The diving-community pace of life, boat and ferry access, banking, connectivity, groceries, and a full map to every practical Koh Tao guide -- this island has a genuinely deep library of them.
Koh Tao runs on a compact, dive-shop-centred rhythm rather than a city pace. Most residents live within a short scooter ride of everything they need -- work, food, groceries, healthcare and social life -- concentrated around Sairee Beach, Mae Haad and Chalok Baan Kao. This page pulls together the practical basics of everyday life, then routes you to the dedicated deep-dive guide for every topic BAANLYY has built for this island. Start with the Koh Tao hub for the province-wide overview, or the where-to-live guide if you have not yet picked an area.
Diving is not just a pastime here -- it is the island's core industry and its main social structure. Dive shops double as informal community hubs, employers and social circles, and much of the island's rhythm follows dive-boat schedules and course calendars rather than a conventional 9-to-5. Facebook groups and Messenger are the practical backbone of daily organizing -- housing listings, buy-and-sell posts, and island news mostly circulate there rather than through any formal local press. It is a young, active, transient-leaning community: many residents arrive for a course or a season and stay far longer than planned, and turnover among the expat population is genuinely higher than in Thailand's larger, more settled expat hubs.
Koh Tao has no airport of its own, so every route in or out ends with a ferry. The two standard approaches are via Chumphon on the mainland (reached by train, bus or a flight into Chumphon airport, then a ferry commonly cited at roughly two to three hours) or via Koh Samui, which functions as the region's main transport hub thanks to its own airport, larger hospitals and bigger supermarkets. Plan around ferry schedules and sea conditions rather than mainland-style fixed timetables -- rougher weather, especially in the reversed monsoon window covered in the flood-risk guide, can delay or cancel sailings. See the full airport-transfer guide for route-by-route detail and current operators.
Everyday banking is handled locally. ATMs are widely available near the piers and around central Sairee, and Mae Haad has currency exchange shops, local bank branches and Western Union services for anyone sending or receiving money internationally. Opening a Thai bank account is possible on-island but the exact requirements (visa type, proof of address, sometimes a work permit) vary by bank and branch -- see the full banking guide for which banks operate here and what to bring.
All three major Thai networks -- AIS, True Move and dtac -- operate on Koh Tao. A basic True Move prepaid SIM is commonly picked up from a 7-Eleven for a small upfront cost, while AIS and dtac are more often handled through a dedicated phone shop on the island. Bring your passport regardless of provider, since SIM registration is legally required in Thailand. Home and cafe wifi quality varies by area and building -- see the internet-sim guide for current provider and coverage detail, and the coworking-spaces and cafes-and-wifi guides if you are working remotely.
7-Elevens across the island cover convenience basics, while dedicated grocery shops -- names residents commonly mention include Pen Market, Chaiwat and Smile Mart -- carry a wider range, including imported items for anyone missing a taste of home. Selection is naturally more limited than on the mainland and prices run somewhat higher, since most goods arrive by boat rather than truck. See the shopping-markets guide for an area-by-area breakdown, and the restaurants guide for eating out.
BAANLYY has built genuinely deep, dedicated guides for Koh Tao across dozens of practical topics -- this page is the map, not a replacement for any of them.
Compact, scooter-scale and dive-shop-centred. Most daily essentials -- cafes, gyms, dive shops, cowork-friendly spots and groceries -- cluster around Sairee Beach, Mae Haad and Chalok Baan Kao, so most residents live within a short scooter ride of everything they need. The island runs on a diving-community rhythm: dive shops are the social and economic anchor, and Facebook groups and Messenger are how most people actually organize housing, buy and sell things, and hear island news, more than any formal local press or noticeboard.
There is no airport on Koh Tao itself. The standard routes run via a mainland pier (commonly Chumphon, reached by train, bus or flight to Chumphon airport) or via Koh Samui, which functions as the region's main transport hub with its own airport, larger hospitals and bigger supermarkets. Whichever route you take, the final leg is a ferry -- commonly cited at roughly two to three hours depending on the boat and conditions. See the full airport-transfer guide for route-by-route detail.
Yes, both are handled locally in Mae Haad and Sairee. Banking: ATMs are widely available near the piers and in central Sairee, alongside currency exchange shops, local bank branches and Western Union services -- see the full banking guide for which banks have branches and what opening an account involves. SIM cards: AIS, True Move and dtac all operate on the island; a basic True Move SIM is commonly available from 7-Eleven for a small fee, while AIS and dtac are typically handled through a dedicated phone shop -- bring your passport, since SIM registration is mandatory in Thailand. See the internet-sim guide for current provider comparisons.
A mix of 7-Elevens for convenience basics and dedicated grocery shops -- names commonly mentioned by residents include Pen Market, Chaiwat and Smile Mart -- for a wider range including imported items. Selection and pricing are naturally more limited and pricier than on the mainland, since almost everything arrives by boat. See the shopping-markets guide for area-by-area detail.
It's built primarily around diving, remote work and a young, active expat community rather than family infrastructure -- though the island does have some school and childcare options, covered in the dedicated schools and childcare guides. If dense international schooling and hospital infrastructure are non-negotiable, weigh Koh Tao honestly against Koh Samui, which sits a ferry ride away and has considerably deeper infrastructure on both fronts.
