What to expect underwater
Just off the northeast coast, this site sits below Koh Tao’s old lighthouse.
The slope of boulders, sandy patches, and vibrant coral gardens is covered in both hard and soft corals, with sponges, sea fans, and colourful branching corals creating a stunning backdrop. Among them, you’ll see wrasse, barracuda, damselfish, angelfish, stingrays, and even the occasional longfaced emperor fish weaving through the reef.
The marine life here is incredibly diverse, offering something new every time you dive.
