The Andaman Sea, on the western side of Thailand, is home to some of the country’s most famous dive spots. Islands like Phuket, Koh Phi Phi, Koh Lanta, and the Similan Islands are known for their vibrant underwater ecosystems. Divers can explore a kaleidoscope of marine life, including colourful tropical fish, majestic manta rays, graceful whale sharks, and even occasional encounters with gentle giant turtles.
The Gulf of Thailand, on the eastern side, offers equally mesmerising diving opportunities. Koh Tao, often referred to as the “Turtle Island,” is a popular destination for diving certification courses due to its calm waters and abundance of dive schools. Koh Samui and Koh Phangan also boast excellent diving sites with healthy reefs and diverse marine species.
Thailand’s diving scene is also committed to marine conservation, with many dive operators and organisations actively involved in protecting the delicate marine ecosystems. Divers can contribute to preserving Thailand’s underwater treasures by choosing eco-conscious operators and following responsible diving practices.
