Thailand Aggressor - itineraries

Similan - Bon - Richeliu + Surin - Richeliu - Similan

Anita’s Reef - Barracuda’s Point, “Hin Muan Deaw”

The Thai name for this spectacular rock is “Hin Muan Deaw” and is the best way to describe how beautiful this rock really is, as it directly translates to “Whole roll (of film) rock”, as one can use an entire roll film solely on this rock. The reef slope falls from the reef flat at 15 – 35 ft (5 – 10 m) to the sand bottom at a maximum of 85 – 90 ft (26 - 28 m). Shallow coral gardens comprise huge pore and staghorn corals with small pinnacles. A big outcrop located on the southeast makes this dive site unique and attracts many photographers. Colorful soft corals, gigantic sea fans, and many species of hard corals surround this fantastic rock.

West of Eden

West of Eden basically comprises giant granite boulders that create nice canyons, with walls covered with colorful soft corals and giant sea fans. Some areas are characterized by rubble and sand slope falling to a depth of 100 – 115ft (30 - 35 m). The shallows are home to many reef fishes, and have stacked granite boulders covered with hard corals, soft corals, gorgonians and feather stars. This area is a nice place to look for macro subjects like nudibranchs and frogfish. Keep an eye out for cleaner pipefish and many banded pipefish in small crevices, as well as long-nose hawkfish perched in black coral bushes. The rubble and sand slope are good place to search for ribbon eels, dragonets and red fire gobies. Back at the reef, moray eels are quite common, as well as turtles and schools of angelfish. Occasionally, whitetip reef sharks cruise by.

Bon - Koh Bon West Ridge, Koh Talu

The wall, part of the Similan National Park, is decorated with various colorful soft corals and hard corals. From the ridge to the northeastern side are reefs that stretch along island. The reef slopes from a depth of 30 ft (10 m) down to a sandy bottom at 80 – 100 ft (25 - 30 m). The majority of corals here are hard corals, including staghorn coral and brain coral that are interspersed with a few big coral heads. To the northwest of the island, there is a submerged pinnacle. The pinnacle is at a depth of 60 – 150 ft (18 - 45 m) and is covered by an abundance of yellow soft corals and large sea fans. This site is a cleaning station for manta rays, so there is a high chance of finding at least one during a dive, particularly at the western ridge and northeastern outer reef. Koh Bon also has many kinds of sharks, such as leopard sharks and whitetip and blacktip reef sharks. Sometimes grey reef sharks swim by, and nurse sharks can be seen lying under coral heads. Schools of yellowtail barracuda, fusiliers, trevally, sweetlips and black and white snappers are all common in the area, as well as octopuses, sea snakes, and nudibranchs.

Tachi Reef – Leopard Shark Reef

Tachai Reef stretches through the eastern side of the island, going from the northeast to the southwest. The reef slope falls from 16 – 33 ft (5 - 10 m) to the sand floor at 82 – 98 ft (25 - 30 m). Hard corals cover the entire area, most of which are staghorn corals, pore corals, brain corals, and fire corals. In the southern part, the gentle slope becomes a steep drop-off that continues from the island down to 98 ft (30 m). Divers regularly see leopard sharks lying at the outer sandy area and sometimes in shallow areas. Large stingrays are found on occasion too. General reef fish include pufferfish, lionfish, parrotfish, and moray eels. At night, several species of crabs and shrimp come out to hunt. It is possible to see twin-spotted lionfish, a rare species of lionfish that tends to be shy and hide in crevices. Cuttlefish, nudibranchs and flatworm are also common.

Richelieu Rock – Hin Plo Naam

One of the most famous dive sites of Thailand, Richelieu Rock is an isolated pinnacle to the east of Surin Islands. Forming a horseshoe figure, the pinnacle fall steeply to the surrounding sand bottom at a maximum depth of 115 ft (35 m). The south side is a bay with a slope that gently falls to the deep, while the rest comprises sheer walls, groups of rock and numerous small caves that are home to various marine life. The majority of corals are colorful soft corals jostling against the wall, accompanied by huge sea fans, hard corals and sea anemones.
Due to the diversity of small and large creatures, Richelieu Rock is a paradise for underwater photographers. Ghost pipefish, frogfish, harlequin shrimp, seahorses, Janss pipefish are some of the smaller marine life that can be spotted here. Also, divers have often encountered cuttlefish mating. In addition, plenty of anemone fish species, particularly tomato clownfish, are regularly sighted. Different types of moray eels such as giant moray, zebra moray, and white-eyed moray are common. Pelagic fish swarming around the small outcrops include chevron barracuda, rainbow runners, and giant groupers resting on the sand floor are a common sight. Lastly, this site is famous in Thailand for being a hotspot for encounters with both whale sharks and manta rays.

Tachi Pinnacle – Twin Peaks

A solitary island located 20 km. north of Koh Bon, Koh Tachai has magnificent white sandy beaches with two interesting dive spots, southern pinnacles and eastern reef. Tachai Pinnacle or Twin Peaks are a pair of submerged pinnacles located 500 m south of Koh Tachai. The southern pinnacle is bigger, at a depth of 40 ft (12 m) from the top. It is a dome shape surrounded by large boulders. The sand bottom is at a depth of around 100 – 150 ft (30 - 45 m). To the west you will find large boulders, some of which have formed swim throughs. In the east, you will find stacks of small rock, most of which are cover by hard corals and sea whips. Colorful soft corals and sea fans dominate the northern area. The top of the pinnacle is a wide flat plain with bush and mountain coral. This huge pinnacle links to the small one with a sand patch at 80 ft (24 m). The smaller pinnacle comprises of a wide range of rock clusters and is home to large sea fans and corals, which are similar to the ones found in the southern pinnacle.
Manta rays visit this area for feeding and circling around the pinnacles. Some divers have encountered whale sharks as well. On the outer sand bed, divers can usually see leopard sharks, sometime three to four of them in the same dive. In addition, it is possible to find Jenkin’s rays, as well as whitetip sharks and blacktip reef sharks here as well. Swarm of chevron barracuda, bluefin trevally, batfish, snappers, and fusiliers are common here.

Elephant Head Rock - Hin Pusa, Hin Hua-ka-loak

Visible from the surface, Elephant Head Rock is the biggest pinnacle in the Similans. It is located 1.5 km south of Koh Similan. There are three large boulders that emerge above water. At this site, submerged boulders are piled up, forming sheer walls and swim-throughs that are covered with assorted colors of soft corals and sea fans. The site is surrounded by sand at a maximum depth of 115 – 130 ft (35 to 40 m).
One of the outstanding features of this site is the swim-throughs. In addition, cave walls are full of soft corals, creating plenty of magnificent scenery that makes you feel like you are swimming in an underwater valley. To the west of the giant rock is a sheer wall that falls to a depth of 130 ft (40 m). Divers have often seen whitetip and blacktip reef sharks outside the boulders. In addition, juvenile whitetip reef sharks can sometime be seen laying in the cracks of the boulders. In mid-water, schools of fish, including bluefin trevally, fusiliers and rainbow runners are common. Near the exposed boulders, giant trevally and great barracuda are a common sight. Also, divers may encounter large snappers and sweetlips in cracks, holes and swim-throughs.

Christmas Point

A cluster of submerged boulders, with the exception of a pinnacle at the surface that is located on the northwest ridge of Koh Ba-Ngu. Underwater, there are number of large stacked boulders that stretch from the island to a depth of 115 – 130 ft (35 - 40 m), which create an arch like swim-throughs at 80 ft (24 m). Colorful soft corals and sea fans cover the crevices. A hard coral garden made up of rows of staghorn and pore coral is located at a shallow depth of 30 ft (10 m).
Around the borders of the rocks and beyond, at a depth of 80 – 130 ft (25 - 40 m), you are likely to find leopard sharks, whitetip and blacktip reef sharks and other big fish such as Napoleon wrasse, great barracuda, giant trevally and tunas. At the swim-throughs, giant sweetlips and groupers can be seen hiding in crevices. School of fish including bluefin trevally, neon fusiliers, goatfish, and long nosed emperors are frequent visitors. Many small fish, such as purple fire gobies and red fire gobies are a familiar sight here. Ribbon eels, a rare species that camouflages on the sand like whip corals, can also be seen. Also, pipefish, nudibranchs, and porcelain crabs cab be found. It is possible to spot manta rays passing by as well.

Shark Fin Reef - Hin Phae, San cha-larm

A formation of granite boulders and hard corals to the southeast of Koh Pa-Yan. The site itself is approximately 1 km. long and lies from the northwest to the southeast. Normally three pinnacles can be seen from the surface, which gives the reef its name Shark Fin Reef. Boulders that fall steeply to 115 – 130 ft (35-40 m) and are surrounded by sand occupy the vast majority of the site. Due to the fact that the boulder formation is long, coral reefs have been divided into northern and southern areas. Both areas are steep and cliff-like. The northern area has more corals consisting mostly of staghorn coral and soft corals, combined with tiny rocks and sea fans. The southern side is made up primarily of sheer walls. Overall, at various parts of the reef, some pinnacles have stacked themselves on top of one another, forming many swim-throughs that divers can enjoy.
Near the sandy areas, you likely to find leopard sharks, whitetip and blacktip reef sharks, Kuhl’s stingrays and spotted garden eels. Furthermore, this site is one of the few areas in the Similans where you can see Napoleon wrasse and hump head parrotfish. Bigger than usual adult cube boxfish are often seen, particularly in the shallow waters of the east. Among the boulders, a lot of camouflaged marine life can be seen, including octopuses and devil scorpionfish. Manta rays can be spotted during the month of April and whale sharks have been report in the vicinity as well.

Declared a National Park in 1982, the Similans are comprised of 9 islands, which run roughly North to South with numerous smaller rock outcroppings.
With snow-white beaches, lush tropical jungle and spectacular dive sites in stunning turquoise waters, it’s not surprising that the Similans are ranked as one of the top 10 dive sites in the world!

Nearly all of the 9 islands are surrounded by huge underwater rock formations, eroded by the action of a relentless sea.
These stone giants are home to an amazing variety of marine life, with depths often reaching 40 meters or more. Narrow swim-thru’s, caverns and underwater canyons form a truly unique diving landscape.
With names like ‘Elephant Head’, ‘Boulder City’, ‘Sharkfin Reef’ and ‘East of Eden’, you’ll soon appreciate why the Similans deserve the reputation they’ve obtained.

Thailand Aggressor - diving

Similan islands dive sites

Thailand liveaboard trips to the Similan islands and Richelieu rock generally last 4-6 days and leave either from Phuket island on the west coast of Thailand or Thaplamu one and half hours north of Phuket.
Travelling overnight they arrive in the Similan islands on the following morning to begin your first days diving. Continuing north over the course of the trip to Koh Bon, Koh Tachai and finally the amazing Richelieu rock. These liveaboards encompass the best diving that Thailand has to offer on the best boats Thailand has to offer.?
All our boats are liveaboards for people enthusiastic or serious about their diving but also welcome snorkellers and non-divers who will have their own separate itinerary.

Boulder City (Island Three - Koh Payan)

Boulder City lies some 200 meter south of Koh Payan. The dive site is completely submerged with two mooring buoys to mark the location, one at the north end and one at the south. Descending down the north line takes you to 20 meters and the south line to 30 meters. This is a dive in the 20 to 30 meter mark making it not a long dive but the underwater scenery here is spectacular with large granite boulders some bigger than a house, with swim-throughs and the chance of swimming with large pelagics. Eagle and manta rays cruise around the large boulders while large fan tail rays rest in the sandy bottom. This is also where I have been lucky enough on two separate occasions last season to witness the mating of leopard sharks. With a family of large humphead parrot fish and napoleon wrasse living in the area the beautiful soft corals and large gorgonian sea fans make this an eye opening dive site with the occasional whale shark cruising past.

Koh Miang # 4 Honeymoon Bay

Honeymoon Bay is a beautiful bay on the back side of island 4 with its quiet beach and tranquil bay it’s the perfect place for a snorkel or our sunset dives on the gentle slopping reef down to 24 meters. In the shallows around the coral heads you will find octopus, crabs and mantis shrimps on the hunt for food.

With the occasional hawksbill sea turtle and white tip reef shark patrolling the reef will keep you busy on your dive.

Koh Payu # 7 Deep Six

Deep six lies on the northern tip of island 7 and has a buoy line running down to 18 meters there as the name implies you can descend down to over 60 meters. Here the dramatic underwater boulders have formed some excellent swim throughs, tunnels and canyons that make this an exciting dive. But down in the soft coral garden the largest gorgonian sea fans in the Similans survive untouched. With the occasional manta ray gliding passed in the blue will make for an enjoyable dive.

Elephant Head, Hin Pousar

Deep six lies on the northern tip of island 7 and has a buoy line running down to 18 meters there as the name implies you can descend down to over 60 meters. Here the dramatic underwater boulders have formed some excellent swim throughs, tunnels and canyons that make this an exciting dive. But down in the soft coral garden the largest gorgonian sea fans in the Similans survive untouched. With the occasional manta ray gliding passed in the blue will make for an enjoyable dive.

Koh Bangu #9 North Point

North point lies on the west side of the island with a dramatic underwater scenery of large boulders with canyons and swim throughs. As you descend down the line passed the tall fin bat fish and head through the tunnels, keep your eyes open for a pair of Napoleon wrasse. In between the large canyons grow large gorgonian sea fans with excellent soft corals hiding harlequin ghost pipe fish but a look out into the blue can be rewarding with frequent visits from the graceful manta ray passing over head.

Koh Bon - The Pinnacle

Koh Bon island lies 12 nautical miles south of Koh Tachai island and the dive site is located around 150 meters north west of the island and has no bouy line so location is by GPS. When the captain signals its time to jump into the blue and descend down to the pinnacles. The top is around 18 meters and continues to run down to over 50 meters to the sand bottom were the docile leopard shark sleeps while white tip reef sharks patrol the reef in search of a meal.

These amazing pinnacles are covered with colourful soft coral trees, large gorgonian sea fans and barrel sponges running down the walls. With 5 species of clown fish in the magnificent anemones and their shrimp and porcelain crab hosts its difficult to keep your eyes of the pinnacles but a look out in to the blue can be rewarding with manta rays gliding around and the occasional whale shark. But don’t forget to keep a check on your air supply as its time to head back to the surface and leave these beautiful creatures behind.

Koh Tachai Island - The Dome

Koh Tachai lies 22 nautical miles south of Surin, the dive site is located around 200 meters south of the island and is marked with a bouy line which descends down to 16 meters to reach the top of the plateau. From here you decide which way to go ? North or South. North takes you over the plateau to the beautiful coral garden at around 22meters to 26meters with some of the best soft corals and sea fans in the area, which will keep underwater photographers busy. South takes you down over the large boulders to between 36meters and 40meters to reach the sandy bottom looking for the docile leopard shark and large stingrays. Up above schooling great barracudas with tunas and trevallys darting down to catch the baitfish hanging around the reef. With a multitude of small creatures to look at try not to forget a look into the blue to see the manta rays gliding past and the occasional whale shark make Koh Tachai a spectacular dive site.

Richelieu Rock

Richelieu lies 7.5 nautical miles east of the Surin islands national marine park. Here this large rock pinnacle just breaks the surface at low tide and descends down to around 33 meters to the sandy bottom. The northern side has an excellent wall with lots of cracks and holes for you to look inside. The wall is covered with coral and zig zag oysters where you can find over ten species of moray eels like the commonly spotted white eyed, giant, yellow edged, and bartail morays or the shy dragon, leopard, honeycomb and zebra morays.

The wall is all so home to many species of shrimps from the cleaners, anemone, saron, squat and the colorful harlequin shrimps. The west side contains mostly soft corals and sea fans with ghost pipefish and tigertail sea horses hiding in between the branches. But its here where we all so encounter large schools of silver jacks and bluefin trevallys with chevron and great barracudas too.

Its also home to the gentle giant the whale shark anywhere from 2 meter babys to 8 meter subadults. The walls seem to move with so much life or look closely at the camouflaged scorpion, stone and lionfishes that blend in to the rock. A truly spectacular dive site no matter what the visibility.

Koh Bida Nok and Koh Bida Nai Islands - Koh Phi Phi

These two uninhabited islands lie south of Phi Phi and are a Mecca for leopard sharks. These harmless and docile creatures are usually sleeping around the sand and coral banks of the islands usually no deeper than 20 meters. With Bida Nok as the larger of the two it offers great hard and soft corals with turtles and sea snakes passing bye. The deeper of the two with depths to 30 meters on the west side wall teeming with life from lionfish to baby morays poking there heads from the cracks and well camouflaged octopuses blending in to the rocks will keep your eyes busy on this dive site.

Bida Nai island smaller and slightly shallower offers the chance to see the sleeping leopard shark anywhere from 1 to 10 sharks resting on the bottom in between the staghorn corals. Here the soft corals are abound with their beautiful colors but look closely at the sea fans to find the Tiger-tail sea horse. With two swim-throughs covered in small baitfish and shrimps, lots of colorful reef fish and schools of barracuda and trevallys darting over the reef, and not forgetting the many nudibranches along the way make this a wonderful dive site.
