimming, or sunbathing while you explore the underwater beauty of Thailand.

Travel Insurance for Diving in Thailand

When planning a diving trip to Thailand, it is important to make sure you have the right travel insurance coverage.

Diving can be an exciting and dangerous activity, and if something goes wrong, you’ll want to be covered.

Travel insurance for diving should include coverage for medical expenses in case of an accident or injury while underwater.

It is also important to make sure the policy covers emergency evacuation if needed, and medical repatriation if necessary.

When considering a travel insurance plan for a diving trip in Thailand, you should also look into plans that include coverage for lost or damaged equipment while underwater, as well as personal liability coverage in case you accidentally harm or damage property owned by another diver or person while on your trip.

Check the exclusions of the policy to make sure it is not excluding coverage for diving-related activities.

Take care to read the small print and to ensure that any water sports such as diving that you plan to be involved with during your trip, are covered.
