Southwest Pinnacle (Kong Tong Ku)

A favorite with many of our customers (and staff!), Southwest Pinnacle is a 50 minute boat ride out to sea, and as such attracts pelagics and schooling fish in abundance. One minute you can be swimming alongside the giant groupers that patrol the deeper parts of the dive site, the next you may find yourself in the company of hundreds of barracuda or even, if you're lucky a whale shark

HTMS Sattakut

Lies approximately 40m south of Hin Peewee with her bow facing Northwest, Sitting upright. The top of the wreck is around 20m and and the bottom is at about 32m. When it was sank as a part of an aftificial reef project last year the wreck landed on its starboard side in a different location to where it is now, It was only after a few months that its position was corected and was put back upright that more and more people started to dive there. Now it is one of the most popular dive sites on Koh Tao.

This is a great dive for levels Advanced Open Water and above, but more importantly a perfect training dive for technical diver training, and as it is a very open wreck with lots of entry and exit points it makes a good training wreck for courses such as PADI Wreck Diver and TDI Advanced Wreck courses
