Koh Tao, a popular small island in the Gulf of Thailand, is best known for its diving and clear tropical waters. It is considerably smaller and more relaxed than nearby Koh Samui, but there is still plenty to do beyond diving, with beaches, viewpoints, snorkelling, restaurants, bars and a surprisingly active nightlife scene.
The island attracts a mixture of visitors, from people coming specifically to learn to dive to travellers looking for a few quieter days away from the larger tourist centres of Thailand. It is also a popular stop on island-hopping trips that include Koh Samui and Koh Phangan.
This guide will cover the practical side of visiting Koh Tao, including where to stay, the best beaches and areas, diving and snorkelling, getting around, when to visit and the things worth knowing before you arrive.
Where is Koh Tao?
Koh Tao is located in the Gulf of Thailand, north of Koh Phangan and Koh Samui. It is part of Surat Thani Province and is one of the smaller inhabited islands in the area.
Despite its relatively small size, the island has several distinct areas. Most visitors spend their time around Mae Haad and Sairee Beach, while other parts of the island are quieter and more focused on beaches, resorts and diving.
There are no major cities or large shopping centres on Koh Tao. The island is much more compact and has a distinctly island-oriented feel.
What is Koh Tao known for?
Koh Tao is particularly famous for scuba diving. The island has a large number of dive schools and is one of the most popular places in Thailand for people learning to dive.
You don’t necessarily need to be an experienced diver to enjoy the island. Beginners can take an introductory course or complete an Open Water certification, while qualified divers have numerous dive sites and operators to choose from.
Snorkelling is another major attraction, with several beaches and nearby areas offering opportunities to see tropical fish and marine life without scuba equipment.
Away from the water, Koh Tao is known for its beaches, viewpoints, relaxed restaurants and bars. Sairee is the main centre for much of the island’s tourist activity and has the largest concentration of accommodation, restaurants and nightlife.
Scuba diving in Koh Tao
For many visitors, diving is the main reason to come to Koh Tao.
There are dive schools throughout the island offering everything from introductory dives to internationally recognised certification courses. The island’s relatively low-cost diving industry has made it particularly popular with backpackers and first-time divers.
Popular dive sites around Koh Tao include Chumphon Pinnacle, Southwest Pinnacle, Shark Island and Japanese Gardens, although the sites visited can vary depending on weather, conditions and the diver’s experience.
Koh Tao is also a popular place to learn to dive. Courses normally take several days and combine classroom or theory work with practical training and dives.
You don’t have to dive, however. Snorkelling trips and boat trips are widely available, and several beaches provide easy access to the water.
Where to stay in Koh Tao
Sairee Beach is generally the obvious choice for visitors who want to be close to restaurants, bars, shops and nightlife. It is also convenient for travellers who want plenty of accommodation choices within walking distance.
Mae Haad is another practical option. This is where the main ferry pier is located, making it convenient if you are arriving with luggage or only staying for a short time.
Other parts of the island are better suited to visitors looking for a quieter stay. There are resorts and smaller accommodation options around beaches and bays away from the main tourist centre.
The best area to stay depends largely on what you want from the trip. Someone visiting primarily to dive may have different priorities from someone looking for nightlife or a quiet beach holiday.
The beaches of Koh Tao
Koh Tao has a number of beaches and smaller bays, ranging from busy and developed areas to relatively secluded spots.
Sairee Beach is the longest and busiest beach on the island and is closely associated with the main tourist area. It is lined with accommodation, restaurants and bars and is a popular place to watch the sunset.
Mae Haad is more of a working and transport area, although it also has a beach and is convenient for visitors staying near the pier.
Other beaches and bays around the island include Chalok Baan Kao, Shark Bay, Tanote Bay and Sai Daeng. Some are easier to reach than others, and road conditions and access can vary.
Koh Tao’s smaller beaches are one of the reasons it is worth exploring beyond the main Sairee and Mae Haad areas.
Things to do in Koh Tao
Diving and snorkelling are the obvious activities, but they are not the only things to do on the island.
Popular activities include:
- Visiting different beaches and bays
- Taking a snorkelling or boat trip
- Hiking to one of the island’s viewpoints
- Watching the sunset around Sairee Beach
- Exploring the island by scooter
- Taking a day trip to nearby Koh Nang Yuan
- Trying Thai and international food
- Enjoying the bars and nightlife around Sairee
Koh Nang Yuan, a small group of islands just off Koh Tao, is particularly popular for day trips. It is known for its beaches, snorkelling and distinctive viewpoint.
Getting around Koh Tao
Koh Tao is small enough that most of the main tourist areas are relatively easy to reach, but the island is hilly and some roads can be steep.
Motorbikes are a common way for visitors to get around, although anyone hiring one should be comfortable riding before doing so. Road conditions can vary, particularly away from the main areas.
Taxis and other local transport are also available, although prices can be less predictable than visitors might expect on a larger Thai island.
Walking is practical in some areas, particularly around Sairee and Mae Haad, but less so if you want to explore different parts of the island.
How do you get to Koh Tao?
Koh Tao does not have its own airport, so most visitors arrive by ferry.
The usual routes involve travelling through Koh Samui, Koh Phangan or the mainland and then taking a ferry to Koh Tao. Ferry services connect the island with other destinations in the Gulf of Thailand, although schedules vary depending on the season and weather.
Flying to Koh Samui followed by a ferry is one option for travellers coming from Bangkok or elsewhere in Thailand. Another common route is to travel overland to Surat Thani or Chumphon and continue by ferry.
The journey is part of the planning involved with visiting Koh Tao, particularly if you are travelling with luggage or connecting between islands.
When is the best time to visit Koh Tao?
Koh Tao can be visited throughout much of the year, but weather conditions vary between seasons.
The main tourist season generally brings more reliable weather and is also a popular period for diving and island travel. The island can become noticeably busier during holidays and peak travel periods.
The Gulf of Thailand has a somewhat different weather pattern from Thailand’s Andaman Coast, so it is worth checking conditions specifically for Koh Tao rather than assuming the weather will be the same as Phuket or Krabi.
Rain and rough seas can affect ferry services as well as outdoor activities, so weather is particularly relevant when planning a short visit.
Is Koh Tao expensive?
Koh Tao offers a wide range of accommodation, food and activities, so the cost of a visit can vary considerably.
Budget accommodation and inexpensive Thai food are available, while there are also more expensive resorts, restaurants and diving options.
Diving will naturally add to the cost of a trip, particularly if you are completing a certification course rather than simply taking a fun dive or snorkelling trip.
Compared with larger Thai destinations, some island-related costs can also be higher because supplies and visitors have to be transported to the island.
Is Koh Tao good for first-time visitors?
Koh Tao can work well for a first visit to Thailand, particularly for travellers who are interested in beaches, diving and a relatively compact island environment.
It is less urban and considerably smaller than Koh Samui, so visitors looking for extensive shopping, large resorts or a wide range of attractions may prefer a larger destination.
For someone who wants to spend a few days swimming, snorkelling, diving, eating, relaxing and exploring an island, however, Koh Tao offers plenty to do without requiring a complicated itinerary.
Is Koh Tao good for families?
Koh Tao is visited by families as well as couples, solo travellers and groups of friends.
The island has beaches, snorkelling and other activities that can appeal to families, although the suitability of particular areas depends on the age of the children and what sort of holiday you want.
Sairee has the greatest concentration of restaurants and activity, while quieter parts of the island may be preferable for families looking for a more relaxed environment.
Parents should also take into account the island’s hills, roads and boat transfers when choosing accommodation.
Is Koh Tao good for nightlife?
Koh Tao has a lively nightlife scene, particularly around Sairee Beach.
The atmosphere is generally more casual and backpacker-oriented than the nightlife found on larger Thai islands. Bars, beach venues and smaller parties are common, with activity increasing during busy periods.
Visitors looking for nightlife will generally find Sairee the most convenient area to stay, while other parts of the island can be considerably quieter at night.
How long should you stay in Koh Tao?
A few days is enough to see some of the main beaches and experience the island, but a longer stay makes more sense if diving is one of the main reasons for your visit.
Someone completing a diving course may spend several days on the island without much spare time for sightseeing. Visitors simply looking to relax can also easily spend a week or more exploring different beaches and bays.
Koh Tao is commonly combined with Koh Phangan and Koh Samui, making it possible to include the island as part of a wider Gulf of Thailand itinerary.
Koh Tao travel information
Koh Tao is small, but choosing the right area and understanding the transport connections can make a significant difference to a visit.
Whether you are coming specifically to dive, looking for a beach holiday, travelling around the Gulf islands or simply want to spend a few days somewhere different, it is worth looking beyond the main tourist strip before deciding where to stay.
More detailed guides to Koh Tao’s beaches, areas, accommodation, diving, transport, things to do and practical travel information will be added as the site develops.
