7 Best Phuket Dive Sites

Shore Diving

The Kata Beach shore dive on the south side of Kata Beach is popular with local diving schools for training as it’s an easy entry and a short swim to the reef. It’s also a very good way to get an idea of what diving in the Andaman Sea is like. It’s a great training area for beginners or those wanting a refresher before moving on to something more advanced. The coral is in good shape and has many colours, and the marine life is rich and diverse. All the usual Indian Ocean fish species are here, and we get unusual nudibranchs, crabs and shrimp, and sand-dwelling animals. There are many moray eel species on the reef as well. You may even be lucky enough to find a frogfish or ghost pipefish. It makes a great, easy night dive as well.

Maximum depth: 9 meters or 30 feet.
Difficulty level: Beginner.
Visibility: 5-10 meters.

Shark Point Area

The Shark Point area has several dive sites east of Phuket, on the way to the Phi Phi Islands. It takes about 90 minutes to get there by dive boat, and the trips depart every morning. Usually, the dive operator will offer two or three dives on the cluster of reefs surrounding Shark Point, including Anemone Reef, King Cruiser Wreck and Koh Dok Mai.

Shark Point itself is a pinnacle that juts out of the water at all tides and grows larger at its base. It’s covered with soft and hard corals, and when you look up, you’ll see clouds of fish. The rock is covered with marine life, including many species of moray eel, both large and small, lionfish, scorpion fish, and even frogfish if you’re lucky. Pipefish are easy to spot. There are beautiful, healthy sea fans to swim around. The name comes from our local shark favourites, the leopard or zebra shark, which sits at the bottom just breathing during the day and actively hunts at night. They have no teeth, they are not dangerous, and they are very approachable as long as you are slow and careful around them. Shark Point is probably the most popular dive site around Phuket.

The King Cruiser Wreck

The King Cruiser Wreck became a dive site in 1997 when this Phi Phi ferry sank after hitting Anemone Reef. No one was injured, and the boat took several hours to sink as one of its damaged pontoons filled up. Over the years, the Japanese ship has undergone lots of changes, with sections of the ship collapsing, including the wheelhouse some years ago. The ship is 85 meters in length with a beam of 25 meters. It used to rise up to 10 meters in depth, but with the collapse of the ship, the dive sites now begin at 18 meters.

It’s a very nice dive site for both wreck and advanced diving courses and is popular with fun divers as it’s one of our deeper local dives. There are clouds of fish overhead, with a good growth of soft coral on her hull, and many species use the nooks and crannies of the wreck for protection from predators. You can still do a small penetration of the wreck from the stern.

Anemone Reef

Anemone Reef lies just north of Shark Point and lies about five meters below the surface, making it a navigational hazard, though easy to find with a map or GPS on board. The site is named for the thousands of anemones that cling to the rocky reef. It’s covered with large sea fans and lovely purple and soft pink corals, making it one of the prettiest local dive sites we have.

Currents are often strong here, so the boat drops you off near the pinnacle; you descend and stay close to the rock, checking the current before starting to explore. You’ll head down into the sand to look for leopard or zebra sharks, which enjoy resting on the sandy bottom during the day. Then, you’ll circle the pinnacle during the dive, making a nice slow ascent to a safety stop for them to surface. There is something nice to see at any depth on this reef.

Koh Dok Mai

Koh Dok Mai, or “flower island” in Thai, is a mushroom-shaped limestone rock typical of the limestone karst formations we are famous for in the region. It’s a small round island which is easy to swim around in one dive. If the currents are mild, it’s easy to make two loops around the dive site. There are some submerged shallow caves in the rock, and it’s covered with soft corals and sea fans. It has the same marine life as the other dive sites in the area and is usually dived on the return journey back to Chalong Bay as the last dive of the day.

Koh Bida Nok and Koh Bida Yai

Phi Phi is an archipelago of islands lying 30 nautical miles east of Phuket and is a popular holiday spot for divers as well as non-divers. It’s one of the most famous places in Thailand. While there are dive shops and hotels on the island of Phi Phi Don, the only way to see all the local dive sites around Phi Phi is by staying overnight on the islands and using local dive shops. If you’re coming from Phuket on a day trip, the two closest and best dive sites to Phuket are Koh Bida Nok (outside island) and Koh Bida Nai (inside island.) It takes about three hours to get to Phi Phi by dive boat, so two dives are really the maximum for the day. Local dive shops also visit these two dive sites.

The Racha Islands

Racha Yai and Racha Noi are islands directly south of Phuket. Racha Yai (Big Racha) is 12 nautical miles south of Phuket, and Racha Noi (Small Racha) is 20 nautical miles south of Phuket. Sometimes, you’ll see Racha spelt as Raja or Raya. Racha Yai offers the best all-weather training sites around Phuket, so you’ll see many diving courses conducted here. Racha Noi is more advanced depending on the specific site. Both islands offer very good visibility year-round, with better visibility during the rainy season from May until October.
