Hin Daeng Liveaboard Diving

Location: Thailand Thailand

Hin Daeng (Red Rock in the local language) is one of the best diving sites in Thailand. It’s not suitable for new or inexperienced divers.

Hin Daeng’s Remote Location is Perfect for The Marine Life

Being located far from any land or islands and surrounded by deep-sea means that Hin Daeng is a haven for hundreds of species of marine life, including hundreds of thousands of individuals. Most species spend their whole lives here, but larger fish visit Hin Daeng to find food or to be cleaned. The sea all around is deep for many miles, meaning that nutrient-rich cooler water supplies Hin Daeng with everything it needs to become and remain a healthy marine oasis. The water is usually very clear & clean as well. The peak of Hin Daeng almost touches the surface at low tide, and all of its sides are covered with lots of corals, especially red & purple soft corals. This is most likely how it got its name. There is something for divers to see at depths from just a few metres below the surface all the way down to more than 50 metres, which is deeper than recreational scuba divers are able to go to. Different species can be found at different depths, and these include lots of interesting bony fish & invertebrates. Divers at Hin Daeng need to look out for life within the corals and rocks but at the same time keep an eye out for something large that may visit.

These larger fish are often seen at Hin Daeng but never guaranteed. Because it is far away from everything else, not many scuba diving boats visit Hin Daeng. Daytrip boats usually come from Phi Phi, Koh Lanta or Phuket, but the best way to dive at Hin Daeng is to come by scuba diving liveaboard. Not only does this enable you to dive more than twice, you’re guaranteed to be there when the day trip boats aren’t there for your early morning and sunset dives. Also, Thailand liveaboard diving boats that visit Hin Daeng only do so while on a ‘Southern Andaman cruise’ and not on a Similan liveaboard trip. This means that very few boats are at Hin Daeng on most days, and it’s likely that there’s only one. Also, just 200 metres away from Hin Daeng is Hin Muang, an equally-wonderful dive site with a very deep & steep wall. When compared to places like Richelieu Rock that are always full of divers, it is really nice to dive at Hin Daeng.

Hin Daeng is an undersea mount. It's a limestone pinnacle that comes from the deep seabed and almost touches the surface at low tide. On more than one of its sides are steep walls, covered in hard & soft corals.

Where is Hin Daeng?

Hin Daeng is located in Thailand's southern Andaman Sea. The nearest island (Koh Rok) is 25km to the east. The mainland (Trang) is 60km east. Also, 60km away is Koh Phi Phi to the north, and Phuket is 90km northwest. With no land or other islands anywhere near, there’s no beach to visit or anything to look at during your surface interval. Also, there is no protection from any wind or waves, meaning that the surface of the water can be a bit choppy.

How to get to Hin Daeng

Who can dive at Hin Daeng

PADI Open Water + Adventure Deep 30m, PADI Advanced Open Water, SSI Open Water + Adventure Deep, SSI Advanced Adventurer, CMAS 2, NAUI Experienced equivalent or higher. Minimum 20 logged dives.

Although there are no official rules saying that new, inexperienced or Open Water divers can't dive at Hin Daeng, it's not practical for them to go there. The conditions* require experience, and in nearly all cases, the other divers in your group or on your boat will be certified deeper and have more experience. Therefore, it's not fair to hold them back with shallower or shorter dives.

* Being located in open sea means a high chance of waves at the surface. The exposed location means currents can be strong and unpredictable. The deep and clear water encourages divers to descend to 30 metres or sometimes deeper.

What marine life can you see at Hin Daeng?
