Koh Tao, or "Turtle Island," is one of Thailand’s top tropical getaways, known for its incredible dive sites and relaxed island vibes. But beyond its beautiful beaches and vibrant coral reefs, this small island has a fascinating history and quirky details that make it even more intriguing. Here are 10 facts you may not know about Koh Tao:
1. Koh Tao Was Once a Prison Island
After the Siamese Revolution of 1932, Thailand changed from an absolute monarchy to a constitutional democracy, and Koh Tao became a political prison. In 1947, the prisoners received a royal pardon and were moved to Koh Phangan and Koh Samui, leaving the island empty again.
The Vietnam War led to a tourism boom in the 1960s and 70s, attracting American GIs and early backpackers exploring the Gulf Islands. Dive trips started from Koh Samui and Koh Phangan, and by the late 1980s, tourism took off. Koh Tao began adding shops, dive huts, and resorts, along with a growing nightlife at Sairee Beach. Larger ferry companies began serving the island, increasing visitors from Bangkok and establishing Koh Tao as a diving hotspot, with lively areas like Sairee Beach and the quieter Chalok Ban Kao.
2. It’s the Scuba Diving Capital of Thailand
Koh Tao is famous for its crystal-clear waters and abundant marine life, making it one of the most popular scuba diving destinations in the world. It’s estimated that Koh Tao certifies more divers each year than almost anywhere else globally, so if you’re looking to get your PADI certification, this is the place!
With numerous dive sites to explore, including famous spots like Chumphon Pinnacle, Southwest Pinnacle and Sail Rock, you'll find yourself surrounded by breathtaking marine life, including sea turtles, whalesharks, and vibrant reef fish. Whether you’re a newbie eager to dive into your first underwater adventure or an experienced diver seeking to enhance your skills, Koh Tao is definely the ultimate bucket list destination for diving lovers!
3. Koh Tao’s Namesake and Sea Turtles
Koh Tao, also known as "Turtle Island," earned its name from local fishermen and early settlers who noticed that the island resembled the shape of a sea turtle when viewed from their boats. Adding to the charm, the waters around Koh Tao are home to both Hawksbill and Green Sea Turtles. These majestic creatures are often spotted by divers and snorkelers exploring the island’s vibrant marine life!
4. It’s Home to a Diverse Marine Ecosystem
Koh Tao’s surrounding waters are teeming with marine life. You can find over 130 species of coral and a range of marine creatures like whale sharks, barracudas, and stingrays. The island is also a hot spot for nudibranch lovers, with a variety of these colorful sea slugs hanging out in the reefs.
5. Koh Tao Has a Hidden Peak
One of the island’s best-kept secrets is the stunning panoramic views from John-Suwan Viewpoint. Hidden away at the southern tip of the island, this spot offers sweeping views of both Thian Og Bay and Chalok Baan Kao Bay. The short hike is well worth the breathtaking sight waiting at the top.
6. It Was Once a Coconut Plantation
Before it became a diving hub, Koh Tao was largely uninhabited and covered in coconut trees. Local families would trade coconuts for other goods with neighboring islands. You can still see remnants of this history with the coconut palms that dot the island.
7. It’s Part of a Marine Conservation Area
Koh Tao is part of Thailand’s effort to protect its marine environments. Organizations such as the New Heaven Reef Conservation Program and Eco Koh Tao work to preserve the island's delicate ecosystem through coral planting and turtle rehabilitation.

9. The Nightlife Is Low-Key but Lively
Though smaller than its neighbors, Koh Tao still knows how to party. Sairee Beach, in particular, lights up at night with fire shows, beach bars, and relaxed gatherings. Unlike the bustling Full Moon parties of Koh Phangan, Koh Tao's nightlife has a more laid-back, chilled vibe.
