The history of Koh Tao starts as an uninhabited island until the early 1940’s when it was turned into a political prison for prisoners from the Borawadesh uprising on Koh Tarutao. The prison was located in Mae Haad Bay and at its height housed just over one hundred prisoners and about fifteen wardens. Life wasn’t easy for the prisoners as food was scarce and malaria was rife. By the mid 1940’s, the prisoners were released and everyone went back to the mainland. Within a couple of years Koh Tao had largely become an uninhabited island once again.
By 1950, two brothers from Koh Samui sailed over to Koh Tao on a traditional Thai boat with two masts and handmade sails. They cleared some land and used what was left of the prison as a temporary shelter. By 1953, others from Koh Phangan arrived on the island searching to start a new, simpler life, on the island shaped like a turtle when viewed from afar.
In the late 1970s, a handful of adventurous backpackers began to explore the untouched beauty of Koh Tao. Word quickly spread about the island’s serene ambiance, stunning coral reefs, and abundant marine life. This newfound reputation led to the establishment of the first dive shops on the island, marking the birth of the dive industry.
Among the pioneers of the dive industry in Koh Tao was an Italian who would bring divers over from Koh Samui for an overnight diving trip to Koh Tao. He found the Red Rock, White Rock, and Green Rock dive sites, naming them after the three colors of the Italian flag. He also founded the first dive school on Koh Tao, and imaginatively called it Koh Tao Divers. The potential of the island as a diving destination was established and gradually Koh Tao started organizing dive tours and training programs for visitors.
And it was right about now in these early days of Koh Tao a tall intrepid backpacker from Sweden, found himself sitting on a coconut boat from the mainland. Upon arriving on Koh Tao he enrolled in his Open Water Course and loved it so much he went almost as far as Divemaster before he ran out of money. Never the one to be put off by problems Michael, whizzed home to Sweden, got a bank loan to buy a car, then jumped back in the plane to Thailand & with this loan started the second Dive shop on Koh Tao – Big Blue Diving, and then went on to complete his Divemaster course!
These early dive pioneers focused on providing basic diving courses, such as Open Water Certification, to cater to the growing interest in underwater exploration. And as Koh Tao’s reputation as a dive destination grew, more dive operators and resorts began to sprout up on the island. This surge in infrastructure development brought about an increase in the number of dive sites explored. With its proximity to the famous Chumphon Pinnacle, Sail Rock, and the dive sites around Nang Yuan Island, Koh Tao offered divers a variety of underwater landscapes to discover.
The success of the dive industry in Koh Tao can also be attributed to the island’s natural resources. Its warm tropical waters, diverse marine ecosystem, and stunning coral reefs provided an ideal environment for both beginners and experienced divers. The island’s abundant marine life, including colorful coral formations, tropical fish, and even occasional sightings of whalesharks and turtles, added to the allure of diving in Koh Tao.
Over time, Koh Tao’s dive industry expanded beyond just dive courses and certifications. Dive shops began offering specialized training programs, such as advanced diving courses, technical diving, freediving and even Instructor Development Courses. This diversification of offerings attracted a wider range of divers, from casual enthusiasts to those seeking professional careers in the diving industry.
The development of the dive industry in Koh Tao has had a significant impact on the island’s economy and infrastructure. As more divers flocked to the island, accommodations, restaurants, and other tourism-related businesses flourished. The local community benefited from increased job opportunities and a growing economy.
However, the rapid growth of the dive industry also brought challenges. The influx of divers and tourists placed strains on the island’s resources and ecosystem. To address these concerns, various environmental initiatives were introduced to promote responsible diving practices, coral reef conservation, and waste management. Today, dive operators in Koh Tao actively participate in reef monitoring, underwater cleanups, and educational campaigns to ensure the sustainability of the marine environment.
In recent years, Koh Tao has become one of the world’s most popular destinations for diving certifications. The island’s accessibility, affordability, and reputation as a safe and reliable place to learn to dive continue to attract thousands of divers each year. Dive centers and resorts now offer a wide range of diving experiences, from day trips to tech expeditions, catering to the diverse needs and preferences of divers.
