Proud to be an Amazing Thailand – “Thailand Gold Expert”

The Krabi area offers some of the best scuba diving in Thailand and even the world with an incredible variety of dive sites.

There are opportunities for divers of all qualification and experience levels, most of which are ideal for day trips with no need for a liveaboard dive experience for those staying in the Krabi area. A number of the dive sites are much further away from Phuket and are more suitable to a liveaboard.

All of the main tourist areas in Krabi and Phuket have dive shops to arrange courses and dive trips.

Phi Phi islands lie within this area and due to the number of dive sites, there are around 20 in that area alone, we have a separate Phi Phi Dive Sites page.

Koh Lanta dive sites also have their own page here which features some of the best diving in Thailand.

King Cruiser Wreck

The King Cruiser was a transport ship that crashed into Anemone Reef in 1997 before final sinking a few hundred metres and less than an hour later. No lives were lost in the wreck which is around 2 km from Koh Phi Phi Don.

The wreck is around 85 metres long and sits between 10 and 37 metres deep. The wreck can be accessed at a number of points but the structure is not sound and should be entered only under extreme caution. This is a dive for advanced and suitably qualified divers only.

The boat has become an artificial reef in places with numerous soft corals attracting scorpionfish. Schools of barracuda, jacks and snapper can also be seen together with trevelies, long-finned batfish, lionfish and, if you are very lucky, a whale shark can be spotted in the area.

The dive can be combined with a visit to Anemone Reef itself which is a large pinnacle covered in anemones which attracts a wide variety of marine life including mray eel, blacktip reef shark, green sea turtles and hawksbill turtles.

The top of the pinnacle is around 7 metres deep and the bottom is at around 28 metres.

Currents tend to be moderate to strong, with visibility averaging between 5 and 15 metres. Water temperature is around 27 to 30 degrees centigrade all year. The best time to dive in the area is November to April. The boat ride is between 2 hours from the Ao Nang area.

One of the best dive sites in the area is three separate pinnacles often dived as part of a drift dive which includes all three. Shark Point 1 is said to resemble a sharks fin hence the name although others say that it gained its name due to the number of Leopard shark that can be seen in the area.

The dive site is suitable for all levels of diver as depths are generally between 8 and 18 metres deep.

The dive starts at Shark Point 1 which has numerous elk horn coral, anemones and sea fans and can be explored fully before heading to Shark Point 2 which is completely submerged around 8 metres deep and covered in soft coral. The sandy bottom here is home to stingray and leopard shark with schools of snappers and fusiliers all around. A further short swim will get you to Shark Point 3 which is very different to 1 and 2.

Currents tend to be moderate to strong, with visibility averaging between 5 and 15 metres. Water temperature is around 27 to 30 degrees centigrade all year. The best time to dive in the area is November to April. The boat ride is between 2 hours from the Ao Nang area.

Ao Nang Local Islands

With just a 10 minute speedboat of 40 minute longtail boat trip, the Ao Nang local islands provide a more accessible dive location with sheer limestone cliffs rising out of the sea adding to the spectacular beauty of the area.

Each of the islands tends to be its own dive site with its own unique features. The area offers some of the best macro diving in the area with seahorses, nudibranchs, shrimp, and pipefish all common and with a bit of luck you can see bamboo shark or blue-spotted stingray. The area also offers some wonderful swim-throughs, caves and caverns for more experienced divers.

Currents tend to be moderate, with depths up to a maximum of 20 metres deep. Water temperature is around 27 to 30 degrees centigrade all year. Visibility is not as good as other areas around Krabi and can be as low as 2 metres and as high as 12 metres. The best time to dive in the area is October to May. The boat ride is between 30 and 40 minutes from the Ao Nang area.

Probably the most popular dive site in the area with depths of 9 to 18 metres and is made up of three separate islands running north to south.

A site where it is best to take your time to explore cracks, crevices and swim-throughs which are often home to some of the best marine life.

Common life includes bamboo shark, bent stick pipefish, scorpionfish, seahorses, banded sea snakes, spiny lobster and if you are lucky, the shy blacktip reef shark. There can also be large school of snapper and the odd large grouper

This can be a popular dive site with divers and snorkellers so can get crowded at times.

A site for more experienced divers as the main attraction is the 50 metre long swim-through that goes through the entire island with the opportunity to surface part way through into a cave.

The tunnel is a nursery for baby blue-spotted stingray which tend to lie on the sandy bottom. The swim-through is also home to pickhandle barracuda. Outside the swim-through there are plenty of pipefish, seahorses and nudibranchs.

The area can experience strong currents.

Koh Talu

Another site with an island spanning swim-through, although shorter than the one at Koh Yawabon. There is also a second, smaller, swim-through worth exploring.

Inside you will see some wonderful nudibranch and flabellina alongside bamboo shark, blue-spotted stingray, damselfish, butterfly fish, digging goby’s and seahorses. There are sometimes barracuda at the entrance to the swim-through and pufferfish can sometimes be spotted.

The site is only suitable for more experienced divers due to the swim-through and currents but dive times can be extended due to the generally shallow depths averaging around 12 metres and only as deep as 16 metres.

Koh Mae Urai

Opposite Koh Talu is this group of pinnacles which can experience strong current and poor visibility. The site has depths from 9 to 16 metres. sometime combined with Koh Talu as a drift dive.

At its best the site is beautiful with its soft coral and seafans.

Chicken Island is one of the main tourist attractions for boat trips but many will be oblivious to the island opposite, Koh Kom, which is an excellent dive site for all levels of diver.

The site has depths ranging from 9 to 16 metres and is made up of a sandy bottom with rocky outcrops. There is a large cave but be careful that you pick one of the larger entrances. Currents can be strong at times.

The area is excellent for spotting blue-spotted stingray, bent stick pipefish, seahorses and nudibranch with leopard sharks also possibly seen.

Two islands separated by a shallow passage with a sandy bottom and rocky outcrops. Popular for snorkelling and is perfect for all levels of divers and is popular with dive schools.

There are large areas of staghorn and table coral alongside the rocks and sand which attracts big eye snapper, silver trevelly, seahorses, blue-spotted stingray, angelfish, bamboo shark and nudibranch as well as the rare red saddleback anemonefish.

One of the best spots to see blacktip reef shark in the area and also home to at least 60 species of coral and many gorgonion seafan. Schools of barracuda can be seen as well as squid and cuttlefish and, in the morning, leopard shark and stingrays are sometimes seen.

The dive site is generally 9 to 16 metres deep.

Popular with snorkellers due to being the closest island to Ao Nang and also being home to a number of blacktip reef shark.

The area is good for macro diving with its range of hard and soft coral, sea fan, sea whips and barrel sponges being home to many forms of maarine life.
