Koh Tao has no airport: the last stage of your journey is always by boat. The main routes connect with Koh Samui, Koh Phangan, Chumphon and Surat Thani. From Bangkok you can combine a flight, bus or train with the onward ferry.
If you are already on Koh Samui, compare the boat type and departure pier before buying. A direct ferry, a speedboat and a stopover on Koh Phangan are different travel plans, even when they all finish at Koh Tao.
The main gateways to Koh Tao
The island is in the Gulf of Thailand. The transport guides use distances of roughly 70 km from Samui, 55 km from Phangan and 85 km from the Chumphon mainland area as geographical references; ferry routes and their stops determine the actual journey.
Samui (USM), Chumphon (CJM) and Surat Thani (URT) are the airport options described. None is on Koh Tao. Every flight option needs a transfer to a pier, and the ferry must be checked against the flight arrival.
From Bangkok or Chiang Mai
Flying from Bangkok to Samui takes around an hour, followed by the transfer and boat. Chumphon and Surat Thani are mainland alternatives: compare the complete airport-to-island connection, not just the airfare.
Combined bus-and-ferry tickets are another option from Bangkok, with an overland journey to the coast and an onward boat. Confirm the meeting point, transfer arrangements and what happens if a connection is delayed.
A night train to Chumphon lets you do the longer land journey overnight. Check the departure station printed on your current ticket and leave time between the train and the ferry; do not rely on an old station name or an assumed early boat.
From Chiang Mai, you can organise the trip through Bangkok by air or train and then follow one of these connections. Check the actual flight routes available for your dates before choosing an airport.
Koh Samui to Koh Tao: ferry, speedboat or stopover
The direct ferry is described as around 1.5–2 hours, although some itineraries take longer according to their stops and conditions. Morning and afternoon services appear in the route guides; check the dated timetable with the operator.
A speedboat is described as around an hour for the crossing, with less time at sea but a potentially bumpier ride in rough conditions. Compare the boat and the operator’s conditions, especially if you are travelling with children or have concerns about the journey.
You can also break the route with a stay on Koh Phangan: Samui → Phangan → Tao. This is a separate visit, not merely a faster connection. Reserve the two legs and accommodation if you want to spend a night there.
Which pier on Koh Samui?
Maenam is on the northern side of Samui and is associated with Lomprayah in the route guides. Nathon is on the west coast and is another port to check when comparing services. Bangrak, also called Big Buddha Pier, is near the Big Buddha area and appears in routes using speedboats and private boats.
Your ticket must specify the actual pier. Do not choose a taxi destination from the company name alone, since service arrangements can change. Ask whether hotel pickup is included and confirm its meeting time separately from the boat departure.
From Koh Phangan, Chumphon or Surat Thani
From Koh Phangan, the main departure named is Thong Sala, with a crossing of around an hour. Boats can be busy around Full Moon Party dates, so reserve ahead if you have a fixed connection.
From Chumphon, compare departures from Thung Makham Noi or the Chumphon port area, with around 1.5–2 hours by catamaran and longer services depending on the boat. The night-boat option is described as around six hours, with sleeping berths.
From Surat Thani, the routes include transfers towards Tapee or Donsak and onward boats, sometimes via Samui. The quoted route references are around 3–4 hours once underway, excluding waits, with slower night services of around 8–9 hours. Confirm exactly which legs your ticket covers.
From Phuket, Krabi or Phi Phi
Travelling from the Andaman coast to the Gulf involves an overland connection. From Phuket or Krabi, compare bus or minivan transfers towards Surat Thani and then the boat to Koh Tao. From Phi Phi, first take a boat to Krabi or Phuket and continue overland.
Some operators bundle pickups and onward transport into a combined ticket. Treat the route as a full travel day and check every connection. If you are visiting both coasts, compare the destinations in the Thailand diving hub and our Koh Phi Phi school.
Booking, luggage and sea conditions
Lomprayah, Seatran Discovery, Songserm and Boonsiri are operators to compare. Check their actual routes, fares, luggage allowance and pickup terms; do not assume tickets from different companies are interchangeable.
Arrive at least 30 minutes before departure, or as instructed by the operator. Keep valuables with you, travel with luggage you can carry over ramps or steps, and bring water, sun protection and some baht. Ask a health professional about seasickness options if needed, especially before combining medication and diving.
The Gulf’s wetter, rougher period is described as late October–December. Crossings can change or be cancelled, and popular services fill around holidays and events. Leave a buffer before an international flight; the itinerary recommends a spare day between the last boat and that departure.
Arriving at Mae Haad and getting around
The usual arrival is Mae Haad pier. Confirm any pickup with your accommodation or school in advance rather than assuming it is included. Songthaew pickups and other local transfers connect with areas such as Sairee and Chalok Baan Kao.
Walking works well around Sairee Beach. To explore Mango Bay to the north, Tanote Bay to the east or Shark Bay to the south, compare a local taxi, a bicycle for suitable short routes or a longtail water taxi. Scooter hire is another option for experienced riders: the roads can be steep and uneven, so inspect the vehicle and read the contract.
Keep your travel documents secure, bring light clothing and insect repellent, check that your travel insurance covers your activities and respect local customs. Take rubbish away from beaches and follow the guidance for each water activity.
Fit the journey around your diving
Our SSI school in Koh Tao has been teaching on the island since 2014. Share your arrival time when asking about a Try Scuba or Open Water course, and confirm the programme before booking tight connections.
Travel conditions and dive conditions are related but not identical. Read about the best time to dive in Koh Tao and the dive sites around the island before choosing your plans.
Frequently asked questions
Can you fly directly to Koh Tao?
No. Fly to a connecting airport such as Samui, Chumphon or Surat Thani, transfer to the pier and continue by boat.
How long is the ferry from Koh Samui?
The direct-route reference is around 1.5–2 hours, with variation by service, stops and sea conditions. Confirm the departure pier and the time on your ticket.
Can you stop on Koh Phangan?
Yes. You can book Samui to Phangan and a later Phangan to Tao trip, allowing time to stay on the island rather than making an immediate connection.
Should you book a boat straight after a flight?
Allow for baggage, the transfer and check-in, and check the last sailing. A tight connection has little room for delays.
