Why should you go there and how do you do it right?

On Koh Tao, many things still work by booking directly over the phone. There's no website, no booking portal, just a phone number and someone on the other end of the line to discuss your wishes. Sounds complicated? It is. But the groups are usually smaller, and the guide adapts to the day's circumstances instead of always following the same route.

The main draw here is the water. Koh Tao's reefs and dive sites are the primary reason visitors arrive by boat from Chumphon or Surat Thani, and an island-based operator is ideally positioned to take advantage of these opportunities. Come with a clear idea of ​​what you want to do—whether it's snorkeling, a coastal cruise, or a longer tour—and ask directly. Vague questions lead to vague answers.

From February to September, the sea is calmest and the visibility is best – this is also the busiest time of year for the island. Therefore, it's best to book well in advance during these months.
