Welcome to Turtle Rock
Start your dive at the buoy line in the middle of the bay. Directly West from the bottom of the line is where you can find a few big coral colonies with lots of life around them. It is good to spend at least half your dive in this area as there is usually more life here than on the rest of the site. If you take the time to explore, you will find a lot more.
The shallowest part of the coral structure is at around 16m. Slowly swim out along the coral to its deepest point at 20m. Here you can find several spearing mantis shrimp, in their holes in the sand, just underneath the coral. If you swim slowly, and look everywhere, you can find small and rare creatures including the oscillated dwarf lionfish.
Follow the coral back up to around 16m again. This area is usually quite lively when it is dark and you can look for Moray eels, lionfish and octopus all out hunting. If you want to see more action then just be careful where you point your torch. If you point it directly in the eyes of fish then it is blinding. Not only is this damaging to their eyes, it will also disrupt their normal behaviour.
Once you have finished looking around the coral garden then you can shallow up to the boulders in the bay. The edge of the boulders are between 12m-20m. There are various other species that you can find inside the boulder’s cracks, including lobsters, reef crabs and sometimes frogfish. It is also common to see Morays and octopus in the shallows as well.
As with most night dives, the key is not to swim too far from the boat. If you swim towards Turtle rock for the first half of the dive, and back along the reef for the second half, then you should be able to see the floodlights at the back of your boat. This makes it easy to navigate your way back to the boat at the end of the dive.
Do your safety stop near the back of the boat. You can either use a surface marker buoy or you can point your torch directly towards the surface to make you clearly visible below. Head back onto the boat for a hot shower, dinner and a delicious beverage. Spending the evening on a Similan Liveaboard, in the beautiful Donald duck bay, is everything you could expect from a Thailand diving holiday.
