Koh Tas


Koh Tas is an island about 1 hour from the mainland which currently has very little development and is fringed with reef. It has two main beaches on the north and south side, the rest being rock that goes down to the sea.

The best diving around this island is to the west and south and tends to be relatively shallow going to a depth of around 8-9m. Visibility ranges from 5-25m but is usually around 10m.

1. Koh Tas North
This dive site has coral reef from the shore which drops to a shallow sandy bottom at around 9m. There are many coral bommies and an abundance of juvenile fish life. You should also expect scorpionfish and moray eels hidden around the corals.

2. Koh Tas West
A favourite site, this is characterized by rocks at the water’s edge which drop off, gradually at the south end and sharply further north, to a sandy bottom at around 14m. From the shallows, there is a proliferation of dazzling coral and fish life. At the south end there are many anemones, box fish, large parrot fish and schools of yellow goat fish. Further north at around 12m there are sea bass, large snappers and sweetlips.

3. Koh Tas South
This dive site features beautiful shallow coral reefs and bommies from the shore which drop to a shallow sandy bottom at around 7m and gradually goes deeper to the west to a maximum of 12m. There are many brilliant anemones and an abundance of fish life. This is a great dive for macro-life and also for snorkellers and try diving.
