Ao Nang Local Islands:
Depth: 9-16 meters (30 – 50 feet)
Directly opposite to Koh Gai (Chicken island) this is a great all around dive site, great for beginners but also with a good number of small nudibranchs, seahorses and other small invertebrates so it makes for a great dive site for advanced divers as well.
Koh Kom is essentially a large beaches island rock protruding from the sandy bottom, with a. Few smaller rocky outcroppings around the main island.
There is a large cave at Koh Kom featuring three separate entrances, two of the entrances are large enough for divers to swim inside, the third is a little on the small side so caution should be used when entering.
Surrounding the main island is a sandy bottom with a few various rocky outcroppings, in the sandy area, blue spotted stingrays, bent stick pipefish as well as leopard sharks are regularly seen.
Due to the swim through and a narrow entrance, dining tidal shirts this dive site can get a little rough when the tide is moving, so we recommend to dive at Koh Kom only during slack tide.
Depth: 9-18 meters (30 – 55 feet)
Koh Yawasam is two separate islands separated by a shallow passage making it a great dive site for snorkeling as well as SCUBA diving. It’s popular stop on the #1 Ao Nang based tour, the 4 island trip.
Koh Yawasam is similar to Koh Kom in that it is a air of large rocks, rather cylindrical in shape surrounded of a sandy bottom and a few rocky o
utcroppings fringing the islands. Located about 15-20 minutes from Ao Nang Koh Yawasam is one of the all time favorites for local diving days.
A few rocky outcroppings pinnacle like in shape just a few meters from the main islands of Koh Yawasam are home to a number of Bigeye Snappers and silver travellies. On the Northern edge of the pinnacles are a few staghorn corals in which seahorses and pygmy seahorses can often be found.
In the sandy area surrounding the main islands blue spotted stingrays can often be found.
If you are diving during tidal shift this site makes for a good drift dive, leading divers from one island to the other at a comfortable pace.
Koh Mae Urai:
Depth: 9-16 meters (30 – 50 feet)
Directly opposite Koh Talu, Koh Mae Urai makes for a great local island dive site, especially is your diving during a tidal shift as there have been divers who have drift dived between both dive sites. Talk to your dive operator to see if this might be a possibility.
The whole of Koh Mae Urai is a group of pinnacles of similar height surrounding a main island similar to other local dive sites. The different at Koh Mae Urai is that the pinnacles can sometimes be easily lost if the guide doesn’t have experience at the dive site or the visibility is poor.
If the current isn’t too strong and the visibility this can actually be one of the most beautiful dive sites of the local islands of Ao Nang. There are numerous soft corals which have grown on the various pinnacles around the site.
On the Western side of the whole dive site is a nice, interesting wide swim through, perfect for everyone to try out and play around with. There are a number of large yellow seafnas that live here, take a look in these fans for seahorses, they is usually where they stay.
Depth: 9-16 meters (30 – 50 feet)
The swim through island as it’s often known as due to the large hole through the center of the island. The swim through itself is about 40 meters in length and wide enough for up to five divers to travel through shoulder to shoulder.
The island like the many other locals island of Ao Nang is a similar topography in that it is a large cylindrical like island surrounded by sandy shores. The sandy shores surrounded the main island are home to a host of blue spotted stingrays, ghost pipefish and long spiny urchins. There are a number of rocky outcroppings fringing the main island is Koh Talu and these are full of soft and hard corals worth inspecting. Inside these soft and har corals you can find many species of damselfish, butterfly fish, digging goby’s and many times a seahorse or two.
There is also a smaller swim through on the Northern side of the island, this is a great swimthrough as it’s smaller than the main islands swim through and offers a more intimate experience. At the smaller swim through, there is also a number of seahorses there as well as the occasional pufferfish that comes through time to time.
Only thing on Koh Talu is that during a strong tidal shift (current) the dive site can provide a number of dangers so be aware and talk with your guide first.
Depth: 9-16 meters (30 – 50 feet)
Literally translated from Thai to English as five island, Koh Has is a great easy local dive site which although not as diverse as other dive sites is home to a number of flowing and beautiful sea fans and soft corals which can make for beautiful photo and video opportunities.
One thing that stands out at Koh Has is your chance to see black tipped reef sharks! There are a number of schools that can easily be seen throughout the dive.
Black tipped reef sharks are like many other shark species harmless, there have been no known records of anyone being bitten by black tipped reef sharks in the region in recorded history. In fact black tipped reef sharks are often so timid of divers and the bubbles that SCUBA diving creates they will swim away if shared. So if you do happen to catch a glimpse of one or more sharks stay calm and maybe you can coax them to come a little closer for a better view.
Depth: 9-20 meters (30 – 60 feet)
By far the most popular dive site of the local islands, Koh Sii can be sometimes crowded so if you see a number of other dive boats present when you arrive, talk with your guide to see about an alternate dive site.
Again Koh Sii due to it’s proximity and quality of life found here is often a popular snorkeling site for many local companies offer day trips
Koh Sii is actually 3 separate islands running in the North to South orientation. On the Northern islands there is a swim through which can be accessed right from the boat, making for an interesting beginning to your dive.
There is a long wall along the North East side of Koh Sii on which there is a number of fan and stag horn corals which offer the best possibility to find tiger tail seahorses.
There are often schools of barracuda’s swimming around the various rocky outcroppings surrounding the main three islands. Barracudas although they have a bad reputation and have a certain ominous look to them are harmless and will not harm you. There is a chance that you can also see the large resident common grouper, who measures 1.5 meters in length and at least 250 kilograms. You can see the grouper slowly swimming throughout the dive site.
Koh Yung Pinnacle:
Depth: 12-20 meters (40 – 60 feet)
A rare site for many dive operators to visit but some will venture for a dive on the right day, get in touch with your dive operators to ask them if they have trips to Koh Yung.
Koh Yung is not a good dive for inexperienced divers as the site is print to extremely strong currents that can come through the area and if not prepared cause panic in inexperienced divers. Slack tide is the best time of day to visit Koh Yung, but your dive provider will ahve more detailed information on the perfect dive conditions.
The more shallow actions of the pinnacle are covered in a variety of colored soft corals and anemones with damsel and clown fish darting throughout the tentacles of the anemones.
As you get to the deeper waters of the dive 20-30 meters, there are a lot of large sea fans with butterfly fish and trigger fish darting around the area.
There are also a large number of yellow eyed moray eels poking out from the various crevices in the rock. Keep you eyes out for them as they will often have a number of cleaner shrimp working on their teeth while you pass by.
Koh Phi Phi:
Koh Phi Phi, being 2 separate islands Koh Phi Phi Don and Koh Phi Phi Lae are home to a great number of high quality dive sites despite the fact thats it’s the busiest and most dived area in the region. Such popular sites as Ao Nui, Viking cave, Phi Lae wall and Losama bay. All of these dive sites are more primarily designed for open water and advanced open water divers as the depths can often drop below 18 meters. These dive sites are all around the islands and although are often dived by a variety of operators can be busy. That being said these dive sites are all very large and there can be up to 50-100 divers at a single dive site without clogging the dive site at all, so don’t worry.
The dive sites throughout Koh Phi Phi are arguably the best generally speaking dive sites in the region so if you have only 1 day budgeted of diving and are thinking of where to dive, Pick one of the sites around Koh Phi Phi and you’ll be happy.
Depth: 14-24 meters (38 – 70 feet)
A small bay area on the Northwest Koh Phi Don, Ao Nui is a graet site to dive as the bay area is sheltered by a large oval shaped rock keeping the bay safe secluded. The bay area is also home to a quiet beach often visited by kayakers coming from Ton Sai Bay.
The dive site relatively shallow, with some points outside the protecting rocks dipping down to 20 meters, generally speaking the whole dive site is around 12-16 meters.
The protecting rocks provide for a great centerpiece for divers to use as starting point for their dive. By jumping in on the protected side and working your way around the rock clockwise until you’ve gone around the whole rock, taking short trips out to various pinnacles.
All along the Northern side of the protecting rock is a range of soft corals and rare nudibranchs which can be found only after close inspection.
Tigertail seahorses are commonly found here along with various lion fish. There are often yellow boxfish found in small nooks and crannies around Ao Nui, so keep your eyes open for these little beauties.
The Southern Tip:
Depth: 16-26 meters (45 – 75 feet)
A more advanced dive as the currents can toss any diver in all directions when the tide is flowing. That and the fact that the dive site is rarely dived today due to long tail boat traffic in the region.
The dive site is located as you could guess, off the Southern tip of Koh Phi Phi Don, featuring a number of canyons, channels and swimthoughs worth anyones time to explore and visit.
There are often octopuses found here but they are rather hard to spot so go slow and keep your eyes open.
Lastly whats worth noting on this dive site is that there is an extensive cave system with an entrance at The Southern Tip, making it a great jump off point for those cave divers who are looking for a good tech dive.
Depth: 7-19 meters (30 – 60 feet)
There are a number of black tipped reef sharks that dot the perimeter of Maya Nui so keep your eyes open you might get lucky and spot a few of them.
Maya Nui is located just north of the ever popular Maya Bay so there is a good deal of boat traffic present here, yet the dive site is spread out over a long distance so there is always plenty of space for everyone. Overall Maya Nui is a shallow dive site with depths ranging from 7M – 20M, making it. Bright and exciting dive for those of all levels. The resident black tipped reef sharks can be seen from any depth, so keep your eyes on the lookout always.
The Maya Nui area extends to cover a little cove with depths not more than 12 meters, and then extends out towards the entrance to Maya Bay. On the Southern side of the dive site there are a number of large boulders which for great hiding places for numerous fish and invertebrate species. You can often spot large groupers and or parrotfish. There are also. Number of yellow eyed moray eels which live in and around the boulders.
Depth: 8-24 meters (25 – 7 feet)
Maya Corner is the area in-between Maya Bay entrance and Maya Nui dive sites, it does wrap around the edge of the wall separating the two areas. Often dives will start in Maya corner and end in Maya Nui, or start in Maya Nui and end at Maya Corner.5
Maya Corner is home to two beautiful swim throughs although they can be crowded with fish, soft corals and possibly other divers there can only be one diver inside at a time so you might have to wait when you show up to enter the swim through.
The corner itself starts next to the island that is Koh Phi Phi Lae at a depth of about 10 meters and drops off to around 25 meters as you get further from the islands wall.
Around the corner you have a good chance to see a hawksbill or green sea turtle passing by or possibly stopping to munch of some of the soft corals in the area.
One thing to keep in mind at Maya Cornet and Maya Nui for that matter is the presence of stonefish. Stone fish are a unique fish with a large spine on their back capable of delivering large amount of poison into divers who unfortunately step on them. The issue with stonefish is that they have a great camouflage and can often be very difficult to see and therefore avoid. As a good rule of thumb you should not touch anything on the seafloor or on rocks which you cannot identify.
There are numerous other species of shrimp and fish found here, therefore if there is the option to dive this unique and fascinating dive site it should not go overlooked. There have also been sightings of whale sharks passing by this area. They never get that close to the common dive sites so keep your eyes open on the horizon when there’s good visibility.
Depth: 9-20 meters (30 – 60 feet)
The ever famous Maya Bay, home to The Beach, the backdrop for the Leonard DiCaprio blockbuster hit. Maya Bay is closed 4 months a year, every June – September to give corals and fish the chance to regrow. During the periods that t’s open though, this is a peaceful and relaxing dive site.
Often divers choose to take Maya Bay as a one way dive, either starting inside the bay and getting picked up at Maya Corner, or by starting at Maya Corner and ending at Maya Bay.
There are numerous swim thoughs all along the entranceway into Maya Bay, they range in size and shape but all are worth it if you’re feeling the urge.
Due to the fact that the dive site is protected by Maya Bay itself, there is little change from shifts in current here. That being said drift diving is not really an option at Maya Bay.
Depth: 12-18 meters (40 – 55 feet)
On the backside of Maya Bay on Koh Phi Phi Lae, Losamah bay is similar dive site to the earlier mentioned Ao Nui. It’s a bay area with a central rock providing a great place to swim around and observe the various corals and fish that live there.
The whole bay area is reatively shallow in depth with most areas measuring only 10-18 meters so this is a great side for open water divers.
The central rock is a great growing area for soft corals so make sure you ask about circulating around the rock to catch a glimpse of this beauty.
If you scoot around to the Eastern edge of the bay there is a good chance you can catch a glimpse of the resident large common grouper that lives there. Be aware it’s not dangerous in the least bit, but big so you might get a little shocked if you see it.
Phi Lae Wall:
Depth: 12-24 meters (40 – 75 feet)
A long wall just in-between viking cave and Phi Lae lagoon on Koh Phi Phi Lae, schools of sergeant major damsel fish as well as hawksbill sea turtles are common sights here. It is one of the preferred drift dive sites in the region, so ask your guide if it might be possible to drift dive here.
The site is also a popular stop for a number of snorkeling trips which leave form Koh Phi Phi daily so prepare for groups to be in the area.
In Terms of marine life in the area there are often schools of barracuda found along the Phi Lae Wall, so keep your eyes open for one of these such schools as they are beautiful and make for great photos and videos.
Depth: 9-25 meters (30 – 75 feet)
Popular for the large schools of longfin batfish that live here. They moved into the dive site when artificial concrete structures were placed on the site to provide growth space for corals and reef expansion. The long fin batfish moved in and never left since 2007.
Since these longfin batfish have been living in the same area for so long and have had so many divers approach them they are typically very comfortable with divers and very photogenic. So if you’re looking for a good place to grab photos and videos of large schools of fish, this is the dive site you don’t want to miss.
Depth: 8-17 meters (25 – 48 feet)
The site where concrete blocks were set up as artificial reef items for schooling marine life in the region there is always unique fish and beautiful images to catch at viking bay.
Located just at the end of Phi Lae Wall and next to Viking cave Viking bay is a convenient dive site if you’re looking for a day of diving without too much moving needed in between dive sites.
There is a resident population of long fin batfish that moved into the area some 10 years ago and haven’t left, so get your camera ready to catch some images of these stunning schools of 500+ fish.
The shallower bay area and concrete artificial reef structures is about 20-30 meters so you can easily visit the artificial reefs as well as the bay area on a single tank of air.
In addition to the large schools of long fin batfish found in the area, you can also spot a good number of soft corals, lionfish, parrotfish and pufferfish swimming through the the artificial reef.
Depth: 9-20 meters (30 – 60 feet)
Not a popular dive site for many operators nowadays but this even more the reason to ask your operator if this is site which diving is possible.
Hin Klai is a unique dive site featuring some of the biggest and vast stag horn coral gardens the region has to offer.
There is almost always a number of resident lion fish circling around the dive site, keep your eyes open and cameras going, but don’t touch the lion fish is a poisonous.
There are often a number of leopard sharks found here, along with ghost pipefish and large seafans providing protection to the smaller fish on the reef.
Depth: 10-20 meters (35 – 65 feet)
About 500 meters off of the Southern end of Koh Phi Phi Lae is a pair of dive sites Bida Nok and Bida Nai. They are in some regards the best dive sites Koh Phi Phi has to offer as the visibility there is usually 20+ meters as well there is usually at least 2 or more leopard sharks basking somewhere on the bottom (in addition to the numerous other marina life present).
Both islands are similar in design an average depth of 14-20 meters, maxing out at 30 meters.There is a range of pinnacles to swim around and explore.
There is a dive site further from Bida Nok and Bida Yai called His Bida, something like a half submerged hand reaching outwards to the surface in a large central pinnacle.
Bida Nai off to the Eastern side of the dive site lies a small field of anemones that are fringed by a similar large field of stag horn corals. There are a number of pinnacles off from the Amin island worth exploring so talk with your guide to see about planning the dive to incorporate visiting some of them.
Bida Nok features a large central island surrounded by a sandy bottom as well as a number of pinnacles that extend below the surface off the Southern side of the island. Off the Western side of Bida Nok there is a small cave worth visiting as there is usually frogfish, pipefish, fan corals and anemones covering the cave walls.
To the South of the island is a sloping pinnacle like reef that drops to 30 meters and is is a great resting place for black tired reef sharks, hawksbill sea turtles and leopard sharks.
Depth: 10-20 meters (35 – 65 feet)
A small pinnacle like reef about 1 kilometer South of Bik Nok and Bida Noi, Hin Bida rises from a depth about abut 25 meters to just below the surface. The pinnacle is not unlike a pyramid with a variety of different things to visit and see depending on the side of the pinnacle you dive.
There are often a number of leopard sharks resting around the sandy base of the reef, so keep your eyes out. Also noteworthy to mention that the is a rather aggressive black triggerfish who lives here, be careful he bites and will attack when you get close. Although beautiful to see and take photos of a visit with the triggerfish should not be taken lightly, their teeth are big. There is a long range of stag horn corals which extend off the Northeast edge of the pinnacle, there is plenty of pipefish, damselfish and nudibranchs worth looking for here.
Depth: 8-16 meters (25 – 45 feet)
The smaller of Hin Daeng, Hin Muang gets it’s name rather obviously after the multitude of purple anemones which cover the reef at it’s more shallower depths. Muang in Thai means purple. Hin Meuang is famous for the manta ray cleaning station which can be spotted (if there are manta’s visiting) at around 10 meters deep. Talk to the dive master or dive instructor prior to going on the dive if you can just hover and observe these gentle giants as they are cleaned. Not all but some dive guides will be alright with a shallow, easy going dive, so just ask. Hin Meuang is a deep dive site which can often be blasted by ocean currents so this is not a good beginner dive site, we typically recommend diving Hin Meuang for Advanced-Open water Divers with at least 30 dives on their log.
Depth: 20-70 meters (65 – 230 feet)
Arguably the holy grail of dive sites in Krabi province, Hin Daeng offers plenty to experienced divers. With a depth of around 70 meters and frequent tidal currents this is not a great dive site choice for beginner divers. It’s name comes from the red rocks which surround the pinnacle and make up the reef section, Daeng in Thai means ‘Red’. As we said above this is ‘holy-grail’ of the dive sites of Krabi at Hin Daeng, you have a near constant flow of whale sharks and manta rays which browse the waters surrounding the dive site. There is also a good chance that you can see a grey reef shark, also in the shallower waters around Hin Daeng there is a large school of long fin batfish which make for some great photos if you’ve got the gear for underwater photos.
Koh Haa Yai Lagoon:
Depth: 14-28 meters (35 – 80 feet)
A perfect dive for any diver, regardless of their ability. Koh Has Lagoon is one of the ideal diving locations as it has so much to offer divers of all abilities and experience levels. The dive site is one of the preferred dive sites for open water courses as there is plenty of sandy patches which are great to practice skills at. There are a number of corals which surround the central sandy patches, each of the coral outcroppings are rich with anemones, brain corals and stag horn corals as well as giant seaman corals. All great hiding places for small fish and nudibranches, moray eels, barracuda, travilies, giant parrotfish. Most accessible from Koh Lanta dive operators Koh Has Lagoon is well worth the trip if your staying on Koh Lanta.
Koh Haa Neua:
Depth: 12-18 meters (35 – 60 feet)
Famous for it’s beautiful narrow chimney which stretches form 20 meters to 5 meters and provides a great. The corals surrounding the edge of Koh Has Neua is rich with stag horn corals and seaman corals. Living in the corals there are a number of harlequin shrimp, short pipefish as well as yellow tailed seahorses. There are a number of frogfish that live at Koh Haa Neua so caution should be taken when you’re close to the rocks and corals.
Koh Haa Yai Cathedral:
Depth: 13-20 meters (35 – 65 feet)
Just a short distance to Koh Haa Lagoon, the Koh Haa Cathedral is famous for it’s massive cave, diving the dive site the apt name ‘cathedral’. The entrance to the cathedral can be found at about 18 meters in depth. Then you can swim through the cathedral admiring the anemones, and various corals that mark the walls of the cathedral. There are numerous smaller openings to the cathedral allowing plenty light through making the inside of the cathedral stunning majestic and beautiful. There is a exit to the cathedral at about 12 meters. From the exit you can descend around the pinnacle and drop down to 30+ meters and explore the varies underwater terrain. The whole dive is fairly safe and protected from currents so throughout the day no matter the tide it’s a good time to dive Koh Haa Yai Cathedral.
Depth: 12-23 meters (36 – 80 feet)
The last most diverse of the super day dive. Shark point is actually 3 separate pinnacles which are often dived as a drift dive where divers are dropped at shark point 1, then circle and drift down to shark point 2 and 3 where divers are picked up at. The beauty of the various points of shark point dive is that each one is a unique environment to explore. So in 1 dive you can explore 3 separate and diver environments. Shark point 1 is the largest of the 3 points, the top of it’s pinnacle breaks the surface, and proves an easy to find marker for boat captains to find. If the captain times the dive correctly and drops divers as low tide is coming (tide is receding) the tide will carry divers around shark point 1 and to shark point 2/3. Shark point 1 is rich in elk horn corals, seafans and various anemones. Surrounding the central pinnacle there are a number of smaller rocky outcroppings amongst the sandy bottom. Throughout the region there are as you would have guessed it a population of leopard sharks the rest in the sandy bottom. If you dive Shark point there is a 90% chance you’ll see leopard sharks. Shark point 2 is similar in layout and topography to shark point 1, but it’s just much smaller. Shark point 3 is a different dive all together. Shark point 3 is a range of small artificial concrete reefs which are not covered in hard and soft corals and numerous schooling fish can be found circling the reefs. Shark point 1,2 and 3 is included in the ‘super day’ day of SCUBA Diving in Krabi, so if you’re looking for a great day exploring a wonderful underwater landscape, this is the dive day you’ve looking for.
Depth: 10-28 meters (35 – 80 feet)
Made up of one huge pinnacle wish various fissures and cavities carved from it’s interior. The pinnacle is covered top to toe in anemones aptly giving the dive site it’s name. It’s truly magnificent to see as soon as you jump in to the dive, looking down to the top of the pinnacle resting at about 7 meters below the surface and extending down the seafloor at 28 meters. There are numerous anyones to swim through, all along the walls of every canyon you can see hundreds of different colored anemones. The marine life here is a diverse range of moral eels, black tiled reef sharks, green and hawksbill sea turtles, cuttlefish and banded sea kraits. There is nothing more magnificent to see while SCUBA diving in Krabi than the popular anemone reef. Anemone reef is also part of the ‘super day’, yet again another reason to pick this for your day of diving choice if your things of SCUBA Diving in Krabi.
Depth: 18-37 meters (60 – 120 feet)
The King Cruiser was a transport ship who ferried passengers and vehicles to and from Phuket some 40 years ago. It crashed into Anemone reef in 1997 begin to take on water and motored on for another few hundred meters until it found it’s resting place about 2 kilometers off Koh Phi Phi Don. The ferry ship is a large ship around 85 meters in length. The bow of the boat is rich in soft corals, and scorpion fish that slowly drift in and out between the corals. There are a number of places where you can penetrate the boat and enter into the wreck. We recommend you only penetrate the boat while on a wreck diving technical course or if your diving with seasoned wreck divers. Please keep in mind that the wreck is over 30 years old and therefore a good deal of the boat is starting to rot away, so panels and pieces of metal can fall off at anytime. Thats why we recommend you only win around the boat and not into any position where falling debris can hit or injure you or your dive buddy. The bow of the boat rests about 36 meters making it the closest 35+ meter dive site to Ao Nang beach. The stern is is a slightly higher, but the deck of the boat rests about 20 meters below surface. There are schools of barracuda regularly seen at King cruiser, as well as travelies and long finned batfish. A great dive site for any Advanced-open water certified SCUBA Diver, but not recommended for OPEN water divers.
