Diving in Southern Thailand

Hin Daeng and Hin Muang

South of Phuket and Koh Phi Phi, towards the border with Malaysia lie some more excellent dive sites.

Hin Daeng (Red Rock) and Hin Muang (Purple rock) are truly world class sites, offering steep walls, big fish and lush soft coral gardens. Whalesharks and manta rays are seen here quite regularly.

Koh Ha

Koh Ha on the level of Koh Lanta and exists out of 5 small islands (Ha is Thai for five). Here we can find several dive possibilities and it's also a great spot for a night diving. The highlight dive at Koh Ha is at a fantastic cavern, also known as 'Koh Ha Cathedral'.

Let's go diving!

Hin Daeng


Hin Daeng

Hin Daeng protrudes about 3 meters above the water, but below, it drops straight down to 60+ meters on the southern side. The dive site got it's name from the beautiful red corals that populate most of the dive site.

The south western side drops to over 60 meters, creating a steep wall of soft corals. Leopard sharks are often seen in this area.

The eastern side has the best soft coral growth and two ridges that slope gently into deeper water. Jacks hang out often close to the rock.

In shallower areas moray eels are commonly found hiding in cracks in the rock face. Hin Daeng is also good for critters such as nudibranchs, cowrie shells and various species of shrimps.

During the end of the season, we usually have a good chance to see here whale sharks or manta rays.

Hin Muang


Hin Muang

Hin Muang or ‘Purple Rock’ is completely submerged and derives it's name from the vast number of purple corals covering the pinnacle.

The reef is 200 meters long and less than 20 meters wide, and comprises three main pinnacles and several smaller ones.

Many giant morays can be seen amongst the cracks and crevices and large leopard sharks are often found lying on the sand in the 40-meter ridges.

It is fascinating to watch the huge schools of yellow snappers and fusiliers schooling around the tops of the pinnacles, while rainbow runners, jacks and travalies dart in, hoping for a quick snack. The sheer volume of fish life is an amazing spectacle to witness.

At this spot regularly manta rays and whale sharks come to feed and to be cleaned.

Koh Ha


Koh Ha

A circle of 5 small limestone islands, Koh Ha has numerous dive sites which all enjoy spectacular visibility and some great marine life.

Wall dives outside the rocks yield huge schools of barracudas hanging in the blue, octopus moving along the coral and seahorses at 35 metres, waiting in the archway of a dramatic swim through.

Koh Ha Yai has a beautiful chimney ascent, where you can slowly come up within the very rock itselves and reach the air pocket at the top of the cave.

Within the shallow lagoon formed by the 5 islands, there are numerous macro delights, including the harlequin shrimp and ghost pipe fishes.

Koh Ha Cathedral


Koh Ha Cathedral

There is excellent opportunity for adventure here.

The south western face of the island has a cave with two large entrances. The western of these has a hole in the rock at a depth of 5 meters. This immediately enters the larger of two connected cathedrals, which rise an impressive 30m above sea-level.

The other entrance/exit, at the eastern end, is deeper, at 16 meters. It is not dark in the cathedrals; light enters from the huge openings. Directly in front of the cave are a number of large rocks highlighted by sea fans and soft corals.

There are also plenty of sea whips, which are worth closer inspection as it will reveal a variety of tiny camouflaged invertebrates.
