Koh Mai Thon is located 17 kilometres East of Chalong Bay, south of Koh Doc Mai. Koh Mai Thon is rarely dived which keeps the reefs around the Island in pristine condition. The east coast of Koh Mai Thon is home of the biggest coral plantation around Phuket. The waters are usually crystal clear with a powdery sand beach and resident wild dolphins that are regularly spotted here.
On the western side of the island is a rocky outcrop following the island. The rocks and reef run down to about 18 metres.
Mai Thon offers 6 dives sites in total and has a depth range of 2m to 25m. Koh Mai Thon has plenty of healthy hard corals, barrel sponges and sea fans to see. Additionally you are likely to see a few different types of Puffer fish, Moray Eels and Lionfish. There are lots of Nudibranchs as well as the usual tropical reef fish that are native to the region.
At the dive site known as Eastern Promise you will find a great selection of hard corals. Additionally there are a number of Whip corals, Sea Fans and Barrel Sponges. The coral begins as shallow as just 2m and continues down to the sand line at around 8 -10m. Eastern Promise has some nice sheltered sandy areas. Also for the macro enthusiast, Eastern Promise has a good selection of shrimps and Nudibranchs. Among the “special finds” you may be lucky enough to see a Honeycomb Moray Eel.
At Koh Mai Thon – South Tip the coral begins as shallow as 2m and continues down to the sand line at around 25m. This is a more challenging dive site than any other dive site around Koh Mai Thon especially as the currents can be strong here and there is very little shelter from the island.
If you head out South from Koh Mai Thon Island you will find a steep drop off which allows you to get to a moderate depth fairly quickly.
At South Tip reef itself, expect to see the usual Angel Fish and Butterfly Fish. There are also Puffer / Porcupine Fish, Moray Eels, Lion Fish, Scorpions Fish, Surgeon Fish and Wrasse.
Some of the more unusual sightings include Eagle Rays and the occasional Leopard Shark!
Windmill Bay, Hideaway Bay, No Name Bay and Radio Bay are all Mai Thon dive site on the Western side of the island. You will see that some of the hard corals grow up to 1m below the surface in places so you will have to look around a little before making your descent. The shallow waters close by the island are a good place to see squid. Further out into the reef you can look around for the rarer Tomato Anemone fish and if you’re lucky the fantastically colored Honeycomb Moray Eel.
All scuba diving dive sites are visited at the discretion of the tour leader on the day. Dive sites are selected based on the weather conditions, currents, overall safety and suitability for the majority of divers on the boat. We cannot guarantee specific dive sites prior to the boat departing.
