Diving Koh Samui – Koh Samui Island is the most popular tourist destination on the east coast of Thailand and has been attracting visitors since the early 1970’s. The Gulf of Thailand has some quality dive sites. Most of the dives sites are close to Koh Tao and Koh Phangan. Day trips out of Koh Samui are basically not available unless you like to charter your own boat.

The highlights in the Gulf of Thailand are whale sharks which are frequent visitors in this area. You will find as well towering pinnacles, huge rock formations covered in colourful soft and hard corals and sloping reefs.

For most scuba divers the diving on Thailand’s west coast is better, but that doesn’t mean you cannot have a great time underwater around Koh Samui. Koh Samui is one of Thailand’s favourite tourist destinations and will continue to be, as you find here excellent hotels, resorts, beautiful beaches, night life and quiet retreats here.

Samui is a great place for a Thailand holiday, especially during the summer months when Thailand’s west coast diving destinations such as Phuket and the Similan Islands are in their rainy season. But as Phuket is easily accessible from Samui, you can add a short dive trip to Phuket without any problems.
