Where is the best scuba diving in Phuket?
Phuket is one of Thailand’s most popular diving destinations and for good reason. Warm tropical water, year-round diving, colourful marine life, and easy access to world-famous dive sites make Phuket one of the best places in Southeast Asia to scuba dive.
Whether you are a beginner looking to try scuba diving for the first time or an experienced diver searching for deeper pinnacles, wrecks, and liveaboard adventures, Phuket offers something for every level of diver.
At Aussie Divers Phuket, we run daily Phuket dive trips to local sites including the Racha Islands, Phi Phi Islands, Shark Point, and King Cruiser Wreck, while also arranging Similan Islands liveaboard adventures and private charters.
So, where is the best scuba diving in Phuket?
The answer really depends on your experience level, the type of diving you enjoy, and the marine life you hope to see.
Similan Islands – Phuket’s Most Famous Diving Destination
For many divers, the Similan Islands offer the best scuba diving in Phuket and Thailand.
Located approximately 100 kilometres northwest of Phuket, the Similan Islands Marine National Park is internationally famous for crystal-clear water, dramatic granite boulder formations, and incredible marine biodiversity.
The Similans are best explored via liveaboard trips, allowing divers to visit multiple remote dive sites over several days.
Divers can expect:
- Massive granite boulders
- Swim-throughs and caverns
- Deep pinnacles
- Soft coral-covered reefs
- Exceptional visibility
- Large schools of fish
The Similan Islands are also one of Thailand’s best locations for larger pelagic marine life including:
- Barracuda schools
- Whale sharks
- Manta rays
- Leopard sharks
- Eagle rays
Similan Islands Diving Season
The Similan Islands National Park closes each year during the monsoon season to help protect the marine environment and allow reef ecosystems to recover naturally.
The park is generally open from October or November through until May.
During the green season, no diving trips operate to the Similan Islands.
The Racha Islands – Phuket’s Best Year-Round Diving
The Racha Islands are another major reason divers love Phuket.
Located south of Phuket, Racha Yai and Racha Noi offer some of the island’s most reliable year-round diving conditions.
The Racha Islands are especially popular because of:
- Excellent visibility
- Calm bays
- Warm tropical water
- Easy diving conditions
- Beginner-friendly dive sites
Racha Yai is particularly well suited to:
- PADI Open Water courses
- Discover Scuba Diving experiences
- Refresher dives
- Underwater photography
- Relaxed fun diving
Marine life commonly seen includes:
- Moray eels
- Barracuda
- Blue-spotted stingrays
- Octopus
- Triggerfish
- Reef fish schools
Racha Yai is also home to several artificial reef and underwater attraction projects including:
- Harruby Wreck
- Meditation Wreck
- Underwater museum areas
- Hanuman underwater statue
These structures not only create unique dive attractions but also support marine habitat development and artificial reef growth.
Racha Noi – Bigger Fish and Deeper Diving
While Racha Yai focuses more on relaxed diving conditions, nearby Racha Noi offers a more advanced diving environment.
Here, divers can experience:
- Deeper granite formations
- Stronger currents at times
- Better opportunities for larger marine life
- More advanced dive conditions
Racha Noi occasionally produces sightings of:
- Manta rays

- Giant trevally
For experienced divers, Racha Noi can provide some of Phuket’s most exciting local diving.
Phi Phi Islands – Colourful Reefs and Marine Life
The Phi Phi Islands remain one of Phuket’s most iconic diving destinations.
Located approximately 40 kilometres southeast of Phuket, Phi Phi offers dramatic limestone island scenery above the water and colourful reef diving below the surface.
Popular dive sites include:
- Koh Bida Nok
- Koh Bida Nai
- Palong Wall
- Viking Cave
Divers regularly encounter:
- Blacktip Reef Sharks
- Leopard Sharks
- Turtles
- Barracuda
- Schools of snapper and fusiliers
- Vibrant coral reefs
The Phi Phi Islands are generally best dived during the dry season when sea conditions and visibility are typically at their best.
Shark Point – One of Phuket’s Best Local Dive Sites
Despite the name, Shark Point is not about dangerous sharks.
Instead, it is one of Phuket’s richest marine ecosystems and a protected marine sanctuary.
The site consists of submerged pinnacles covered in:
- Soft corals
- Sea fans
- Reef fish
- Moray eels
- Lionfish
- Schooling fish
Leopard sharks are occasionally seen resting on the sandy seabed nearby.
Shark Point is famous for its biodiversity and remains one of the best scuba diving sites near Phuket for photographers and marine life enthusiasts.
King Cruiser Wreck – Phuket’s Most Famous Wreck Dive
The King Cruiser Wreck offers one of Phuket’s most unique diving experiences.
This former passenger ferry sank in 1997 after colliding with nearby Anemone Reef.
Today, the wreck has become an artificial reef covered in marine growth and schooling fish.
Divers regularly encounter:
- Yellowtail barracuda
- Snapper schools
- Lionfish
- Moray eels
- Scorpionfish
- Crustaceans hiding throughout the structure
However, after many years underwater, the wreck itself has deteriorated significantly.
Large sections have collapsed, penetration is no longer considered safe, and conditions can become challenging with strong currents and reduced visibility, especially around full and new moon periods.
Because of this, the King Cruiser Wreck is best suited to:
- Advanced certified divers
- Divers with recent experience
- Divers comfortable in deeper water and current
Kata Beach – Phuket’s Easy Shore Dive
Kata Beach offers one of Phuket’s easiest and most accessible shore dive sites.
The Kata Beach House Reef is ideal for:
- Beginner divers
- PADI Discover Scuba Diving
- Refresher dives
- Easy shore diving
During the dry season from approximately November to April, conditions are often calm and visibility can be surprisingly good.
Marine life at Kata Beach may include:
- Sea turtles
- Octopus
- Stingrays
- Reef fish
- Juvenile marine life hidden within the reef
Because the site is shallow and easy to access, it provides a relaxed diving environment for newer divers.
Koh Haa, Hin Daeng & Hin Muang – Advanced Diving from Phuket
For experienced divers wanting more advanced offshore diving, Koh Haa, Hin Daeng, and Hin Muang offer some of Thailand’s best pelagic diving.
These sites are generally accessed via private charter or liveaboard trips during the dry season.
Divers may encounter:
- Manta rays
- Whale sharks
- Large schools of fish
- Deep pinnacles
- Strong currents
- Exceptional visibility
Hin Daeng and Hin Muang are particularly famous for dramatic walls covered in soft corals and the possibility of large pelagic encounters.
Visibility at these offshore sites can sometimes exceed 30 metres.
