PADI Seashell Divers

Dive with us in Koh Tao

Already a certified diver ?

We offer two trips every day and as an advantage of diving in small groups, we are able to offer unique opportunities to do 'drop off', deep and night dives.
We also schedule our trips to avoid being on a dive site with too many divers.

For certified divers, our experienced Divemasters ensure safe, fun and relaxed diving around the island. Their knowledge and familiarity of the sites gives you the best chance to find and observe the varied marine life and ecosystems we have here around Koh Tao.

After the day’s diving our Divemasters are always pleased to log the dives and discuss and identify the aquatic life you have been seeing with the help of our marine life library.

We offer as well night dives on a regular basis

Start at 1000 ฿

Morning :      6 am to  10:30

Wreck diving & Night Dive

In 2011, a ship from the Thai navy ( HTMS Sattakut 742) was sank as a part of an aftificial reef project .Itis a great dive for levels Advanced Open Water and above, but more importantly it is 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 .
We organize as well regular night dive in one of the nearby dive sites, and especially on Twins or White Rock, which are great for that.
