Koh Tao
Koh Tao is one of Thailand's most popular dive destinations, with excellent value for money. It is located off the coasts of Koh Samui and Koh Phangan, and can be reached by boat from either island.
Many people have come to this location specifically to complete their dive certification. It's difficult to find a better site to learn to scuba dive than here, with low course rates, easy conditions, and spectacular dives. Not only does Koh Tao diving provide excellent opportunities for beginners, but it also provides excellent opportunities for experienced scuba divers. It is an excellent site to learn new skills and increase your diving levels, and it has a solid reputation for dive schools.
Dive spots can be found all across the island and are only accessible by boat. There are numerous colorful reef fish, turtles, and barracudas to observe, as well as crabs and nudibranchs for macro items. If you're lucky, you might even get to swim with whale sharks.
