With iconic sites like the HTMS Khram, HTMS Kut, and the Hardeep, divers of all skill levels can explore the beauty of the underwater world while experiencing the history and mystery of these sunken relics. These wrecks are now artificial reefs that have transformed into thriving underwater ecosystems teeming with diverse marine life.
In this article, we’ll dive deep into everything you need to know about Unforgettable Wreck Diving in Pattaya—from the history of these wrecks to the marine life that calls them home, along with tips for making the most of your adventure.
HTMS Khram: A Diver’s Delight
History and Location
The HTMS Khram, a former U.S. Navy vessel, was built during the mid-20th century and served during the Vietnam War before being decommissioned. After its service, it was donated to the Royal Thai Navy and eventually scuttled in 2003 as part of a marine conservation effort to create an artificial reef.
Located just 30 minutes by boat from Pattaya, the HTMS Khram sits upright at a depth of 30 meters, making it an accessible site for advanced divers. The ship was carefully prepared for diving, with open sections allowing easy exploration and penetration while ensuring safety.
Dive Highlights
The HTMS Khram offers an array of features that make it an unforgettable wreck diving experience in Pattaya:
- The Wheelhouse: Explore the captain’s quarters and wheelhouse, which provide incredible panoramic views of the surrounding marine life and sea floor.
- The Engine Room: Perfect for divers certified in wreck penetration, this area showcases the heart of the vessel, now encrusted with coral.
- The Deck: Covered in soft corals and sponges, the deck is alive with vibrant fish and invertebrates, offering plenty of photographic opportunities.
- Cargo Holds: The wide-open spaces of the cargo holds make them ideal for practicing wreck navigation techniques.
Marine Life
The HTMS Khram has become a vibrant artificial reef, attracting an astonishing variety of marine life:
- Large schools of pelagic fish, such as trevally, fusiliers, and barracuda, frequently circle the wreck.
- Moray eels and giant groupers hide in crevices, adding a sense of mystery to the dive.

- Seasonal sightings of whale sharks have been reported, offering a thrilling surprise for lucky divers.
- Smaller critters like ghost pipefish, mantis shrimp, and crabs often scuttle across the sandy seabed near the wreck.
HTMS Kut: A Playground for Wreck Enthusiasts
History and Location
The HTMS Kut served as a patrol boat for the Royal Thai Navy before being retired. In 2006, it was intentionally sunk as part of Thailand’s ongoing efforts to establish artificial reefs for marine conservation and as a unique diving attraction.
Situated in waters around 27 meters deep, this wreck is slightly smaller than the HTMS Khram, making it ideal for intermediate wreck divers or those looking to refine their skills. Its compact size and upright position provide a manageable yet exciting dive experience.

- Open Hatches and Hallways: These features make the Kut an excellent training ground for divers developing wreck navigation and penetration skills.
- Abundant Coral Growth: Coral-encrusted railings and structures provide stunning scenery and excellent photography opportunities.
Marine Life
The HTMS Kut is alive with marine creatures that make every dive an adventure:
- Batfish, angelfish, and wrasse dart around the exterior of the wreck.
- Seahorses and pipefish can be spotted clinging to coral-covered surfaces.
- Predator species like trevally and barracuda cruise the area, hunting smaller fish.
- Lionfish and scorpionfish hide along the wreckage, making them challenging but rewarding subjects for photographers.
- Look closely to find octopuses and cuttlefish camouflaged against the wreck.
- Nearby sandy areas are home to bottom-dwellers like flounders and stingrays.
The Hardeep: A Dive Into History
History and Location
The Hardeep, also known as the S.S. Suddhadib, has a storied past. This steam-powered cargo ship was sunk during World War II after being bombed by Allied forces. Unlike the HTMS Khram and Kut, which were scuttled for conservation, the Hardeep carries a rich historical legacy.
The wreck lies on its side at depths ranging from 21 to 28 meters near Samae San, a short boat ride from Pattaya. Its unique orientation and wartime history make it one of Thailand’s most fascinating wreck dives.
Dive Highlights
- Sideways Orientation: The ship’s tilted position offers a unique perspective for exploration and photography.
- The Hull: Vibrant soft corals cover the hull, creating a mesmerizing spectacle.
- The Cargo Hold: This spacious area still contains remnants of the ship’s cargo and machinery.
- Strong Currents: The currents around the Hardeep add a layer of excitement and challenge for experienced divers.
Marine Life
The Hardeep hosts an extraordinary range of marine life, making it an unforgettable wreck diving experience in Pattaya:
- Soft corals in vivid hues of pink, orange, and purple cover much of the wreck.
- Schools of bannerfish, butterflyfish, and snapper swarm the area.
- Scorpionfish, stonefish, and porcupinefish blend seamlessly into their surroundings.
- Night dives often reveal cuttlefish, squid, and nocturnal shrimp.
- Turtles have been spotted grazing on nearby reefs, adding to the dive’s charm.
Marine Conservation and Responsible Diving in Pattaya
How Wrecks Like the HTMS Khram Contribute to Marine Conservation
The decision to scuttle vessels like the HTMS Khram and HTMS Kut wasn’t just for the thrill of wreck diving—it was a carefully planned marine conservation strategy. These wrecks act as artificial reefs, creating new habitats for marine life and fostering biodiversity in areas where natural coral reefs have been damaged or are absent.
- Providing Shelter for Marine Life
- The sunken structures offer shelter to fish and invertebrates, protecting them from predators. Spaces like cargo holds, engine rooms, and wheelhouses provide safe environments for species like moray eels, grouper, and lionfish.
- Cracks and crevices in the wreck attract smaller species, such as blennies, shrimp, and nudibranchs, essential for maintaining the food chain.
- Promoting Coral Growth
- Over time, wreck surfaces become encrusted with corals, sponges, and algae. These growths form the foundation of an ecosystem, attracting herbivores like parrotfish and creating a symbiotic environment for other marine life.
- The diverse coral communities also improve the overall health of the surrounding waters by stabilizing marine populations.
- Reducing Pressure on Natural Reefs
- Artificial wreck reefs alleviate stress on natural coral reefs, which are often over-dived or damaged. By diverting divers to sites like the HTMS Khram and Kut, these wrecks play a key role in conserving Pattaya’s delicate coral ecosystems.
- A Platform for Marine Research
- Pattaya’s wrecks provide opportunities for marine biologists and conservationists to study reef formation, fish behavior, and coral recovery in controlled conditions.
Tips on Responsible Diving Practices
Marine conservation doesn’t stop at creating artificial reefs—divers play a vital role in preserving these ecosystems. Adopting responsible diving habits ensures that Pattaya’s underwater treasures remain vibrant for future generations.
- Respect Marine Life
- Avoid touching or disturbing marine life. For example, delicate corals can die from the oils on human skin, and handling creatures like seahorses or nudibranchs can stress them significantly.
- Give marine animals space. Whether it’s a grouper resting in the cargo hold or a whale shark cruising by, observing from a distance minimizes disruption.
- Avoid Touching Wreck Surfaces
- Wreck surfaces are often covered with corals, sponges, and other delicate organisms. Kicking up sediment or grabbing onto surfaces can harm these fragile ecosystems.
- Maintain proper buoyancy to avoid accidental contact with wrecks or the sea floor.
- Use Reef-Safe Products
- Opt for reef-safe sunscreens and avoid chemical-based products that can leach into the water and damage marine ecosystems.
- Don’t Litter
- Always secure your equipment and avoid leaving trash behind. If you see marine debris during your dive, consider collecting it safely.
- Support Eco-Friendly Dive Centers
- Choose dive centers that follow sustainable practices, such as limiting group sizes, using eco-friendly gear, and engaging in reef restoration projects.
By adopting these practices, divers can actively contribute to Pattaya’s marine conservation efforts while enjoying the unforgettable wreck diving experience this destination offers.

How to Become a Wreck Diving Expert
Wreck diving offers a unique combination of history, mystery, and adventure. While exploring these underwater relics is thrilling, becoming a true expert requires skill, knowledge, and the right training. If you’re ready to elevate your diving experience and unlock the full potential of wreck exploration, here’s how you can progress from recreational diving to mastering the art of wreck diving.
1. Master the Basics: Wreck Diver Specialty Course
The PADI Wreck Diver Specialty Course is the foundational step for anyone interested in wreck diving. Designed to teach the essential skills and safety techniques for exploring submerged vessels and structures, this course combines classroom instruction with practical in-water training.
What You’ll Learn:
- Wreck Navigation Techniques: Learn how to safely navigate the outside and inside of wrecks using reference points, lines, and natural landmarks.
- Wreck Mapping: Practice creating basic maps of wreck sites to improve orientation and planning.
- Safe Penetration Practices: Develop skills to explore the interior of wrecks safely, including using reels and guidelines to avoid getting lost.
- Avoiding Hazards: Learn how to recognize potential dangers, such as unstable structures, sharp objects, and poor visibility.
- Preservation Awareness: Understand how to dive responsibly, preserving the wreck and its marine life for future divers.
Requirements:
To enroll, you must already hold an Advanced Open Water certification. The course typically includes four dives, with some focused on external navigation and others on interior penetration.
Why It’s Important:
This course not only enhances your wreck diving skills but also boosts your confidence underwater. It opens the door to more advanced wreck diving opportunities and helps ensure your safety during these potentially challenging dives.
2. Enhance Your Bottom Time: Enriched Air (Nitrox) Certification
One of the key challenges in wreck diving is the limited bottom time due to depth. By becoming Nitrox certified, you can extend your time exploring wrecks like the HTMS Khram and Hardeep while staying within safe no-decompression limits.
What You’ll Learn:
- Understanding Nitrox: Learn the benefits of diving with air enriched with higher oxygen levels (commonly 32% or 36%).
- Dive Planning: Master how to plan dives using Nitrox to maximize bottom time and reduce nitrogen absorption.
- Analyzing Tanks: Learn how to test and confirm oxygen levels in your dive tank.
Why It’s Important for Wreck Diving:
Many wrecks in Pattaya, like the HTMS Khram (30 meters) and Kut (27 meters), are at depths where standard air limits your dive time. Nitrox allows you to safely extend your exploration of these deeper wrecks, giving you more time to take in the details and capture stunning underwater photos.
3. Progress to Technical Wreck Diving
Once you’ve mastered recreational wreck diving, the next step is technical diving. Technical wreck diving allows you to explore deeper, stay longer, and penetrate further into wrecks.
