About Koh Tao
Koh Tao is a small island in the Gulf of Thailand, north of Koh Phangan and Koh Samui. It is one of the world's most popular destinations for scuba diving certification, issuing more PADI certifications than almost anywhere else on Earth. A full Open Water Diver course costs just 9,000-11,000 THB ($250-310), less than half the price of equivalent courses in Australia or Europe. Beyond diving, Koh Tao offers hiking trails with panoramic viewpoints like John Suwan and Fragrant Water, snorkeling at Shark Bay and Mango Bay, freediving schools, and a growing community of long-term expats and remote workers. The main town of Mae Haad has basic amenities including banks, pharmacies, and grocery stores, while Sairee Beach is the social hub with beachfront bars and restaurants.

Getting Around
Koh Tao is accessible only by ferry, with no airport on the island. Lomprayah and Seatran high-speed catamarans are the primary operators, connecting Koh Tao to Koh Samui in about 1.5 to 2 hours, and to Surat Thani's Donsak pier and Chumphon on the mainland. The ferry pier is at Mae Haad on the west coast. Within the island, songthaews meet arriving ferries and run routes to major beaches, with fares typically 50 to 200 THB. For independent mobility, scooter rental is the standard, costing 200 to 300 THB per day or 2,500 to 4,000 THB per month. Koh Tao's roads deserve caution — many are steep, unpaved, and narrow, particularly the routes leading to hillside viewpoints and the southern beaches. Longtails and water taxis operate between beaches during high season for those who prefer to avoid the roads. Walking between Mae Haad and Sairee Beach takes about 20 to 30 minutes along the coastal path.
Healthcare Options
Koh Tao's healthcare facilities are limited, which is an important consideration for long-term residents. The government-run Koh Tao Hospital in Mae Haad provides basic emergency services and routine consultations, though resources and staffing are minimal. Several small private clinics around Mae Haad and Sairee Beach handle common diving-related injuries, minor wounds, and general health concerns. Bangkok Hospital Koh Tao, a private clinic branch, offers somewhat better-equipped care with English-speaking staff. For anything beyond basic care — specialist treatment, advanced diagnostics, or surgery — evacuation to Koh Samui is necessary, where Bangkok Hospital Samui and Thai International Hospital provide comprehensive medical services. Diving-related decompression illness is taken seriously, with evacuation protocols well established. Pharmacies in Mae Haad carry a reasonable range of common medications and first-aid supplies. Comprehensive health insurance covering emergency evacuation by speedboat to Koh Samui or airlift to Bangkok is essential for anyone living on Koh Tao.
Community and Social Life
Koh Tao's community is deeply shaped by the diving industry, which creates an unusually tight-knit and international social fabric. The island has one of the highest concentrations of diving professionals anywhere in the world, and the dive shop network serves as the primary social infrastructure. Dive professionals, instructors, and divemaster trainees form the core of the long-term expat community, regularly gathering at beachfront bars along Sairee Beach after daytime dives. Beyond diving, the island offers a growing selection of beachfront cafes and bars that serve as social hubs, particularly along the Sairee Beach strip where places like FIZZ Beach Club and Maya Beach Club draw evening crowds. Freediving and rock climbing communities add further social dimensions. The island's small size means that residents quickly recognize familiar faces, and newcomers are drawn into the social orbit within days. However, the community can feel transient, as many expats stay for one or two dive seasons before moving on.
