Diving Hin Daeng & Hin Muang

Mu Ko Lanta National Park

Hin Daeng (Red Rock) and Hin Muang (Purple Rock) are two famous rocky pinnacles located in deep water at the far southern fringes of the Mu Koh Lanta Marine National Park.

The hard and soft coral condition at both of these dive sites is excellent, providing a home to a huge abundance and diversity of marine life. When diving around Hin Daeng and Hin Muang, we can often spot many species not normally found at the other dive sites around Koh Lanta.

Sitting far from mainland Thailand, Hin Daeng and Hin Muang are important cleaning stations for pelagic marine life, including Giant Oceanic Manta Rays and Whale Sharks, which we may see passing by at certain times of year.

These dive sites are in open seas, and whilst most of the time conditions at these dive sites are great, conditions can sometimes be challenging. We recommend divers have recent experience of deeper diving in stronger currents.

For less experienced divers, we recommend taking the PADI Advanced Open Water Diver course, which can include a trip to Hin Daeng & Hin Muang after the first day diving.

Diving Hin Daeng & Hin Muang from Koh Lanta on our fast boats means shorter journey times, later departures, and earlier returns to Koh Lanta. Typical journey times are only 60 - 75 minutes by speedboat from our office at Lanta Castaway Beach Resort.

Hin Muang

Hin Muang (Purple Rock) is located only a few hundred metres away from Hin Daeng. The top of the reef starts at a depth of around 12 metres and drops down to 65+ metres, making it one of the deepest dive sites in Thailand.

Departing Koh Lanta just before 8:30 am, we usually arrive at the dive sites around 9:30 am. Depending on the currents, we usually like to dive Hin Muang first, as it's the deeper dive.

The long ridge of Hin Muang is covered in many thousands of purple soft corals and anemones feeding on plankton drifting past on the currents, giving the reef it's name Hin Muang, Purple Rock.

The very densely packed reef is also covered in a huge number of hard corals in excellent, healthy condition.

Giant trevallies, huge emperors, and titan triggerfish roam the reefs hunting and feeding on the millions of fish found around this huge rocky ridge. Observe the wonders of nature at work and the complex ecosystem, as countless species thrive in constant motion, hunting, feeding and darting in and out of the reef.

Those divers looking more carefully will find numerous species of marine life which are not commonly seen at the other dive sites around Koh Lanta. Lucky divers may also see manta rays and whale sharks out in the blue, or in the shallows above the reef playing in divers bubbles.

You can expect mild to medium currents at this dive site and must be comfortable making a mid-water ascent and safety stop with no physical reference in stronger currents.

We recommend the PADI Advanced Open Water Diver course for less experienced divers, providing an introduction to deeper dives in stronger currents.

Hin Daeng

The rock formation of Hin Daeng (Red Rock) breaks the surface and slopes gently down to a depth of over 50 metres on one side, with a steeper drop on the other side. The red-coloured rocks and walls are covered with red and purple soft corals, anemones and algae.

After diving around Hin Muang, we can tie up our speedboat by mooring up to the rocky outcropping of Hin Daeng, have a relaxing lunch, and plan the second dive.

This pinnacle features a sloping channel with near vertical sides running through the center of the reef, providing shelter from some of the stronger currents and home to many species of marine life that you won't normally see on the outer parts of this reef.

The rocks and corals are home to millions of small reef fish, boxer shrimps, octopus and giant morays. Schools of jack fish, barracudas, trevally, mackerel and rainbow runners circle around this reef to feed.

Between the months of November and March, Manta Rays are often found around here and you might even come eye-to-eye with the gentle giant, the Whale Shark, which is spotted several times a year at this site.

If you don't want to waste most of the day on a larger, slower dive boat, our speed boats are the perfect way to dive Hin Daeng & Hin Muang from Koh Lanta.
