If you are visiting Hin Muang and Hin Deang, you would normally dive Hin Muang first as this site is the trickier and a little deeper site, or so it would seem. Yet they bottom out about at around 65/70 metres and on the seabed, they are actually linked.

These two dive sites are in the Southern Andaman some distance from the Similans they are extremely popular with Liveaboards from Phuket and day trip boats from Koh Lanta, Koh Lipe and of course, Phi Phi Islands here is also great for Dive Education Courses such as:

•    Advanced
•    Adventure Diver
•    other specialities


Situated 100 km’s to the south of Phuket (Chalong Bay) this site is a huge outcrop of massive boulders pushed up from the seabed over millions of years, coming to form one of the most talked about dive sites in the country.


Hin Muang translates to “Purple Rock” in English referring to the beautiful purple soft coral which covers the dive site.


The Hin Muang is approximately 200 metres long and 20 metres wide. The dive site runs from East to West. There are usually 2 mooring lines, with the most western one around 16 metres deep, the Eastern, 40 metres plus.

There are several pinnacles to explore on Hin Muang. At the Eastern end (the shallowest part) the site is only 8 metres deep which is the closest point to the surface. The Northern side of the site is the “shallow” side dropping off to around 45 metres. 

The Southern side drops off to at least 70 metres making this one of the deepest recreational dive sites in the country.

Currents can vary from moderate to very strong, but you can use the rocks as protection from the current just be careful coming off the main part of the site, as in a current you will struggle to get back to the safety of the boulders.

In between the pinnacles (normally at a depth of between 20 metres and 30 metres), there is a chance to catch a glimpse of large Stingrays resting on the bottom. Midwater you can expect to come across; Rainbow Runners, Barracudas, Trevallies, Snappers and Fusiliers.

Other fish on this site and similar to Hin Deang are Giant Morays, Puffer Fish, Porcupinefish, Trigger Fish, Angel Fish, Butterfly Fish, Box Fish, Surgeon Fish, Unicorn Fish, Turtles, Trumpet Fish, Wrasse, Groupers, Parrotfish, Sweetlips, Hawkfish, Octopus, Sea Snakes, Lion Fish, Scorpion Fish, Soldier Fish, Anemone Fish, Blennies, Nudibranch.

I remember this site fondly as it was where I saw my first ever Manta Ray’s there was three in total and I was working off a boat from Phi Phi Island. 

We travelled quite a long way and as we dropped in within two minutes of getting down there was a fly-by, by one huge Manta Ray and as it just melted into the background as the other two appeared. I had seen nothing like it before, to see these massive fish just cruising the seas so graceful and beautiful made it a day I will never forget.

Both Hin Muang and Hin Deang offer something different from each other and both are in the top five dive sites in the country and on their day they can be spectacular, attracting large pelagic fish such as Manta Rays and Whalesharks.
