Rehab on Koh Phangan

The short answer

We found one English-speaking residential rehab on Koh Phangan, an island in the Gulf of Thailand best known for its monthly Full Moon Party. The island has a small public community hospital, and serious emergencies may need a boat transfer to Koh Samui or the mainland.

There is no airport on the island, so most people fly to Koh Samui and cross by boat.

• About 1 English-speaking center
• US$9,700–17,700 per 28 days (directory)
• Fly to Koh Samui (USM), then boat

How many rehabs are there on Koh Phangan?

We found one English-speaking residential center on Koh Phangan, out of an estimated 25–30 in Thailand.^[1]

With one center, there is nothing to compare locally. Check it against the same standards you would use anywhere, and think honestly about whether an island suits your situation, both medically and personally.

We don't name or rank private centers yet, and we accept no payments, referral fees or commissions from them. For more choice, see our Chiang Mai guide or the overview in Rehab in Thailand.

Is a party island a good place to recover?

Koh Phangan's Full Moon Party is held every month and draws Thai and foreign revellers.^[2] In 2018 the Bangkok Post reported that drug use had been reported on the island for many years, and that the Office of the Narcotics Control Board sent hundreds of officers there, with searches and urine tests for some travellers at piers.^[2]

The UK government says attacks in Thailand are most common during full moon parties or similar events and near bars late at night. It also warns that drink spiking happens in tourist areas, and that possessing Class A drugs can lead to the death penalty.^[3]

The party also matters for a quieter reason. The US National Institute on Drug Abuse explains that cues in a person's environment that have become linked with drug use can trigger cravings, even years later.^[4] For someone whose drinking or drug use was tied to parties, an island where parties are part of the local economy can be a hard place to be once treatment ends.

That doesn't rule the island out. Ask how far the center is from the party areas, what happens during party weeks, whether outings are supervised, and what the plan is if you want to stay on the island after treatment.

How much does rehab on Koh Phangan cost?

A directory lists the island's center at US$9,700 to US$17,700 for 28 days.^[1]

The center itself quotes on request, so ask for a written price for your exact stay. That range spans the middle and upper part of what English-speaking centers across Thailand publish: about US$4,300 to US$25,700 for 28–30 days, with an average of about US$12,000.^[1]

On an island, also ask about costs that are easy to miss: boat and airport transfers, hospital care, and medical transfer to Koh Samui or the mainland if you need it. Our cost guide explains price tiers, extras and insurance.

What medical care is there on Koh Phangan?

Koh Phangan Hospital is the island's public hospital. Thailand's hospital accreditation body lists it as a community hospital, with its current HA certificate running to June 2029.^[7]

The larger public hospitals in Surat Thani province are Koh Samui Hospital, a general hospital on the neighbouring island,^[8] and Surat Thani Hospital on the mainland, listed as a center hospital.^[9]

We could not find an official statement of which cases Koh Phangan Hospital sends on, or where to, so we can't tell you exactly what it can and can't handle. What we could confirm is that even Koh Samui sends emergency patients to the mainland: in 2019 the director of Samui Hospital said island hospitals use speedboats for these transfers, and that at night or in rough seas a transfer can take up to six hours.^[10]

The UK government warns that boats in Thailand can sink or collide, with overloading, poor maintenance and rough seas, especially in the monsoon season, among the causes.^[3] It also says all hospitals require a guarantee of payment before treating patients, and that public hospitals do not always meet UK standards outside Bangkok.^[11]

In practice, ask the center for a written emergency plan: which hospital it uses for what, how a patient gets to Koh Samui or the mainland at night or in bad weather, and who pays. Check that your travel insurance covers emergency medical transfer.

Is there government drug treatment near Koh Phangan?

Thailand's public drug-treatment system is led by the Princess Mother National Institute on Drug Abuse Treatment, often called the Thanyarak Institute, in Pathum Thani province north of Bangkok. It works with six regional Thanyarak hospitals run by the Department of Medical Services.^[12][13]

None is in Surat Thani province. The regional hospitals are in Chiang Mai, Mae Hong Son, Udon Thani, Khon Kaen, Songkhla and Pattani,^[14] so the nearest to Koh Phangan is Thanyarak Songkhla Hospital in the far south.^[15] In 2023 the Ministry of Public Health also set out to open a smaller inpatient unit, called a Mini-Thanyarak, in a community hospital in every province; we could not confirm which hospital provides one in Surat Thani.^[13]

These services are funded through government budgets and Thailand's Universal Coverage scheme, and they work in Thai.^[13] We found no information in English for foreign patients. If you live in Thailand and want to use them, ask Koh Phangan Hospital or the Surat Thani Provincial Public Health Office.

How do you get to Koh Phangan?

• No airport on the island. An airport project on Koh Phangan was halted in 2015 and, as of 2024, had not been revived.^[16] Most international travellers connect through Bangkok.
• Via Koh Samui or Surat Thani. You can fly to Koh Samui (USM) and take a boat to Koh Phangan, or fly to Surat Thani on the mainland and travel on to the ferry piers at Don Sak, where boats run to Koh Samui and on to Koh Phangan.^[2] Ask whether the center arranges the transfer and meets you, especially if you are unwell.
• Weather and flooding. Boat crossings depend on the sea, so leave spare time between flights and ferries. When we checked on 11 October 2026, the UK government's travel advice also carried a 28 September update on severe flooding in Bangkok and nearby provinces.^[17]
• Visas and medication. Rules depend on your nationality and change over time. Read our visa guide and medication guide, and talk to your doctor before you travel.

Eight questions to ask a center on Koh Phangan

Ask for written answers to these questions before you pay a deposit or book flights. On an island, the emergency plan deserves as much attention as the therapy.

1. Is it licensed, and operating at this address? Ask for a copy of its facility licence and check the name and address on the Ministry of Public Health's online register. Our safety guide shows how.
2. Can it legally treat drug addiction? If drugs are involved, ask for written proof that it is recognised to provide drug treatment, not only a facility licence.
3. Who manages withdrawal, and where? On site or in a hospital, who supervises it overnight, and which doctor is responsible for your care.
4. What is the emergency plan? Which hospital it uses on the island and beyond, how a patient reaches Koh Samui or the mainland at night or in rough seas, and who pays.
5. Who provides therapy, and how much? Therapists' qualifications, one-to-one sessions each week, group sizes, and whether a psychiatrist can assess you.
6. What is the full price, in writing? What is included and extra, including boat and airport transfers, the deposit and the refund policy if you leave early.
7. How close is it to the party areas? What happens during Full Moon Party weeks, and how outings and free time are supervised.
8. What happens after you leave? Online sessions, referrals to services in your own country, and a plan for where you will stay if you are not flying straight home.
