What Are the Best Koh Tao Diving Sites?

Koh Tao island is a much more tranquil and less visited island than Koh Samui, another great diving destination in Thailand, so you can expect a calm and more tranquil environment – littered with dive sites. The Jamahkiri Resort & Spa is a very elegant and relaxing place, but there are lots of top dive sites and other activities.

Dive sites on Koh Tao island at the Jamahkiri Resort & Spa include the following:

  • Chumphon Pinnacle: The Chumphon Pinnacle is an elaborate formation that allows you to swim into a small fissure, within its nooks and crannies you will see colourful anemones, eels and much more. It reaches a depth of around 30 m and blends a cave and safari dive in the most unique way.
  • Sairee Beach: Sairee beach is a spot for snorkelers and shore divers alike, as such it is quite suitable for beginners. Several shallow beach dive sites will not require any boat ride, meaning you can enjoy the rest of Sairee beach – such as nearby dive shops or simply relaxing on the beach between dives.
  • Southwest: The less popular but still awe-inspiring Southwest is a circular site made from granite blocks in a jaw-dropping pyramid formation. There is abundant marine life to see and also a more advanced dive route, which takes you a bit further out – but this part of the site has stronger currents.

Koh Tao is an important tourist destination in the Surat Thani province and offers fantastic scuba diving, but there are many other things you can do – this makes it great for non-divers too. With an outdoor pool, spa services, top restaurants and excursions to nearby tourist spots you will find plenty to do aside from diving.

What Types of Fish Can I See on Koh Tao Island?

For open water dives, for which you may have to complete an open water course to attend, you can see very large creatures throughout the Gulf of Thailand – most notably whale sharks. However, for less experienced shore divers and snorkelers there are still many other creatures to see that do not require advanced courses.

You can expect to see a wide variety of marine life including the following:

What Are the Diving Conditions on Koh Tao Island?

Much like the rest of the Gulf of Thailand, the conditions for swimming, diving, snorkelling and all other marine activities are very pleasant – with gentle currents and mild temperatures. This is thanks to the position of the island, sheltered by the country’s long and narrow westward mainland.

The typical conditions you can expect during your Koh Tao diving holiday include the following:

  • Temperature: Year-round water temperatures on Koh Tao island rarely drop below 29°C (which is 84°F), so it easily offers one of the mildest and pleasant diving experiences. There are some seasonal changes in temperatures but never very wide fluctuations.
  • Currents: Gentle currents are a boon for new divers in Koh Tao, but these are predominantly onshore dives, such as those near Sairee Beach. The Chumphon Pinnacle has some stronger currents but is still manageable. Other sites such as parts of the Southwest dive site will require experience.
  • Visibility: You can expect excellent visibility throughout much of Thailand and Koh Tao’s Jamahkiri Resort & Spa is part of the Green Leaf Foundation and Environmental project, which is dedicated to maintaining pristine environments in the region. Visibility in Koh Tao is typically 25 m or more.

If there are any issues that you have with your confidence in the water then you can easily take part in one of our amazing diving courses before you leave. We specialise in teaching all abilities the essential scuba diving skills they need for any type of dive – so if you have a dream dive experience you will not miss out!
