Scuba diving tour with 2 dives from Koh Samui to the deep dive sites Southwest Pinnacle and Sail Rock

The Southwest Pinnacle is a collection of pinnacles with a unique topo-graphical arrangement, many fish and giant fan corals.


The Southwest Pinnacle is a circular site of seven pinnacles which have the shape of mountains and a lot of granite blocks between. From Koh Samui we need a bit longer than one hour to arrive at this dive site. The biggest pinnacle starts in five meters, the bottom line is by 28 meters. The underwater boulders are home of great marine life such as Bat fish, Barracuda, Potato grouper, huge schools of Big Eyed Jacks, Trevally, Chevron and Giant Barracuda and King Mackerels. You will be diving amongst swirling schools of Rabbitfish, Snapper and Fusiliers.

On the morning of your tour, an air-conditioned mini bus will pick you up at the reception area of your Koh Samui hotel for transportation to the boat pier. Travel time to the Southwest Pinnacle is approximately 70 minutes. Relax on board of our spacious catamaran, custom-made to provide you with superior comfort and safety. Our boat offers spacious indoor and outdoor seating and two toilets for your convenience. Throughout the day there will be snacks, a delicious Thai style lunch, and beverages available.

During the journey, you will meet your PADI scuba diving instructor, who will brief you on the days’ activities. He will set up your scuba equipment giving you time to relax and enjoy the stunning scenery. Before arriving at the dive site, a ‘dive briefing’ will be given. With small groups of certified divers per dedicated PADI instructor, you are unlikely to find a diving experience like this anywhere else!

A complete days diving at some of the most beautiful dive sites in Koh Tao. Beautiful reef fish such as the butterfly and angelfish can be found here swimming amongst whip corals and between large barrel sponges. Discover the rich underwater life and vibrant reef fish, colourful sponges and giant corals and maybe even turtles! Watch as smiling parrot fish make the sandy beaches of the future and see golden trevallies hunting small fish whilst the red breasted wrasse stop at cleaning stations. Blue spotted rays and a large variety of nudibranchs can also be discovered at these sites. The “friendly” titan or yellow margin trigger fish can also be found on these dive sites in Koh Tao which always make for great holiday memories! Then for the last dive we go to Sail Rock which sits 15m above and 35m below the surface Sail Rock is famous for its natural underwater chimney swim through which divers can enter at 5 - 6m and exit at 16 – 18m. Marine life can be seen where ever you look. If there is one scuba diving trip you don’t want to miss, this is it. You may even get to discover the sites secret pinnacle too.
