- One of Koh Tao’s greatest strengths is its versatility. Its many shallow, calm bays provide ideal conditions for beginners to comfortably learn the ropes and complete their first certifications. At the same time, more experienced divers will find plenty of challenges and thrilling encounters at deeper sites, including natural pinnacles and fascinating shipwrecks.

The waters surrounding Koh Tao are bursting with life. Divers can explore diverse coral reefs, home to a kaleidoscope of hard and soft corals. The reefs teem with colorful reef fish such as parrotfish, barracuda, snappers, and groupers.

- Professional Dive Schools
Koh Tao is home to an impressive number of highly professional dive schools. These centers uphold high standards of safety and instruction, employing experienced instructors from around the world. Whether you prefer PADI, SSI, or other certification agencies, you’ll find a reputable school to meet your needs.
