The journey to residential treatment is, for most clients, the longest trip they have taken in years that is not a holiday. The logistics of it — passports, flights, prescription medications, what to bring and what to leave — sit on top of an already taxed nervous system, and the small frictions of travel can feel disproportionate when the larger weight of admission is also present. This piece exists to take as much of that friction off the table as possible.
What follows is the practical guide we wish every client received before booking. It is written for adults arriving from the UK, US, Australia, and the EU, which between them account for the large majority of Holina’s international admissions.
Visa: What You Actually Need
Thailand has become one of the most established destinations for international addiction treatment. Tourism Authority of Thailand data places medical and wellness tourism among the country’s fastest-growing service exports, with hundreds of thousands of patients arriving annually for specialised treatment.
Most travellers to Thailand do not require a pre-arranged visa for stays of up to 60 days under the current visa exemption scheme. Citizens of the UK, US, Australia, most EU countries, and dozens of others receive the exemption on arrival. The stamp can be extended once at a Thai immigration office for an additional 30 days, bringing the total to 90 days without leaving the country.
For admissions of 60 days or less, no additional paperwork is required beyond a passport with at least six months’ validity remaining and proof of onward travel. We recommend a return or onward ticket dated within the admission window, even if you intend to extend later. Immigration officers occasionally ask for it. They rarely insist when satisfied with the context, but having it makes the arrival cleaner.
For admissions longer than 60 days, two paths exist. The simpler is to enter on the standard exemption, complete the in-country extension at the 50-day mark, and leave at or before day 90. The slightly more involved is to apply for a 60-day single-entry tourist visa at the Thai consulate in your home country before departure, which can also be extended once on arrival. For admissions approaching or exceeding 90 days, our admissions team will guide the specifics — there is no scenario where length of stay is the reason an admission cannot proceed.
A medical visa is technically available for treatment in Thailand but is rarely the most efficient path for residential addiction admissions. The tourist exemption is sufficient for the vast majority of cases.
Medication: What to Bring, What to Declare, What to Leave Behind
Thailand has stricter rules on controlled medication than most travellers realise. Bringing the wrong medication, or the right medication in the wrong way, can create real problems at customs.
The working principles are these. Bring a 30-day supply of any prescription medication you take regularly, in its original pharmacy packaging, accompanied by a copy of the prescription from your home-country doctor. Bring a written letter from your prescribing physician confirming the diagnosis and the medication, which is the document Thai customs will ask for if anything is queried. For benzodiazepines, opioids, ADHD stimulants, and any controlled medication, the letter is mandatory rather than recommended.
Medications that are routine in many home countries — codeine, tramadol, certain benzodiazepines, stimulants such as Adderall or Vyvanse — require additional documentation in Thailand. Some require advance permission from the Thai FDA, which we can help arrange when your admission medication list is shared with us before travel. Do not bring medications without disclosing them. Travellers who pack quietly and hope for the best, occasionally, encounter difficulties that the documentation would have made trivial.
For clients arriving in withdrawal or with active dependence, the medication question is handled differently. Our admitting clinicians will speak with your home-country prescriber before travel where possible, and we will resume or adjust medication in our clinical setting on arrival. You do not need to bring an extended supply if your dependence is what you are arriving to treat — bring enough for the journey itself, declare it appropriately, and we will handle continuity from there.
What to Pack
The luxury of residential treatment in Thailand is that you need very little. The climate is warm year-round, the dress code throughout the program is informal, and laundry is handled on-site at no additional cost.
A workable list looks like this. Lightweight, breathable clothing — five to seven days’ worth, since you will not need more than that between laundry cycles. Activewear for somatic and movement sessions; comfortable walking shoes for the campus and surrounding paths; sandals for the pool and beach. Modest swimwear, because the campus pool and ocean access are central to the program. A light cardigan or long-sleeved layer for air-conditioned rooms and the small number of cooler evenings. A wide-brimmed hat and reef-safe sunscreen, both genuinely useful on Koh Phangan.
A small number of personal items make the early days easier. A book or two — fiction is more useful than self-help in the first week. A journal, which becomes a meaningful tool as the somatic work progresses. A favourite pillow if you sleep better with a familiar one. Photographs that anchor you to the people you are doing this for, but kept private in your room rather than displayed publicly.
What to leave behind matters as much as what to bring. Laptops are permitted but discouraged for the first two weeks. Smartphones are limited to defined hours, primarily for family contact. Work materials, professional correspondence, and any device or document that pulls you back into the life you are arriving to step away from should remain at home. The campus is intentionally a different rhythm from the one you have been living. Bringing too much of the old rhythm with you makes the transition harder.
The Flight and the Arrival
For UK, US, and Australian clients, the flight is the longest single segment of the journey. Most flights route through Bangkok Suvarnabhumi airport, with a connecting domestic flight to Koh Samui, followed by a 45-minute ferry to Koh Phangan. The total transit is typically 22 to 30 hours door-to-door from the UK and US, somewhat less from Australia and the EU.
We arrange ground transport for every client. A driver meets you at the Koh Samui airport with a Holina sign, takes you to the ferry terminal, and accompanies you on the crossing. A second driver collects you at the Koh Phangan pier and brings you directly to the campus. The handover is seamless, and you do not need to navigate any of the local logistics on arrival. For clients arriving in withdrawal or with significant anxiety about travel, we can arrange a clinical escort for the journey itself, including from the home-country airport in serious cases.
Most clients arrive late afternoon or early evening local time, are settled in their accommodation, fed a quiet meal, and given the first night to sleep. The admissions process formally begins the morning after arrival. There is no expectation of engagement on the day you land.
What Family Members Should Know About the First 48 Hours
Communication is intentionally limited in the first two days. This is not punitive. It is clinical. The transition from active use, travel, and the emotional weight of leaving home is significant, and the first 48 hours are reserved for stabilisation, rest, and the early relational work with the admitting clinician. Families will receive a confirmation of safe arrival from our team, but extended calls or messages typically resume from day three onward, on a schedule that is shared with the family in advance.
This window is one of the most common sources of anxiety for families during admission. Knowing it is coming, and that it is a designed feature rather than a sign of distance, makes the experience meaningfully easier.
A Closing Note on the Journey Itself
The trip to Thailand is, for many clients, the first thing they have done in a long time that is unambiguously for themselves. Even before the clinical work begins, the act of travelling — of passing through airports, of crossing the water, of arriving at a place that has been described to you but you have not seen — has its own quiet effect. The distance is part of the medicine.
If you are reading this in advance of booking, the logistics of the trip are not a barrier we have not seen. Our admissions team handles them daily, in every visa category and from every major origin city. The journey is real work, but it is not work you do alone. The first phone call is the one piece of it you have to start by yourself.
