A small Gulf-of-Thailand island and the country's top scuba and snorkeling spot — the world's cheapest place to get PADI-certified, the iconic Koh Nang Yuan sandbar, Sairee Beach sunsets, the John-Suwan viewpoint, sea turtles and blacktip reef sharks, all reached by ferry from Chumphon or Koh Samui
Koh Tao is a small island in the Gulf of Thailand, in Surat Thani province, long known as Thailand's diving capital — one of the cheapest places in the world to get PADI-certified, with clear water, healthy reefs and frequent sightings of sea turtles and blacktip reef sharks. Snorkel around the three islets of Koh Nang Yuan, climb to the John-Suwan viewpoint, watch the sunset from Sairee Beach, and settle into the island's easy, laid-back pace — all reached by ferry from Chumphon or Koh Samui.
Koh Tao is small and easy to get around. Most visitors base themselves in one of four areas — buzzy Sairee Beach, the central pier town of Mae Haad, quiet Chalok Baan Kao in the south, or the secluded east-coast bays. Pick the one that matches what you came for.
The island's main beach and social hub — the longest stretch of sand, lined with dive shops, restaurants, sunset bars and the busiest nightlife. Everything is walkable and lively after dark.
Where the ferries dock — the island's central village, with banks, cafés, restaurants and dive centres. Convenient and well-connected, an easy walk to Sairee just to the north.
A mellow southern bay away from the Sairee crowds, with a relaxed beach and easy access to the John-Suwan viewpoint and Shark Bay. Calmer evenings, but still plenty of places to eat.
Secluded east-coast coves like Tanote Bay and Thian Og (Shark Bay), where resorts sit right above the reef. Snorkel straight off the beach and escape the crowds — bring a scooter or use a taxi-boat.

Mid-to-luxury bungalows scattered across the headland at the north end of Sairee, with private beach coves and sweeping sunset views over the bay.
Rustic-romantic villas tumbling down a hillside to its own quiet snorkeling bay just south of Mae Haad — a long-time favourite for couples.
The island's best-known dive-and-stay resort, right on Sairee Beach — budget rooms bundled with PADI courses, plus two pools and a beachfront bar.
A dramatic clifftop resort and spa above Thian Og (Shark Bay), with carved-stone villas, an infinity pool and some of the island's finest sea views.
A relaxed resort on the soft sand of Shark Bay, where green turtles and reef sharks cruise the shallows — snorkel straight off your own quiet east-coast beach.
Wooden cottages set in a tropical garden right by Mae Haad pier — steps from the ferry, restaurants and dive shops, yet quiet and green by the water.

Koh Tao's food scene runs from just-landed Gulf seafood to easygoing international cafés built around the diving crowd. From beach barbecues to smoothie bowls, here is what you absolutely cannot miss.
Prawns, squid and whole fish straight from the Gulf of Thailand, grilled over charcoal and served with spicy seafood dipping sauce. The island's signature meal, best eaten by the water.
Signature DishA whole sea bass steamed in a sharp, garlicky lime-and-chilli broth — fresh, fiery and tangy. A Thai seafood classic you'll find on almost every island menu.
Seafood ClassicAs the sun goes down, Sairee's beachfront restaurants lay out nightly seafood barbecues — pick your fish from the ice, grab a table on the sand and watch the sunset. The quintessential Koh Tao dinner.
Sunset DinnerSmoothie bowls, fresh juices and plant-based plates fuel the island's divers and yoga crowd. Koh Tao has one of Thailand's best little health-food and vegan café scenes for its size.
Healthy EatsYears of dive travellers have left Koh Tao with great wood-fired Italian, Mexican, burgers and more, scattered across the island — easy comfort food between dives.
Global FlavoursSpecialty coffee, cakes and bay views make Koh Tao's seaside cafés the perfect place to relax on a surface-interval afternoon. Many double as sunset spots once the day winds down.
Coffee & CakeKoh Tao pairs the world's best-value diving with photogenic islands, clifftop viewpoints and shallow coral bays you can snorkel straight from the sand. Here are the sights you shouldn't miss.
Three tiny islets joined by a dazzling triple sandbar — the island's signature view. Climb the short trail to the lookout, then snorkel the clear water on either side. Koh Tao's most iconic photo.
Island LandmarkKoh Tao is one of the cheapest places in the world to get certified — a PADI Open Water course runs 2–3 days, often with accommodation thrown in. 20+ dive sites circle the island.
World's Best-Value DivingA short, steep climb above the southern capes rewards you with a twin-bay panorama — arguably the best view on the island, and unbeatable at golden hour.
Best ViewpointThe island's longest beach and beating heart — dive shops, restaurants and bars line the sand, and everyone gathers here for the sunset. The place to base yourself and unwind.
Main BeachA sheltered east-coast bay famous for its big boulder and jump rock, with easy reef snorkeling right off the beach. One of the calmest, clearest spots to get in the water.
Snorkeling BayA shallow southern reef where green sea turtles graze and harmless blacktip reef sharks patrol the shallows. Snorkel from the beach for a near-guaranteed turtle sighting.
Turtles & Reef SharksTwo days is a great first taste of Koh Tao — day one for Koh Nang Yuan and the snorkeling bays, day two for a dive or the John-Suwan viewpoint and a Sairee sunset. Easy to tweak to your own pace (add a day or two if you're taking a dive course).
Essential info and getting-around tips to help your Koh Tao trip run smoothly from the very first ferry.
There's no airport on Koh Tao — you arrive by ferry. From the mainland, take a train or bus from Bangkok to Chumphon, then a high-speed catamaran (~1.5–3 hrs). Ferries also run from Koh Samui and Koh Phangan.
Carry cash — many small bars and beach spots are cash-only. Cards and PromptPay QR work at bigger resorts and dive shops, and there are ATMs in Sairee and Mae Haad (expect a per-withdrawal fee).
Pickup taxis run set routes, taxi-boats hop between bays, and many people rent a scooter — but the steep, rough roads are no place for first-timers. Sairee and Mae Haad are easily walkable.
Pick up a tourist SIM (AIS, TrueMove or dtac) on the mainland, or activate an eSIM before you travel. 4G coverage is good around the main bays, patchier on the remote east coast.
