Dive Koh Rok - Hin Ngam

Mu Ko Lanta National Park

Diving Koh Rok - Hin Ngam

Hin Ngam is located at the south west part of Koh Rok Noi and is a rocky dive site with an abundance of hard and soft corals.

The dive starts at the south west following the reef on the left shoulder. The shallows begin with large boulders, becoming smaller with depth, eventually revealing a gently sloping reef from around 7 - 8m down to 18m +. This is a great area for macro life such as shrimp and nudibranchs, and for larger species of sea cucumber, angelfish, surgeonfish, moray eels and turtles.

Diving @ Koh Rok with Dive & Relax

You will find hard corals, including boulder corals and branching corals, soft corals, including sea whips, anemones, clownfish and many other species in this area. If you are very lucky, you may spot a marble ray, guitar sharks, eagle rays or possibly the occasional whale shark in this area.

As you continue eastward you find larger rocks, boulders and hard coral bommies, surrounded by bubble corals, gorgonian sea fans and whip corals, giant barrel sponges, glassfish, fusiliers, groupers, surgeonfish and moray eels.

The reef slope becomes more steep, strewn with bubble corals and barrel sponges, gradually becoming a steep wall in deeper areas.

A huge underwater rocky finger marks the end of the first bay, and the start of the second bay as we turn the corner to the right. The imposing rock face creates a dramatic natural geological barrier which marks the end of the first sloping reef, and the start of the second sloping reef as we enter the next bay. Around the finger and in deeper areas, we can see larger fish, including the giant potato grouper.

After the huge rocky finger, we again find ourselves on a broad sloping reef, more rocky in the shallows. Again, hard and soft corals are found at all depths and we enter the shallows where we end the dive.

There is a great abundance of sea whip corals in the shallower areas. Batfish, angelfish, wrasse, parrotfish, sweetlips, surgeonfish, snapper and turtles can all be found here. The shallow area here is also great for snorkeling.
