Built from over 20 years on Koh Tao

Koh Tao is a small tropical island in the Gulf of Thailand, Surat Thani province. No airport — everyone arrives by ferry from Chumphon, Koh Samui or Koh Phangan. Famous for scuba diving, whale sharks at Chumphon Pinnacle, and a pace that makes a week feel like a month in the best possible way.

Crystal-clear water, vibrant coral, scenic viewpoints, a slow island pace. Small enough to know in a week. Deep enough to keep coming back.

This guide is what we’d tell a friend flying in. Built from 20+ years living and working on the island.

Activities

Best things to do in Koh Tao

One of the main reasons travellers fall in love with the island is the wide range of activities available. Ocean adventures, scenic hikes, late-night bars, plenty for every type of traveller.

Especially famous for scuba diving, with dozens of dive schools running courses for beginners and guided dives for the more experienced. If diving isn’t your thing, snorkelling, island tours and stand-up paddleboarding give the same blue water without the gear.

Best for: first-time divers, snorkellers and anyone planning the days around water.

Places

Beaches, viewpoints, Koh Nang Yuan

Koh Tao used to be known purely for diving. Now it is just as likely to be the place where you lose a few days to good beaches, late nights and people you just met. Most visitors come for one thing and end up doing more.

The bays change character with where you are. Sairee for liveliest, Freedom and Shark Bay quieter, Tanote and Hin Wong for solitude. Koh Nang Yuan a short boat ride from Mae Haad, three small islands connected by a sandbar with a viewpoint worth the climb.

Best for: picking the right beach base for your trip.

Where to stay

Where you stay shapes the trip

The different areas offer very different experiences. Choose the wrong one for your style and you will feel it. Mae Haad for ferry-day convenience, Sairee for the centre of things, Chalok Baan Kao for slower pace, the east coast for quiet.

Budget hostels mostly cluster around Sairee. Bungalows, resorts and villas spread across the island depending on area and setting. From 250 THB hostel dorms to 8,000+ THB private bungalows, there is a fit for every kind of trip.

Best for: deciding which area before you book a single room.

Food & Nightlife

Where to eat and drink

Food and nightlife are a bigger part of the experience here than most people expect. Cheap Thai street food, casual beach spots, proper sit-down restaurants, international cuisine, late-night bites after a long evening out.

Mornings are easy. Cafes and breakfast spots are scattered across the island, good coffee, fresh fruit, smoothie bowls. Evenings shift the energy. Sairee is the centre of it, bars, live music, venues that run well past midnight most nights of the week.

Best for: finding your pace, whether you eat well or go out hard.

Plan your trip

A little planning goes far

Knowing when to come, how to get around and what to expect when you arrive makes the difference between a smooth trip and a frustrating one. The time of year matters more than people think, sea conditions, weather and dive visibility all shift with the season.

It also helps to have a basic sense of costs and how transport works before you get here. Nothing complicated, just enough to arrive prepared and spend your time enjoying it.

Best for: month-by-month weather, budget bands and itinerary structure.

Transport

Boats, scooters, longtails

Koh Tao is a boat-only island. No airport, no bridge. Everyone arrives by ferry or speedboat, and getting here is straightforward once you know the route from where you are coming.

On the island, getting around is easy. Most rent a scooter for the freedom to reach different beaches and viewpoints on their own schedule. Songthaew pickups and longtail boats cover the rest.

Best for: building your route from Bangkok, Phuket or Samui to Mae Haad.

FAQ

Questions travellers ask us

Quick answers to the things that come up most. Every link goes to the deeper page if you want more.

What is the best time to visit Koh Tao?
It depends on what you want to do. High season runs mid-December to February, calmest seas and highest prices. Shoulder seasons March to May and September to October balance thinner crowds with workable weather. November to early December is the monsoon window, more cancellations and cheaper rooms. See our Plan Your Trip guide for month-by-month notes.
Is Koh Tao good for scuba diving?
Yes. It is one of the most popular places in the world to learn. Courses are affordable, conditions are generally accessible, and there are plenty of dive sites for all levels. You can explore options in our Scuba Diving guide.
How many days are enough for Koh Tao?
Most people stay longer than planned. Four to seven days is a good balance if you want to dive, explore different beaches and enjoy the island without rushing. If you are not sure how to structure your time, check our Plan Your Trip page for itinerary ideas.
How do you get to Koh Tao?
The island is only accessible by boat. Most routes involve a ferry from the mainland (Chumphon or Surat Thani) or nearby islands like Koh Samui and Koh Phangan. You can find routes, schedules and options in the Ferry guide 2026.
Is Koh Tao safe for tourists?
Yes. Despite the headlines that occasionally surface, Koh Tao is a small town where hundreds of thousands of tourists pass through every year without incident. Standard small-island sense applies, drive scooters carefully, watch your drinks, buy travel insurance. As safe as anywhere in rural Thailand and considerably safer than most large cities.
Is there good wifi for remote work?
Yes. Fibre internet is standard in most Sairee and Mae Haad accommodation, 50 to 200 Mbps is common with some stays hitting 300+. Two dedicated coworking spaces operate on the island, plus several work-friendly cafes. Full 4G and 5G coverage from AIS, True and DTAC island-wide.
Do I need a visa to visit Koh Tao?
Most nationalities get a free visa exemption on arrival in Thailand — 30 days for most countries, 60 days for several including USA, UK, EU, Australia and Canada since 2024. Check the Thai immigration website for your specific passport. Koh Tao itself has no border checkpoint; your entry stamp from Bangkok or Surat Thani covers the whole country.
Is there a Full Moon Party on Koh Tao?
No — the Full Moon Party is on Koh Phangan, about 90 minutes by speedboat or 2 hours by ferry from Koh Tao. It draws 10,000 to 30,000 people every month and runs on the beach at Hat Rin. Many visitors base on Koh Tao and take a night trip across; others time their stay to overlap with Koh Phangan. Koh Tao has its own much smaller monthly full moon beach parties but nothing on the same scale.
Can you see whale sharks at Koh Tao?
Yes, though sightings are never guaranteed. The best chances are at Chumphon Pinnacle and Sail Rock, with peak seasons around March to April and September to October. Whale sharks are filter feeders and completely harmless — most sightings are 10 to 20 metres below the surface on dives. Even experienced dive leaders are excited when one shows up. If seeing a whale shark is a priority, book early-morning dives during peak season at those two sites.
Koh Tao vs Koh Samui vs Koh Phangan — which island should I choose?
Koh Tao: small, laid-back, diving-focused. Best if you want to dive, escape the resort crowd, or slow down. Koh Samui: the largest, most developed, international airport, luxury resorts and shopping. Best for comfort, convenience and families who want facilities. Koh Phangan: famous for the Full Moon Party but also has quieter beaches. Best for nightlife or a longer stay split between party scene and yoga retreats. All three are connected by ferry — many visitors spend 3 to 4 days on each.
What currency is used on Koh Tao?
Thai Baht (THB). Cash is king on the island — many local restaurants, markets and longtail boats are cash only. ATMs are in Mae Haad, Sairee and Chalok Baan Kao (฿200 to ฿220 withdrawal fee per transaction, regardless of bank). Exchange rates are better at money changers in Mae Haad pier than at airport or hotel rates. Most resorts and dive shops accept card payments; a 2% to 3% fee is common.
Is Koh Tao good for families with children?
Yes, for families with older children who can swim and snorkel. The calm bays like Chalok Baan Kao, Tanote Bay and Shark Bay work well for kids. Bear in mind there are no hospitals on the island — a clinic in Mae Haad handles minor injuries, serious cases go to Koh Samui or mainland. The main road is a single-lane mountain road best not driven at night. Snorkelling, glass-bottom boat tours and Koh Nang Yuan day trips are all family-friendly.
How much does Koh Tao cost per day?
Budget: ฿800 to ฿1,500 per person per day — hostel dorm, street food, cheap Chang beers, no diving. Mid-range: ฿2,500 to ฿5,000 — bungalow or guesthouse with AC, sit-down meals, one fun dive per day. Comfortable: ฿6,000 to ฿12,000 — private villa or resort, good restaurants, daily diving. A PADI Open Water course typically runs ฿9,000 to ฿13,000 all-in. Koh Tao is generally cheaper than Koh Samui but more expensive than Koh Phangan for accommodation.
