Seeing a Doctor on Koh Tao: Walk-Ins, Hours and What to Bring

Do you need an appointment to see a doctor on Koh Tao ?

No. There is no booking system and no referral requirement. Walk in during opening hours, give your details at reception, and wait to be seen. That applies whether you are a two-week visitor, a dive student halfway through an Open Water course, a seasonal worker or a long-term resident. Nobody is triaged out for being a tourist, and nobody needs to be registered with the clinic in advance.

The practical consequence is that the decision to be seen costs you nothing but the time. You do not need to weigh up whether a problem is "worth" the administrative effort of arranging an appointment, which is the calculation that leads people to leave an infected wound another two days.

Opening hours

Our Koh Tao clinic is open daily from 09:00 to 24:00, including weekends and public holidays. The late closing is a deliberate response to how the island actually works. Scooter accidents, bar injuries, marine stings and the point at which a stomach upset becomes genuinely alarming all cluster in the evening, and the realistic alternative to being seen at eleven at night is being seen twelve hours later in a worse state.

Where is the clinic on Koh Tao ?

The Koh Tao clinic is at 1/53 Moo 2, opposite Krungsri Bank. If you are directing a taxi or a friend, the bank is the more reliable landmark — every driver on the island knows it, and addresses here are used far less than landmarks in practice.

From Mae Haad pier the clinic is about 350 metres — a five-minute walk, so it is entirely realistic to be seen between stepping off a ferry and checking in to your accommodation. From the southern end of Sairee Beach it is around ten to twelve minutes on foot, and the route is mostly flat.

If you are too unwell to travel to the clinic, a doctor or nurse can come to your accommodation instead. This is a real option rather than a courtesy: for severe vomiting, high fever, or an injury that makes moving painful, it is often the sensible choice rather than the indulgent one.

What should you bring to the appointment ?

Four things, and only the first is strictly required. Assembling them takes two minutes and removes almost every source of delay at reception.

1. Your passport. Needed for registration. A photograph on your phone is usually workable if the original is in a hotel safe, but bring the document itself where you can.
2. Your insurance policy. The policy number and the insurer's emergency contact line. Photograph both and store the images offline, because signal on the island is not guaranteed at the moment you need them.
3. Any medication you are currently taking. Bring the actual boxes rather than a written list. Brand names vary between countries, and the packaging shows the active ingredient and the dose even when the name is unfamiliar.
4. Any previous medical certificate or notes. Particularly relevant if you are already partway through treatment elsewhere, or if you have been seen at another clinic for the same problem.

What does a doctor visit on Koh Tao cost ?

The doctor's consultation fee starts from 1,000 THB. That covers being seen and examined. Late at night an additional doctor's fee applies — reception will tell you the amount before you are seen. Everything beyond the consultation is charged separately, and the doctor will tell you what something costs before doing it rather than presenting it afterwards.

You can pay by cash, credit card or Thai QR payment, and insurance billing is supported where your policy allows it.

If you intend to claim on travel insurance, say so at reception when you arrive rather than when you pay. Some insurers can be billed directly and others require you to pay and reclaim, and establishing which applies at the start of the visit is considerably easier than untangling it at the end. Our guide to costs and insurance in detail covers the paperwork you should leave with.

When should you come in rather than wait it out ?

Come in the same day for anything that is deteriorating rather than settling. Travellers consistently underestimate two things on this island: how fast a small wound becomes infected in warm, humid, salty conditions, and how ordinary the early symptoms of something serious can look. Both errors are made in good faith, and both are avoidable.

Same-day, without debating it

• any wound that is deep, dirty, will not stop bleeding, or came from an animal bite
• any wound becoming more painful, more red or more swollen rather than less
• fever alongside a wound, or red streaks spreading from it
• ear pain that started during or after a dive
• any neurological symptom after diving — tingling, weakness, dizziness, unusual fatigue
• vomiting or diarrhoea that has stopped you keeping fluids down
• a rash spreading quickly, or any swelling of the face, lips or throat

The general rule

If it is stopping you doing what you came here to do, it is worth being seen. Islands make people stoical in a way that does not serve them: the ferry schedule and the dive course create a strong incentive to wait, and waiting is precisely what converts a consultation and a dressing into a course of antibiotics and four return visits.

What happens during the visit ?

The consultation follows a predictable sequence, which is worth knowing if you are anxious about it. Reception registers you and takes your details. A doctor sees you, takes a history, and examines you. If tests are needed, they are explained and run — laboratory work is available on the island, so results generally come back without you having to leave and return days later. The doctor then explains the diagnosis, the treatment and what to watch for, and you settle the bill on the way out.

Ask for a written summary before you go, particularly if you are travelling onward. Our clinics on Koh Phangan and in Lamai can continue treatment you start here, and written notes travel more reliably than your memory of a conversation held while you felt unwell. If you want to read up on any diagnosis afterwards, stick to established sources such as the NHS health A to Z or the CDC Travelers' Health page for Thailand, rather than travel forums, where island medical advice is frequently confident and wrong.
