Discover Pattaya’s Underwater World: Wrecks, Reefs, and Islands
Welcome to the ultimate guide to scuba diving in Pattaya. While the Gulf of Thailand might not always boast the 40-meter visibility of the Andaman Sea, veteran divers know a well-kept secret: Pattaya is one of the most reliable, diverse, and exciting year-round diving hubs in Asia.
Led by a PADI Master Instructor with over 5,000 logged dives, Dream Team Divers guarantees an unparalleled underwater experience. Because we have a massive archipelago of islands dotted along the coast, we are uniquely positioned to find the perfect dive site every single day. If the wind blows from the east, we simply navigate to the sheltered western bays. If surface currents pick up, we have a half-dozen protected go-to spots. This consistency, paired with our incredible topographical variety, makes Pattaya unbeatable.
The Crown Jewels of Pattaya: World-Class Shipwreck Diving
The absolute highlight of diving in Pattaya is our unparalleled access to deep shipwrecks. The Royal Thai Navy has decommissioned and scuttled multiple vessels here to create thriving artificial reefs. Today, these massive structures are draped in soft corals, teeming with schools of snapper, fusiliers, and barracuda, and offer the perfect playground for advanced training, underwater photography, and progressive sidemount diving.
Here is an in-depth look at Pattaya’s famous "Big Three" shipwrecks:
HTMS Khram (LSM-469)
The HTMS Khram is the undisputed king of Pattaya’s wrecks. Originally a US Navy Landing Ship Medium built for World War II, it was sunk in 2003 near Koh Phai to serve as an artificial reef. Resting upright at a maximum depth of around 30 meters, with the main deck at roughly 22 meters, this wreck is a masterpiece for advanced divers. The vessel stretches over 60 meters long and has been heavily prepped for safe diver penetration. Exploring the bridge, radio room, and cavernous tank deck offers a thrilling experience, with batfish and massive groupers frequently patrolling the superstructure.
HTMS Kut (LSM-333)
Sunk in 2006 off the coast of Koh Sak, the HTMS Kut is a sister ship to the Khram and shares the same 60-meter Landing Ship Medium design. Sitting upright with the sea floor at 30 meters and the top of the conning tower reaching up to 12 meters, it provides a fantastic multi-level dive profile. The Kut is celebrated for its dense macro life hiding in the coral encrustations, making it a spectacular canvas for underwater photographers. Its wide-open cargo holds provide excellent, safe swim-throughs for those perfecting their wreck diving skills.
HTMS Mataphon (LCU-84)
The HTMS Mataphon is a Landing Craft Utility ship that was sunk in 2012 near Koh Larn. Resting a bit shallower than her sister ships, the Mataphon bottoms out at around 22 meters. While slightly smaller, its open-deck design and shallower profile make it a fantastic, light-filled dive that allows for longer bottom times. It is the perfect introductory wreck for divers taking their first steps into overhead environments or testing out new gear configurations.
Understanding the Pattaya Archipelago: Near vs. Far Islands
Pattaya's dive logistics are divided into two distinct zones. Knowing the difference helps you plan your ideal day on the water with Dream Team Divers.
The Near Islands (The Pattaya Gateway)
Located just 7 to 10 kilometers off the coast of Pattaya Beach, these islands are highly accessible and perfect for introductory dives, Open Water courses, refreshers, and relaxed two-tank morning trips.
-
The Islands: Koh Larn (the largest Coral Island), Koh Sak, Koh Krok, and Koh Nok.
-
Travel Time: A quick 15 to 20 minutes by speedboat, or a relaxed 45 to 60-minute cruise on a standard dive boat where you can enjoy your morning coffee and breakfast on board.
-
What to Expect: Gently sloping sandy bottoms, beautiful coral gardens, and calm conditions ideal for mastering buoyancy and enjoying a laid-back dive.
The Far Islands (The Outer Reefs)
To experience the healthiest coral formations, the best marine life, and the superior visibility the Gulf has to offer, we venture further out. These islands are often marine reserves or navy-controlled zones, meaning they see far less boat traffic.
-
The Islands: Koh Phai (Bamboo Island), Koh Rin, Koh Man Wichai, Koh Klung Badan, and the dramatic underwater rock formations of North Rock and South Rock.
-
Travel Time: These islands sit 15 to 25 kilometers offshore. Expect a fast 30 to 45-minute speedboat ride, or a scenic 1.5 to 2-hour journey each way on a large dive boat, allowing plenty of time for a relaxing lunch between dives.
-
What to Expect: Dramatic rocky drop-offs, underwater pinnacles, small canyons, and vibrant pelagic marine life passing through the deeper waters.
