Scuba Diving in Thailand - Where to Dive & What to See - Travel Break

Dreaming about scuba diving in Thailand? Whether you are hoping to get a resort dive qualification or your PADI Open Water certification during a honeymoon or holiday, or you are an experienced diver looking for inspiration, scuba diving in Thailand is something that everyone should experience at least once.

Scuba Diving in Thailand

With a tropical climate, diving is excellent most of the year around in Thailand. November to April is the best time, with sharks being more present between February and May. Giant mantas arrive in the Similan Islands during March and April. Many marine reserves close during the rainy season but the Gulf of Thailand is open still accessible during this time.

Whatever your experience level, your resort will help you plan a scuba diving outing that is ideally suited to your needs and preferences. Top sites to enjoy excellent scuba diving in Thailand include the following:

Similan National Marine Park

The Similan Islands offers some of the best diving in Thailand. Within the greater area, there are around 20 different sites to explore, which include swim throughs, channels and gorges. Things to see in this area include a wide variety of corals, plenty of colourful fish, leopard sharks, turtles and plenty of other wonders.

Koh Dok Mai

Between Phuket and Koh Phi Phi, about 90 minutes by boat from Phuket, lies Koh Dok Mai. Highlights here include hidden caves and crevices, walls, moray eels, large soft corals, seahorse and leopard sharks. Night dives can also be arranged for adventure-seekers wanting a truly unforgettable dive.

Chumphon Pinnacle

In the Gulf of Thailand, Koh Tao is well worth exploring. This spot is often used by divers completing their PADI certification. Along the top of the pinnacle, you will find anemone that attracts white moray eels, fish, crabs and shrimp. As you descend deeper, you will see juvenile barracudas, trevallies, bannerfish and plenty more besides – even whale sharks, if you are lucky.

Sail Rock

North of Koh Samui, between Koh Pha Ngan and Koh Tao, you will find Sail Rock – another popular spot for dive schools. The vertical chimney here makes it a favourite with all levels of diver, with a fun ascend. Highlights here include giant moray eels, large groupers, batfish, large schools of yellow fusiliers and, occasionally, whale sharks.

Wherever you decide to explore, you are sure to find that scuba diving in Thailand is an adventure that you will treasure forever.
