What to expect underwater
About 30 minutes north of Chalok Bay, Twins is one of Koh Tao’s most popular sites for beginner and fun divers.
Two pinnacles rise side by side, surrounded by coral gardens and sandy patches where you’ll see anemonefish, butterflyfish, and angelfish weaving through the reef.
The shallow sandy area between the pinnacles is a nursery for juvenile fish and home to stingrays, making it full of life.
