Diving in Thailand

Quick facts

At the heart of Southeast Asia, Thailand, the "Land of a Thousand Smiles," is a country proud of its unique culture and famous worldwide for its cuisine. You’ll find palm fringed white sand beaches, colourful coral reefs and many exhilarating cultural attractions in some of Southeast Asia’s liveliest cities.

With the Gulf of Thailand on the east and the Andaman Sea on the west, diving opportunities include fringing reefs, deep drop-offs, wrecks, walls, caverns, tunnels, pinnacles or open ocean seamounts. In the evenings, you’ll find entertainment varies from phenomenal dining and chilled out sundowners to night clubbing and lively full moon parties.

Dive sites are a rainbow of colours and teeming with marine life. For “big fish” aficionados, whale sharks, manta rays, leopard sharks and other pelagics are a major draw whilst macro-life such as seahorse, frogfish, ghost pipefish and an array of nudibranch and crustaceans can all be seen amongst the reefs.

Recommended training

Thailand is a great destination to learn to dive with the PADI Open Water Diver course. If you are already PADI certified, look to take the PADI Enriched Air, PADI Deep Diver and PADI Drift Diver courses so you’re prepared for diving the many pinnacles and walls across this destination. The PADI Wreck Diver course is a natural if you plan to dive any of Thailand’s amazing wrecks. Thailand is also an excellent location to become a PADI Pro by taking the PADI Divemaster course or the PADI Open Water Scuba Instructor course.

Country

The ‘land of smiles’, Thailand welcomes tourists to its lush tropical shores in droves. Indeed, there is much to offer no matter your budget or what you look for in a holiday. Thailand excels at beautiful beaches and, of course, some fabulous snorkelling and diving.

Topside there's the tasty food, huge shopping malls, great nightlife and spas, wellness and spirituality as a counter balance. You can rock climb, and you can hike in national parks with rugged and lush scenery. Culturally there are some fabulous festivals and superb temples and historic sites.

Tourism has brought with it modernisation, but Thailand has still retained its exotic and unique charms. It’s as much pleasure to visit today as it was 30 years ago, although with somewhat easier connections, swifter travel and faster internet.

Other attractions

Bangkok offers connections all over Asia, which makes it very easy to take in great attractions in the region as part of a multi-centred trip. Some choose to shop in Singapore while others might choose the awesome temple complex of Angkor in neighbouring Cambodia.

Getting there

Suvarnabhumi International Airport located in Bangkok is the main gateway to the country and most likely where you will land. Don Muang International Airport is the old main airport also located in Bangkok. This airport mainly serves the budget, domestic and regional international connections. You can get anywhere from Bangkok.
