Is Koh Tao really just a scuba diving factory island? With over 70 dive shops and thousands of divers getting certified here every year, Koh Tao has built a reputation as the cheapest place in the world to learn how to scuba dive. But does that mean experienced divers should avoid it?
In this video, we dive three of Koh Tao's most famous dive sites — Southwest Pinnacle, Sail Rock and Shark Island — to find out whether Koh Tao deserves its reputation, or whether it might actually be one of the best places for scuba diving in Thailand.
As professional divers who have worked across Thailand, Indonesia, Australia and the Maldives, we're sharing our honest verdict on Koh Tao diving conditions in 2026, the conditions we experienced, the marine life we encountered and whether we'd recommend it to certified divers.
Whether you're planning a Thailand diving trip, researching Koh Tao diving, looking for the best dive sites in Thailand or simply wondering if Koh Tao is worth it, we hope this video helps.
We joined The Diver's Boat on their popular 3S trip, which included Southwest Pinnacle, Sail Rock and Shark Island.
This was NOT a sponsored video — we paid in full for our trip just like any other guest. However, after spending the day with them, we genuinely felt it was one of the best-value dive trips we've experienced on Koh Tao, and a good dive operation is always worth recommending to our subscribers.
