Getting to Know the Wreck Diving Scene in Koh Tao

“The newest wrecks in Koh Tao, which once served as fast attack crafts for the Royal Thai Navy, now provide thrilling opportunities for divers to explore and discover the rich marine life and history hidden beneath the waves.”

Koh Tao, a tiny island in the Gulf of Thailand, has evolved into a hotspot for divers worldwide. Its warm tropical waters and diverse marine life make it an ideal place for diving enthusiasts. Wreck diving, in particular, has become popular due to the island’s intriguing history and the intentional sinking of ships to create artificial reefs.

Three main wreck sites are currently the pride of the island, attracting divers of all levels. These sites are not just a peek into history, but also thriving homes for a broad spectrum of marine life. For divers who want to inject a bit of adventure into their diving experience, the wrecks of Koh Tao are a must.

First and foremost, wreck diving demands a certain level of skill and a deep respect for the underwater world. It’s not just about the excitement of discovery, but also about recognizing and protecting the fragile ecosystems that have grown around these submerged ships.

Why is Wreck Diving in Koh Tao So Popular?

There are several reasons why wreck diving in Koh Tao is so popular. Firstly, the island is located in the Gulf of Thailand, which means the waters are relatively calm. This makes it a great location for diving all year round. The wrecks themselves are also steeped in history, which gives divers a real connection to the past. Every dive is like a journey through time, as divers get to explore ships that once had important roles before they were turned into underwater attractions.

In addition to that, the biodiversity surrounding these wrecks is nothing short of impressive. The structures serve as a safe haven and breeding site for a variety of marine species, turning them into thriving underwater metropolises. Divers can come across everything from tiny reef fish to larger predators such as barracudas and groupers, ensuring that each dive is a unique and thrilling adventure.

What Makes Koh Tao’s Wreck Sites Stand Out

Every wreck site in Koh Tao is special in its own way. Take the HTMS Sattakut for instance. It’s popular for being easy to access and having a well-preserved structure, which is why photographers and beginner wreck divers love it. Plus, it’s near Hin Pee Wee, so you can also visit the dive site to see some corals and schools of fish.

Conversely, the HTMS Suphairin and HTMS Hanhak Sattru offer more challenging dives because of their depth. These sites are ideal for more seasoned divers who want to push their limits while appreciating the splendor of the underwater world. The variety of the sites guarantees that there is something for everyone, no matter their level of experience.

Before we get into the nitty-gritty, let’s highlight the best wrecks that make Koh Tao a paradise for wreck diving. Each of these sites offers a unique experience, promising both thrill and wonder.

HTMS Sattakut – Hin Pee Wee

The HTMS Sattakut is one of the most accessible and popular wrecks in Koh Tao. Originally a US Navy ship, it was transferred to the Royal Thai Navy before being intentionally sunk to create an artificial reef. This wreck is located at a depth of 18 to 30 meters, making it suitable for both novice and experienced divers.

The HTMS Sattakut is unique due to its proximity to Hin Pee Wee. Divers can examine the wreck and then proceed to the nearby reefs, where they may encounter everything from tiny reef fish to larger species.

HTMS Suphairin – No Name

This wreck, which is located close to No Name Pinnacle, is between 24 and 28 meters (79 and 92 feet) deep, with a top elevation of 16 meters (52 feet). This wreck is relatively new, having been sunk in 2023, and is in great shape. Armed with modern weaponry, including Gabriel surface-to-surface missile launchers, this fast attack craft played diverse roles in safeguarding the nation and conducting joint operations with the Naval Special Warfare Division.

HTMS Hanhak Sattru – Aow Mao

The same class as the HTMS Suphairin and located just off Aow Mao dive site on the east coast. After 42 years of service, these ships were decommissioned in 2018 and transferred to the Department of Marine and Coastal Resources for a new mission as part of the Underwater Learning Park and Marine Ecosystem Rehabilitation Project in Surat Thani Province. Their sinking marks a unique fusion of history and marine conservation, offering divers an opportunity to explore the relics of Thailand’s naval heritage.

Other Wrecks

This wreck is a former dive boat that sank in 2010 and lies at 26 – 37 meters just south of Shark Island. It is deeper than the Sattakut, making it suitable for advanced and technical divers. The ship was used for technical diving before being sunk to act as an artificial reef. The MV Trident attracts various marine creatures, such as batfish, schools of barracuda, and huge groupers.

According to local Koh Tao residents, the ship just drew up off shore about a mile north of Koh Tao’s “Mango Bay” and began to slowly sink over the course of the following few hours. The sinking did not injure anyone and it is around 50 meters deep making it accessible for technical divers only.

What to Expect When Diving in Koh Tao

Before you embark on your wreck diving adventure in Koh Tao, it’s important to familiarize yourself with the local diving conditions.

However, conditions can change based on the season and the particular dive site.

It’s worth mentioning that although Koh Tao’s surrounding waters are typically peaceful, some wreck sites may have stronger currents.
