This is a tiny islet with a lonely tree growing on the top.

Underwater, you will find a steep rocky reef with lots of tube and fan corals. Lots of critters hang around the cracks including nudibranchs, pipefish and seahorses.

Visibility and currents can sometimes be challenging but it is a rewarding site.

Strong currents bring with them teams of schooling fish and with superb visibility the atmosphere on the reef at  North Twin is breathtaking. Hard corals have seen damage from the rise in water temperature but soft corals  adorn the reef and bring vibrancy.

In South Twin we can expect to see an  abundance of moray eels, harlequin sweetlips and cuttlefish. 

Captain’s Rock, otherwise known as Bowie Rock, is a sloping reef with huge soft coral covered boulders. Sweetlips, barracuda, a variety of angel fish and many smaller creatures including devil scorpion fish, pipe fish, shrimps and flabellina nudibranchs can be found all over the reef. Mantas may also been seen here.

Black Rock stands alone in the Andaman Sea 100 miles northwest of the Thai Burmese border town of Kawthaung. The rock acts as a natural magnet for fish and other marine life. An excellent multi-level site, you can start your dive anywhere around the perimeter, depending on currents. 

Underwater terrain on the south side consists of a vertical wall down to roughly 27m, where it becomes a more  gradual slope. Just off the south-west corner is a particularly interesting area, where a detached rock formation  rises from very deep water to about 24m. These rocks are covered with small, vibrant soft corals, and often attract schooling snappers and rainbow runners.  

Back at the main islet, deeper sections are decorated with orange gorgonian fans, along with fields of corallimorpharians (they look like stony corals) on the sloping west and north sides. At the eastern tip, watch for vast numbers of magnificent anemones, especially at dawn and dusk when they show off their colourful bases. A wide range of invertebrate life can be found at Black Rock, including smashing and spearing mantis shrimp, spiny lobsters, hermit crabs, sea stars, cowrie shells, harlequin shrimp, octopus and cuttlefish. 

During safety stops, move slowly along the eastern and western ends of the south wall to find brilliantly coloured  elegant hermit crabs and a variety of nudibranchs, as well as golden wentletrap snails that feed on the orange  cup coral. Fish life is also abundant and varied, with a chance to see almost anything from scorpion fish and giant  morays to marbled sting rays. Mantas and even whale sharks are also sometimes visitors of this site.

As the name Fan Forest Pinnacle suggests, it is a submerged pinnacle famous for the amount of gorgonian sea fans. The biggest gorgonians are in deeper waters around 20 m and below.  

They are very healthy and support a large variety of marine life including feather stars, cowries, hawk fish and  shrimps. Schooling fish include snapper, trevally, rainbow runners and fusiliers. Moray eels and scorpion fish are  also numerous. A short trip south of Sea Fan, Western Rocky is the scene of dramatic underwater terrain on this excellent dive  site, which consists of a main islet plus several detached pinnacles. Among the more striking features of the  main islet is a huge underwater archway where schooling snapper often hang out. 

The soft limestone island is riddled with holes and crevices, providing hiding places for hinge-beak, saron and  harlequin shrimps, thorny oysters, cowrie shells, nudibranchs, spiny lobsters and moray eels.  

Large gorgonian fans and lush soft corals populate many of the deeper areas, while shallow portions of the south side wall are covered with orange cup corals and colourful encrusting sponges. Fish life can include almost anything from ornate ghost pipefish to frog fish to schooling batfish. Western Rocky pinnacle is shaped like a cheese wedge covered by both hard and soft corals, lots of trevally and tuna, and if you are lucky, the elusive bow mouth guitarfish.

All around this site, marine life is extremely rich and diverse. There are three different rocky islets with vertical walls as well as sloping reef. Many areas are populated with fields of anemones, which are home to five different species of anemone fish.

Elsewhere, large tubastrea coral trees sprout from the rocky terrain, accompanied by crinoids, gorgonian fans and pastel green rope sponge. Tiger tail seahorses are often encountered on the deep edges of the slope, as are many varieties of morays – often several species in the same hole.  

Cuttlefish may be found at nearly any depth, sometimes courting and mating. Ornate ghost pipefish, cowrie  shells, octopus, reef squid, jaw fish, porcelain crabs, long nose pipefish, and mantis shrimps are often seen at  this site. Scorpion fish are very abundant, so be careful where you place your hands! Between the three pinnacles  and surrounding bottom, Shark Cave easily lends itself to several dives to enjoy the diversity of the reef and to  marvel in the chasm of the Shark Cave! Nurse sharks can be found lurking inside the cavern along with marble  rays, ghost pipefish and plenty of other fascinating creatures, including blue ribbon eels.

Due to its remote location this is a good dive site for appreciating a kaleidoscope of colours from the  hundreds of corals types in abundance such as table corals, mosaic corals and red whip corals to name a few.

The  corals are surrounded by healthy reef life and huge submerged boulders, as well as the occasional sting ray and  the rare leopard sharks on the sea bed nearby. There is also a good chance of seeing black banded sea snakes  here. Chances of spotting sharks, whale sharks and mantas. The “Sea Fan Forest” is an enchanting patch where  lionfish, moorish idols and several cowries are present.

As its name suggests, this is a magical dive site with towering walls descending into the depths. Below the water  you will find a lunar site of boulders, made up from the taller reaches of Tower Rock in years past. 

The walls are laced with whip corals and sea fans, oysters and clams. White banded cleaner shrimp and ornate  spiny lobster hide amongst the crags, whilst blue faced angelfish and yellow striped fusiliers dance their way up  the walls. 

Larger visitors include manta rays and mobula rays, as well as blacktip and whitetip reef sharks. Moray eels,  bearded scorpionfish, schools of snappers and fusiliers are among the usual suspects.
